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 arise from the transformation of existing rock to new types of rock, in a process called metamorphism.

Question 4

Crystallization

Answer 4

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

Lithification is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock.

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

The geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

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, atmospheric gases, and biological organisms.

Question 9

Erosion

Answer 9

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.
