Almost all rocks are minerals, but different rocks contain different mixtures of minerals. There are three main groups of rocks: sedimentary, igneous and metamorphic rocks.
Members of the plagioclase group are the most common rock-forming minerals. They are important for most of the dominant minerals in the igneous rocks of the earth's crust. They are the main components of many intrusive and extrusive igneous rocks, including granite, diorite, gabbro, rhyolite, andesite, and basalt. Rocks that contain many dark silicate materials and plagioclase in feldspar are basaltic in composition. Basalt rock contains minerals of the pyroxene group, which give the minerals their dark color.
It can be as light as dark green or as dark as black. Plagioclase (feldspar) is widespread and common in many igneous and metamorphic rocks, and to a much lesser extent in some immature sedimentary rocks. In general, the keys to identifying plagioclase are its absence (color), low birefringence, and twinning.

on the western coasts of central and sounth america, would ocean water temperatures be warmer or cooler than normal during an el nino year?
The equator's weakening winds during an El Nao year cause the water's surface to warm, which in turn causes the winds to weaken even more.
Does an El Nio cause a warming or cooling of the western Pacific Ocean?Warm surface water from the western Pacific to the coast of northern South America moves eastward along the Equator as a result of these variations in air pressure and wind speed. The thermocline, the ocean depth separating warm surface water from cooler water below, is further lowered by these warm surface waves.
Why is the water so chilly along South America's west coast?This is because cold, nutrient-rich water can upwell from deeper levels off the northwest coast of South America due to the trade winds moving from east to west around the equator.

cold weather , water that drips from roofs becomes icicles ,therefore what type of phase change is this
Answer:
The formation of icicles from water that drips from roofs in cold weather is an example of the phase change from a liquid to a solid.
Explanation:
The formation of icicles from water that drips from roofs in cold weather is an example of the phase change from a liquid to a solid. Water is a substance that exists in three main states or phases: solid (ice), liquid (water), and gas (water vapor). When water is exposed to cold temperatures, the kinetic energy of its molecules decreases, and the water becomes less able to move freely. As a result, the water molecules begin to slow down and form a more organized, crystalline structure, and the water changes from a liquid to a solid, forming icicles.
The process of water changing from a liquid to a solid is known as freezing, and it is the opposite of the phase change from a solid to a liquid, which is called melting. When water freezes, it releases latent heat, which is the energy that is stored in the water molecules as they change from a liquid to a solid state. This release of latent heat can help to keep the surrounding air warm, and it can prevent the temperature from dropping too low, which can be beneficial for plants and animals in cold climates.
Overall, the formation of icicles from water that drips from roofs in cold weather is an example of the phase change from a liquid to a solid, and it is an important part of the Earth's natural processes and cycles.

Why does mainland europe have a wider variety of plant life than the british isles?.
Mainland Europe has a more diverse climate than the British Isles. This is because Mainland Europe have a wider variety of plant life than the British Isles.
Western Europe is situated at northern scopes, however has a milder environment than different spots at similar scopes. This is on the grounds that the majority of Western Europe lies in the way of the Westerlies. These are solid breezes that movement from west to east. They are warmed by the warm water of the North Atlantic Flow, which starts in the tropical waters of the Caribbean Ocean. This warm, clammy air moves inland on the Westerlies. It carries gentle temperatures and downpour to the vast majority of Western Europe consistently. Summers are cool, and winters are gentle. This environment is known as a marine west coast environment. Since there are no waterfront mountain reaches to stop it, the Westerlies blow across the European landmass.

Explanation:
Choose the claim that is best supported by evidence, explaining why the rock of the rocky mountains and great plains have surprisingly similar mineral compositions.
German researcher Alfred Wegener proposed that the Earth’s continents were floating. He called this Continental Drift Theory. This is the best supported by evidence, explaining why the rock of the rocky mountains and great plains have surprisingly similar mineral compositions.
Wegener thought of this thought since he saw that the shorelines of western Africa and eastern South America seemed to be unique pieces. He contemplated whether they could have once fit together and afterward floated separated. This mainland was subsequently named Pangaea.
One kind of proof that emphatically upheld the Continental Drift Theory is the fossil record. Researchers have tracked down fossils of comparative sorts of plants and creatures in rocks of comparable age. These stones were on the shores of various landmasses. This proposes that the landmasses were once joined.

Determine the acceleration of earth due to its motion around the sun. Assume the earth's orbit to be circular with a radius of.
The acceleration of the earth around the sun is 5.95 103 m/s2, which is the definition of centripetal acceleration.
Definition of Centripetal AccelerationA motion feature that applies to objects moving in a circular motion is called centripetal acceleration. It is referred to as moving with centripetal acceleration when an item moves in a circle including its acceleration vector pointing inside the direction of the circle's center.
The following is the result for the acceleration of the earth around the sun according to the definition of centripetal acceleration:
a = 5.95 10⁻³ m / s²
A body accelerates centripetally when all of its energy is put toward changing the direction of its velocity while maintaining a constant value for its modulus.
a= [tex]\frac{v^{2} }{r}[/tex]
They show that the circular orbit's radius is r = 1.5 10⁸ km = 1.5 10¹¹m.
Since the speed is constant in a circular motion, we may use the uniform motion relation to calculate the speed.
[tex]v = \frac{L}{t}[/tex]
The orbital circle has the following radius:
L = 2π r
The period is the amount of time required for an orbit to complete.
v = 2πr / t
The Earth's orbit has a year-long period.
T = 3.154 10⁷ s
Now let's determine the velocity.
v = 2 pi X 1.5 X [tex]10^{11}[/tex] / 3.154 10⁷
v = 2.988 10⁴ m / s
We can now determine the acceleration.
a= [tex]\frac{(2.988 X 10^{4} )}{1.5 X 10^{11} } ^{2}[/tex]
a = 5.95 10⁻³ m / s²

When two continental plates collide in a convergent boundary, they squeeze together to form what?.
The result is Mountains.
The Himalayan mountains were created during the collision between the Indian subcontinent and the Eurasian continent some 45 million years ago. According to the scientific hypothesis of plate tectonics, the Earth's crust is made up of around nine major plates and numerous smaller ones that are arranged like jigsaw pieces all over the world. The mantle of the Earth, an inner layer made up of rocks that encircles the planet's core, is traversed by these plates.
Most geologists adhere to plate tectonics as a unifying theory in geology since it helps them explain these changes that take place to the Earth's crust. The earth's surface experiences folds and faults as a result of the two plates buckling, which frequently results in the formation of mountain ranges. The biggest mountains on Earth were actually produced by this procedure.

in a forested watershed, if you remove (or log) the trees, what happens to evapotranspiration and to runoff?
If the trees are removed then evaporation drops and stream flow increases. It will impact on the streams in the watershed.
In the forest watershed, trees and forests absorb and use tremendous amounts of water for growth. A single mature oak tree can consume over 40,000 gallons of water in a year. In Pennsylvania forests, an average of 24 inches of the annual 40 inches of rainfall is taken up by trees through evapotranspiration. Evapotranspiration is defined as the movement of water from the ground through the tree and leaves, evaporating back into the environment that also serves to cool and modify surrounding summer temperatures. If the forest is removed or harvested, evaporation drops to 14 inches and stream flow increases to receive 26 inches of the annual 40 inches of precipitation. So, just the removal of forests can have an impact on streams in the watershed.

How do I explain the diffusion of popular culture using the concept of cultural diffusion?
Answer: Look at Explanation.
Explanation: The definition of cultural diffusion (noun) is the geographical and social unfold of the one of a kind elements of 1 extra cultures to one of a kind ethnicities, religions, nationalities, areas, etc. Cultural diffusion is set the spreading of tradition over time. There are many varieties of cultural diffusion, and on this manual we are able to cross over the kinds and offer examples. The following examine publications on this unit collection cross into extra examples of cultural diffusion in precise anciently and contemporary-day contexts. Relocation Diffusion takes place whilst humans flow from their unique area to every other and convey their improvements with them. Immigration from united states to united states, metropolis to metropolis, etc. As they relocate to a brand new area, they create their ideas, cultural culture including meals, track, and extra. As loads of people immigrate to a brand new surroundings, they create alongside their cultural connections, influencing others withinside the new environments. Relocation diffusion also can be compelled as opposed to chosen. Expansion Diffusion is the unfold of an concept thru a populace in which the quantity of these inspired grows constantly larger. There are 3 sub-varieties of Expansion diffusion: Stimulus, Hierarchical, and Contagious. Contagious Diffusion is described as distance-managed spreading of an concept thru a nearby populace with the aid of using touch from character to character. Similarly to a disease, it spreads swiftly from one supply to others from character to character. Another manner to think about it’s far just like the spreading of a wooded area fire. Hierarchical Diffusion is whilst a concept spreads using passing first a few of the maximum related people. Hence, spreading to different people. Think of the chain of command in businesses, and the authorities. There’s truly of a hierarchy in phrases of role of authority. Stimulus Diffusion is whilst an concept diffuses from its cultural fireside outward, however the unique concept is modified with the aid of using the brand new adopters. Almost all cultural diffusions may have a few thing of stimulus diffusion due to the methods tradition adapts to new environmental, social, and political conditions. Maladaptive Diffusion is the adoption of diffusing developments that aren’t sensible or reflective of a region’s surroundings or tradition. The term society would mean the whole gamut of activities, beliefs, way of living, behaviours, rituals, arts, ethics, and behaviour patterns of a culture. Yet despite the vast meaning of society, the aspects of society being as well varied and divergent, it is not easy to supply a partnership between society and psychology. There are two common means by which the association between psychology and culture is examined via intra-cultural psychology or behaviour patterns within a particular society and intercultural psychology or behaviour and mental characteristics between cultures. Intra-cultural psychology looks to comprehend the social basis of habits by studying the peculiarities of a society. Its rules, and norms and demonstrates how traditions shape. Or affect the collective subconscious of individuals within the community. Nevertheless, in psychology, this is thought about as ‘cultural psychology. An uncomplicated term denoting the research study of cultural customs and their impacts on the psychology of people. This type of categorization might be misleading as it often tends to see cultures. As essentially different units and highlights differences instead of similarities. Cross-cultural psychology focuses on finding universal patterns of habits or ideas that prevail among individuals of all cultures. This is what has described below as ‘inter-cultural psychology. The terms ‘intracultural and ‘inter-cultural psychology would undoubtedly be more conducive to discovering psychology that reveals convergent cultural actions amongst individuals across cultures.

By definition, two shapes are congruent if you can map one onto the other using rigid transformations (a sequence of one or more rotations, translations, and reflections). Since any sequence of rigid transformations performed on a triangle result in a congruent triangle, what does that imply about the corresponding side lengths and angle measures for two congruent triangles?
When two triangles' matching sides and angles are of equal length, two triangles are said to be congruent.
If the matching angles and sides of two triangles are congruent, then two triangles were said to have been comparable.
What is congruence?Two figures or objects are said to be congruent in geometry if they are the same size and shape, or if one is the mirror reflection of the other.
Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a mixture of rigid motions like translation, rotation, and reflection.
