Science 8 Earth's interior and plate tectonics review

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface.

Front

How do scientists study magma?

Back

Scientists study lava samples from volcanoes.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, generated by earthquakes and volcanic activity.

Front

How do we know what is inside the Earth?

Back

We know what is inside the Earth by analyzing seismic waves from earthquakes and volcanoes.

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, composed of solid rock.

Front

What is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the core, composed of semi-solid rock.

Front

What is the core of the Earth?

Back

The core is the innermost layer of the Earth, consisting of a solid inner core and a liquid outer core.

Front

What type of plate interaction causes the formation of deep ocean trenches?

Back

Convergent plate interactions cause the formation of deep ocean trenches.

Front

What is plate tectonics?

Back

Plate tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What are divergent boundaries?

Back

Divergent boundaries are areas where tectonic plates move apart, often creating new crust.
