What is dynamic metamorphism?

Back

Dynamic metamorphism refers to the changes in the mineralogy and texture of rocks due to high pressure and temperature conditions, typically occurring at convergent plate boundaries.

Front

Where is dynamic metamorphism most commonly found?

Back

Dynamic metamorphism is common at convergent, divergent, and transform plate boundaries.

Which type of crust will never undergo subduction?

Back

Continental crust will never go into subduction.

How does the energy released during earthquakes change with magnitude?

Back

The energy released during a magnitude 3 earthquake is approximately 900 times less than that of a magnitude 5 earthquake.

What happens to rocks at high temperature and low confining pressure?

Back

Rocks are more likely to bend rather than break under high temperature and low confining pressure.

Front

What is fractional crystallization?

Back

Fractional crystallization is the process by which different minerals crystallize from magma at different temperatures, leading to changes in the composition of the remaining liquid.

Front

What happens to magma during fractional crystallization?

Back

The remaining magma becomes more felsic and siliceous.

Front

What is the difference between felsic and mafic rocks?

Back

Felsic rocks are rich in silica and light-colored, while mafic rocks are rich in magnesium and iron and are darker in color.

Front

What is the significance of plate tectonics in geology?

Back

Plate tectonics explains the movement of Earth's lithosphere, leading to geological phenomena such as earthquakes, volcanic activity, and mountain building.

Front

What is subduction?

Back

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