Answer 1

Answer:

You havent attached the choices so we cant tell u the answer

Answer 2

Answer:

I do not see the options but this is what I know.

Explanation:

At the boiling temperature, adding heat energy converts the liquid into a gas WITHOUT RAISING THE TEMPERATURE. In this case, the energy added to the liquid goes into breaking the bonds between the liquid molecules without causing the temperature to change. The same thing happens when a solid changes into liquid.

What is a crystal system?

A crystal system indicates many classes of crystals, space groups, and lattices. In crystallography terms,  crystal system and lattice system are associated with each other. The crystals based on their point groups are divided into seven crystal systems.

The seven-crystal system is the Cubic, Tetragonal, Hexagonal, Orthorhombic, Monoclinic, Triclinic, and Rhomohedral systems. The classification of Seven Crystal Systems is depending upon their lattice and atomic structure.

The size and length of their surfaces which are known as ‘faces’ and sides, and the angles between them, define the shapes of crystals. The cubic crystal system is the most symmetrical as all the angles and the length of the edges is equal.

While the triclinic is the most unsymmetrical crystal system as all the lengths and the angles between faces are unequal.

Which phrase describes non-foliated rocks?

have grains in parallel layers
include quartzite and marble
tend to split along their bands
form from crystallized magma

Answers

The answer is: Include quartzite and marble

Non-foliated rocks include quartzite and marble. Therefore, option (B) is correct.

What are the non-foliated rocks?

Nonfoliated rocks less foliated texture because they commonly lack platy minerals like micas. They often result from regional metamorphism. Examples include quartzite, marble, hornfel,  greenstone, and anthracite.

Marble is low to high-grade metamorphosed dolostone or limestone both of which are carbonate rocks, They are made of dolomite grains or interlocked calcite. Marble is very often carved in the artwork of palaces.

Quartzite is quartz sandstone that is medium to high-grade metamorphism. It is composed of interlocking grains of quartz and can be distinguished from sandstone because individual grains do not fall off during the rock is rubbed. Original sedimentary structures in quartzite will remain visible.

Which process begins the formation of sedimentary rock?

the movement of sediment
the cementation of rock sediment
the breakdown of rock into sediment
the buildup of sediment in one location

Answers

Answer:

Weathering breaks down pre-existing rock into particles, while erosion moves the particles to a site of deposition. These processes begin the formation of sedimentary rock.

Explanation:

Sediment is the term for the component that aids in the formation of sedimentary rock. All of the processes that lead to the sedimentation of organic and mineral particles are together referred to as sedimentation. The cementation of rock sediment forms sedimentary rock. The correct option is B.

What are sedimentary rock?

Sedimentary rocks are created by the material being deposited at the Earth's surface and then being cemented there by bodies of water. Existing rocks or pieces of extinct animals that have accumulated on the surface of the Earth over time generate sedimentary rocks.

Sediment is crushed and cemented as a result of deep sediment burial, creating sedimentary rock. The three types of sedimentary rocks are categorized as Organic, Clastic, and Chemical Sedimentary Rocks. Lime stone, clay, sandstone, etc. are some Sedimentary rocks.

The sediment particle size and fluctuation is the best indicator of the type of rock.

Thus the correct option is B.

On a hot summer day, air rises most quickly when it is above a desert. The correct option is C.

What is a desert?

A desert is a barren area of land with little precipitation and, as a result, hostile living conditions for plant and animal life.

The lack of vegetation exposes the ground's unprotected surface to denudation. Arid or semi-arid regions cover roughly one-third of the Earth's land surface.

Although the majority of deserts, such as the Sahara in North Africa and the deserts of the southwestern United States, Mexico, and Australia, occur at low latitudes.

Arid climates have less cloud cover than humid climates, and cloud tops reflect a significant amount of the sun's energy back into space, reducing surface heating. On a hot summer day, air rises the fastest above a desert.

Thus, the correct option is C.
