Plate Tectonics & Weathering/erosion Review 2025

Front

What causes tectonic plate movement?

Back

Convection currents in the asthenosphere.

Front

What is a Divergent Plate boundary?

Back

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

Front

What type of mechanical weathering is caused by animals?

Back

Animal action.

Front

How were the Himalayan mountains formed?

Back

By two continental plates converging.

Front

What are tectonic plates?

Back

The pieces of the lithosphere that are being moved by convection currents.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates pull apart.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by natural processes.

Front

What is weathering?

Back

The breaking down of rocks and minerals into smaller pieces by natural forces.

Front

What is the asthenosphere?

Back

The semi-fluid layer of the Earth's mantle that allows tectonic plates to move.

Front

What is a transform fault boundary?

Back

A boundary where two tectonic plates slide past each other.
