What is the Earth's inner core primarily composed of?

Back

The Earth's inner core is primarily composed of solid iron and nickel.

Front

Why is the Earth's inner core solid?

Back

The Earth's inner core is solid due to immense pressure.

Front

What are S waves?

Back

S waves, or secondary waves, are seismic waves that shake particles at right angles to their direction of travel.

Front

What is the primary characteristic of P waves?

Back

P waves, or primary waves, are seismic waves that travel faster than S waves and can move through solids, liquids, and gases.

What is a seismogram?

Back

A seismogram is a record produced by a seismograph that shows the arrival times of seismic waves.

Front

What is the difference between P waves and S waves?

Back

P waves are longitudinal waves that travel faster and can move through all states of matter, while S waves are transverse waves that travel slower and can only move through solids.

Front

What is the significance of the focus in an earthquake?

Back

The focus is the point within the Earth where an earthquake originates, and it is the source of seismic waves.
