Geologic Processes-2.2

Front

What is the Earth's inner core?

Back

The Earth's inner core is a solid sphere composed mainly of iron and nickel, located at the center of the Earth.

Front

What is the Earth's mantle?

Back

The Earth's mantle is a thick layer of semi-solid rock located between the crust and the outer core, responsible for tectonic activity.

Front

What are the three types of plate boundaries?

Back

Convergent, Divergent, and Transform.

Front

What occurs at a convergent boundary?

Back

At a convergent boundary, two tectonic plates collide, which can lead to the formation of mountains, earthquakes, and volcanic activity.

Front

What is a subduction zone?

Back

A subduction zone is an area where one tectonic plate is forced under another, often leading to volcanic eruptions.

Front

What is volcanic activity?

Back

Volcanic activity refers to the eruption of magma from beneath the Earth's crust, resulting in the formation of volcanoes.

Front

How does oceanic crust differ from continental crust?

Back

Oceanic crust is denser and thinner than continental crust, which is thicker and less dense.

Front

What happens when an oceanic plate collides with a continental plate?

Back

The denser oceanic plate is forced under the continental plate, leading to melting and volcanic activity.

Front

What is the role of magma in volcanic eruptions?

Back

Magma rises to the surface during volcanic eruptions, causing lava flows and explosive eruptions.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other, often causing earthquakes.
