What is the mantle?

Back

The mantle is a thick layer of rock located between the Earth's crust and core, composed of silicate minerals and is involved in tectonic processes.

Front

What is convection in the mantle?

Back

Convection in the mantle refers to the movement of molten rock due to temperature differences, causing hot material to rise and cooler material to sink.

Front

What is chemical weathering?

Back

Chemical weathering is the process by which rocks are broken down by chemical reactions, altering their mineral composition.

Front

What is an example of chemical weathering?

Back

Dissolution, hydrolysis, and oxidation are examples of chemical weathering.

Front

What is exfoliation?

Back

Exfoliation is a physical weathering process where layers of rock peel away due to temperature changes, not a chemical process.

Front

What happens at tectonic plate boundaries?

Back

At tectonic plate boundaries, plates interact, which can lead to earthquakes, volcanic activity, and mountain formation.

Front

What is the role of magma in plate tectonics?

Back

Magma in the mantle causes convection currents that drive the movement of tectonic plates.

Front

How does a volcanic eruption affect the carbon cycle?

Back

A volcanic eruption increases the amount of carbon in the atmosphere, impacting the carbon cycle.

Front

What is the significance of density in plate interactions?

Back

The density of tectonic plates determines how they interact; denser plates may subduct beneath less dense plates.

Front

What is hydrolysis?

Back

Hydrolysis is a chemical weathering process where water reacts with minerals, leading to their breakdown.
