Front

What type of energy is released during earthquakes and travels through the Earth?

Back

Seismic waves.

Front

How do seismic waves behave as they travel through different layers of the Earth?

Back

Seismic waves will change speed and direction when they go through different layers.

Front

What are seismic waves?

Back

Waves of energy that travel through the Earth, produced by earthquakes or other geological activity.

Front

What is the difference between P-waves and S-waves?

Back

P-waves (primary waves) are compressional and can travel through solids and liquids, while S-waves (secondary waves) are shear waves and can only travel through solids.

Front

What role do volcanic rocks play in understanding the Earth's interior?

Back

Volcanic rocks provide surface evidence of the materials that make up the Earth's interior.

Front

What is the Earth's magnetic field and how is it related to its interior?

Back

The Earth's magnetic field is generated by the movement of molten iron in the outer core, providing insights into the core's composition.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer beneath the lithosphere that allows tectonic plates to move.
