Front

What layers of Earth are included in the lithosphere?

Back

The lithosphere includes the crust and upper mantle.

Front

How do scientists study the interior of the Earth?

Back

Scientists study the movement of seismic waves below the Earth's surface.

Front

What is the outer core of the Earth?

Back

The outer core is located between the lower mantle and the inner core.

Front

What causes volcanoes to erupt?

Back

The pressure of convection currents moving plates forces the eruption.

Front

What is a feature of a divergent boundary?

Back

Seafloor spreading.

Front

What is the definition of the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, often caused by earthquakes.

Front

What is the role of convection currents in the Earth's mantle?

Back

Convection currents in the mantle drive the movement of tectonic plates.

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid, while the outer core is liquid.

Front

What geological feature is formed at a convergent boundary?

Back

Mountain ranges and deep ocean trenches.
