ROCK CYLE!!!

Question 1

Igneous Rock

Answer 1

Igneous rocks are formed from the solidification of molten rock material. Some form below Earth’s surface. Some form on or above Earth’s surface. We describe these two basic types: Intrusive igneous rocks crystallize below Earth’s surface, and the slow cooling that occurs there allows large crystals to form.

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. Sedimentation is the collective name for processes that cause these particles to settle in place.

Question 3

Metamorphic Rock

Answer 3

Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture.

Question 4

Crystallization

Answer 4

Crystallization or crystallisation 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

Lithification (from the Ancient Greek word lithos meaning ‘rock’ and the Latin-derived suffix -ific) 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

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 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

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. Erosion is distinct from weathering which involves no movement.
