Plate Tectonics and Earth's Layers

Front

What is the definition of a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often resulting in one plate being forced beneath the other.

Front

What was Pangaea?

Back

Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all the continents were joined together.

Front

List the layers of the Earth in order from the innermost to the outermost.

Back

The correct order of Earth's layers from the inside out is: inner core, outer core, mantle, crust.

Front

What is a plate boundary?

Back

A plate boundary is the region where two tectonic plates meet.

Front

Which of the following is NOT a tectonic boundary: convergent, divergent, or sedergent?

Back

Sedergent is NOT a tectonic boundary.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What is the mantle?

Back

The mantle is the thick layer of rock between the Earth's crust and outer core, making up about 84% of Earth's volume.

Front

What geological features are commonly associated with convergent boundaries?

Back

Geological features commonly associated with convergent boundaries include mountain ranges, deep ocean trenches, and volcanic arcs.

Front

What is the outer core composed of?

Back

The outer core is composed of liquid iron and nickel and is responsible for Earth's magnetic field.

Front

What happens at a transform boundary?

Back

At a transform boundary, two tectonic plates slide past each other horizontally, which can cause earthquakes.
