Earth Science Review

What are oceanic trenches?

• Deep underwater canyons formed at convergent plate boundaries.

• Shallow areas of the ocean where sunlight penetrates.

• Regions of the ocean with high biodiversity and coral reefs.

• Flat plains on the ocean floor formed by sediment deposition.

What is the difference between weathering and erosion?

• Weathering is the movement of rocks, while erosion is the breaking down of those rocks.

• Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

• Weathering and erosion are the same processes that occur simultaneously.

• Weathering is the process of creating new rocks, while erosion is the process of destroying them.

What is a transform plate boundary?

• A boundary where two plates slide past each other.

• A boundary where two plates move away from each other.

• A boundary where two plates collide and form mountains.

• A boundary where one plate is forced under another.

What is deposition?

• The process by which water, ice, wind or gravity deposit rock sediments and soil in a new place.

• The process of eroding soil and rock from one location to another.

• The process of transforming liquid water into vapor in the atmosphere.

• The process of breaking down rocks into smaller pieces through weathering.

What elements make up the core of the Earth?

• Copper and Zinc

• Nickel and Iron

• Aluminum and Silicon

• Lead and Mercury

What is a fault?

• A type of rock formation that is solid and unbreakable.

• A fracture in the Earth's crust where blocks of rock have moved past each other.

• A volcanic eruption that causes the ground to shake.

• A layer of soil that is rich in nutrients.

What is a volcanic island arc?

• A chain of volcanic islands formed at convergent boundaries, typically where an oceanic plate subducts under another plate.

• A series of underwater mountains formed by tectonic activity.

• A type of island formed by erosion and sediment deposition.

• A landform created by the accumulation of coral reefs.

What geological feature is formed when crustal plates pull apart?

• Rift zones

• Mountain ranges

• Volcanic islands

• Ocean trenches

What is the process of subduction?

• The process where one tectonic plate moves under another and sinks into the mantle.

• The process of two tectonic plates colliding and forming mountains.

• The process where tectonic plates slide past each other without significant vertical movement.

• The process of tectonic plates moving apart and creating new crust.

What is the plastic layer of the mantle on which pieces of the lithosphere move?

• Asthenosphere

• Lithosphere

• Mesosphere

• Core
