Front

What layer of the Earth is responsible for tectonic plate movement?

Front

What is the state of matter of the inner core?

Back

The inner core is solid due to the immense pressure.

Front

What is the state of matter of the outer core?

Back

The outer core is liquid.

Front

What is the layer of the Earth that lies just below the crust?

Back

The layer that lies just below the crust is the mantle.

Front

What is the term for the semi-fluid layer of the mantle?

Back

The semi-fluid layer of the mantle is called the asthenosphere.

Front

What is the layer of the Earth that contains convection currents?

Back

Convection currents are found in the mantle.

Front

What is the difference between the lithosphere and asthenosphere?

Back

The lithosphere is the rigid outer layer of the Earth, while the asthenosphere is the semi-fluid layer beneath it.

Front

What is the approximate temperature of the inner core?

Back

The temperature of the inner core is estimated to be around 5,000 to 7,000 degrees Celsius.
