Semester 1 Final Exam Flashcard Review

Front

What causes mantle convection?

Back

An unequal distribution of heat in the mantle.

Front

What is ductile deformation?

Back

The type of deformation of rock in which it changes shape without breaking or fracturing.

Front

What type of mountains are formed by the collision of oceanic plates?

Back

Volcanic mountains.

Front

What process decreases the salinity of seawater?

Back

Precipitation.

Front

What is isostatic adjustment?

Back

The rise of the crust upwards in the mantle as erosion removes the tops of mountains.

Front

Define mantle convection.

Back

The movement of the mantle caused by the heat from the Earth's core, leading to tectonic plate movement.

Front

What is brittle deformation?

Back

The type of deformation where rocks break or fracture under stress.

Front

What are folded mountains?

Back

Mountains formed by the folding of Earth's crust due to tectonic forces.

Front

What is the role of evaporation in seawater salinity?

Back

Evaporation increases the salinity of seawater by removing water and leaving salts behind.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.
