Unit 5 Mini-Assessment

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle as the plates converge.

Front

What occurs at plate boundaries?

Back

Common occurrences at plate boundaries include earthquakes, volcanic activity, and the formation of mountain ranges.

Front

Define plate tectonics.

Back

Plate tectonics is the geological theory that describes the movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What is the process of cementation in sedimentary rock formation?

Back

Cementation is the process where dissolved minerals crystallize and glue particles of sediment together to form sedimentary rock.

Front

What is deposition in geology?

Back

Deposition is the geological process where materials are added to a landform or land mass, often through wind, water, or ice.

Front

What is the difference between erosion and weathering?

Back

Erosion is the process of moving soil and rock from one location to another, while weathering is the breaking down of rocks and minerals at their original location.

Front

What are deep-ocean trenches?

Back

Deep-ocean trenches are the deepest parts of the ocean, formed by the subduction of one tectonic plate beneath another.

Front

Explain sea-floor spreading.

Back

Sea-floor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away from the ridge.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Front

What causes earthquakes?

Back

Earthquakes are caused by the sudden release of energy in the Earth's crust, often due to the movement of tectonic plates.
