THE OLDEST CONTINENTAL ROCKS ARE 4 BILLION YEARS OLD, WHEREAS THE OLDEST SEAFLOOR ROCKS ARE 200 MILLION YEARS OLD. EXPLAIN WHY THESE AGES DIFFER.
The difference why the ages of the rocks is different is because before it becomes too old, the oceanic crust is recycled at subduction zones.
What is continental crust?The continental crust is a layer of granitic, sedimentary, and metamorphic rocks that forms continents and areas of shallow seabed near their shores (continental shelves). Crust of the continent The continental crust is mostly made up of various types of granites. The rocks of the continental crust are frequently referred to as "sial" by geologists.
Continents are preserved preferentially in this way compared to oceanic crust, which is continuously recycled into the mantle. This explains why most ocean floor rocks are less than 200 million years old, whereas the oldest continental rocks are over 4 billion years old.

What is the populationd density, and is it sparse, moderate or dense?
Country: Poland, Population: 38 530 000, Area KM2 = 312.679
Based on the available I formation, the Population density of Poland is considered to be Dense Population because it is more than 100 per square kilometer.
What is Population DensityPopulation Density is a term that is used to describe the total number of people living in an area per unit of measurement.
There are various types of Population density which include the following;Dense Population: this is a population density that means the number of people living in an area is more.Moderate Population: this is a population density that inferred that the number of people living in an area is average or optimum, not too high and not too low.Sparse Population: this implies that the population of people living in an area is very low compared to the available space.Therefore, here we have population divided by unit area = 38,530,000 ÷ 312,679 = 123.23.
Hence, in this case, it is concluded that since the population of Poland is beyond 100 per square kilometer, it is considered very high, which means Dense Population density.

The coordinate of point T are (0,2). The midpoint of ST is (4,- 7)int s
The question requires the midpoint formula:
Midpoint = (x1+x2)/2, (y1,y2)/2
What is the Coordinate Point of S ?Given that we know the midpoint, and the coordinates of one point but not the other, we can solve for the coordinates by plugging in what we know
The coordinates of point T are (0,2). The midpoint of ST is (4,−7)
Midpoint [xm,ym] = [(x1+x2)/2, (y1+y2)/2]
We can break up the midpoint formula to solve for our missing x and y
xm = (x1+x2)/2,
ym = (y1+y2)/2
Substitute our known values Midpoint (4,-7) and the second point T (0,2) to solve for the first point S
4 = (x1+0)/2
4 = x/2
x = 8
-7= (y1+2)/2
-14 = y + 2
y = -12
Therefore the coordinates of point S are (8,-12)

DESCRIBE HOW THE GAP IS FILLED WHEN TWO TECTONIC PLATES MOVE AWAY FROM EACH OTHER.
Divergent boundaries can also result in the formation of volcanic islands, which happen when plates separate and leave gaps that molten lava rises to fill the gap when two tectonic plates moves away from each other
what are tectonic plates
A tectonic plate, also known as a lithospheric plate, is a substantial slab of solid rock with an uneven shape that is typically made up of both continental and oceanic lithosphere.
Only a portion of the plate boundary is affected by each eruption at any one time, but when it does, it fills up the opening gap as the two opposing plates drift apart.
Asthenosphere hot rock rises, cools, and forms new lithospheric rock. forms new lithospheric rock when it cool

Answer:
When two tectonic plates move away from each other, a gap or rift is formed between them. This process is called a divergent boundary. The gap is then filled by magma that rises from the mantle, which is a layer of hot, molten rock beneath the Earth's crust.
As the magma rises, it cools and solidifies to form new crust. This process is called solidification or crystallization. Over time, the newly formed crust continues to spread and push the two plates further apart.
In some cases, the magma may reach the surface and create volcanic activity. This happens when the magma is less dense than the surrounding rock and rises through a vent or fissure to create a volcano.
The process of two tectonic plates moving away from each other and the resulting formation of new crust is known as seafloor spreading. This occurs most commonly along the mid-ocean ridges, which are long underwater mountain chains that run through the world's oceans.

Assume Earth’s revolution INCREASED and its rotation DECREASED. Which set of data would go with these changes?
Length of year 340 days; length of day 26 hours
Length of year 370 days; length of day 28 hours
Length of year 380 days; length of day 23 hours
length of year 330 days; length of day 20 hours
If the rotation of Earth was to decrease, and the revolution was to increase, the set of data that would go with this change is A. Length of year 340 days; length of day 26 hours
What happens if the Earth's rotation decreases?The rotation of the Earth determines the number of hours in a day we have. This is because the Earth rotates once on its axis in 24 hours. If the rotation was to decrease, then the day would be longer as the rotation would take a longer time. A 26 hour day would be possible.
If the Revolution of Earth increased however, then we would have shorter years because a revolution is the time it takes the Earth to move around the sun. If the Earth moves faster, then there would be fewer days which makes 340 days possible.

MORTON, P. 61. SUMMARIZE THIS PASSAGE:
"[Talking about 'saving the planet'] weakens
the ties between the natural and the human. It
channels concern away from your life or the
lives of others, towards the well-being of an
abstract geophysical entity. ... ¶ Concern for
the planet itself is also... ...misplaced. Unlike
humans and their societies, unlike many of the
landscapes and creatures that people love and
depend upon, the planet is not fragile in any
way." (Morton, p. 61)
The above passage describes our planet Earth, in which the author Morton tries to move our attention to the concern of saving the planet.
What is Earth?
The Earth is the third planet from the Sun and the only known astronomical object to support life. Even though the Solar System is filled with a lot of water, only Earth is home to liquid surface water. The oceans cover around 71% of the Earth's surface, dwarfing its lakes, rivers, and polar ice, while Land, made up of continents and islands, makes up the remaining 29% of the Earth's surface.
With the help of technology, humans have interacted with the surface of the earth and made their homes, and developed socially and culturally. But as the pace of technology has sped up, there are many environmental issues as well that has been arisen. About that only Morton is trying to describe. He says that when it comes to saving the planet, the relationship between humans and nature has become weak, which made us all careless of our own and others' life. Now even humans have stopped thinking about saving the planet earth. Further, he says just like human societies are unbreakable and the way humans have influenced the planet earth culturally, our planet earth is also not fragile in one way or the other.

The type of plate boundary that would be found along the Coastline near the Japan's Volcanic mountain range will be a convergent boundary, which is where the Pacific Plate is moving beneath the adjacent continental plates with a process known as subduction.
What is a convergent boundaries?In geography, a convergent boundary is also known as a destructive boundary, this refers to an area on Earth where two or more lithospheric plates collide. It happens when one plate eventually slides beneath the other, the process is known as subduction.
The subduction zone is mostly defined by a plane where many earthquakes occur also known as called the Wadati–Benioff zone; these collisions happen on scales of tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, deformation etc.
In conclusion, the convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. However, the geologic features that relates to convergent boundaries varies depending on crust types.

PLEASE HELP. How does the doctrine of uniformitarianism help us understand the history of earth
Answer:
uniformitarianism
Explanation:
Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle,[1] is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe.[2][3] It refers to invariance in the metaphysical principles underpinning science, such as the constancy of cause and effect throughout space-time,[4] but has also been used to describe spatiotemporal invariance of physical laws.[5] Though an unprovable postulate that cannot be verified using the scientific method,[6] some consider that uniformitarianism should be a required first principle in scientific research.[7] Other scientists disagree and consider that nature is not absolutely uniform, even though it does exhibit certain regularities.
In geology, uniformitarianism has included the gradualistic concept that "the present is the key to the past" and that geological events occur at the same rate now as they have always done, though many modern geologists no longer hold to a strict gradualism.[9] Coined by William Whewell, it was originally proposed in contrast to catastrophism[10] by British naturalists in the late 18th century, starting with the work of the geologist James Hutton in his many books including Theory of the Earth.[11] Hutton's work was later refined by scientist John Playfair and popularised by geologist Charles Lyell's Principles of Geology in 1830.[12] Today, Earth's history is considered to have been a slow, gradual process, punctuated by occasional natural catastrophic events.
