Front

What is the term for the process where one tectonic plate slides beneath another?

Back

Subduction

Front

What geological feature is formed when two tectonic plates move apart?

Back

Mid-Ocean Ridges

Front

What is the process called that creates new oceanic crust at mid-ocean ridges?

Back

Sea Floor Spreading

Front

What are the primary components of the Earth's outer core?

Back

Liquid iron and nickel

Front

What is the significance of mid-ocean ridges in plate tectonics?

Back

They are sites of new crust formation and volcanic activity.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner and denser than continental crust.

Front

What geological activity is commonly associated with subduction zones?

Back

Earthquakes and volcanic eruptions.

Front

How does sea floor spreading contribute to plate tectonics?

Back

It pushes tectonic plates apart, leading to the movement of continents.

Front

What is the role of the mantle in Earth's geology?

Back

It is the layer between the crust and outer core, involved in convection currents.
