Rock cycle

Question 1

Igeneous rock

Answer 1

one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet’s mantle or crust.

Question 2

seditmentary rock

Answer 2

types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth’s surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.

Question 3

metamorphic rock

Answer 3

arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure, causing profound physical or chemical changes.

Question 4

Crystallization

Answer 4

is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.

Question 5

Lithification

Answer 5

is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock. Essentially, lithification is a process of porosity destruction through compaction and cementation

Question 6

Seditment

Answer 6

matter that settles to the bottom of a liquid; dregs.

Question 7

Deposition

Answer 7

the action of deposing someone, especially a monarch.

Question 8

Weathering

Answer 8

the process of wearing or being worn by long exposure to the atmosphere.

Question 9

Erosion

Answer 9

the process of eroding or being eroded by wind, water, or other natural agents.
