Rock Cycle

Question 1

Igneous rock

Answer 1

Igneous rock is formed through the cooling and solidification of magma or lava.

Question 2

Sedimentary rock

Answer 2

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth’s surface, followed by cementation.

Question 3

Metamorphic rock

Answer 3

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Question 4

Crystallization

Answer 4

Crystallization is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal.

Question 5

Lithification

Answer 5

Essentially, lithification is a process of porosity destruction through compaction and cementation.

Question 6

Sediment

Answer 6

Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

Question 7

Deposition

Answer 7

Deposition is the geological process in which sediments, soil and rocks are added to a land-form or landmass.

Question 8

Weathering

Answer 8

Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with water, and atmospheric gases.

Question 9

Erosion

Answer 9

In earth science, erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth’s crust, and then transports it to another location.
