12/06: Earth's Interior Questions

Front

What are compressional waves?

Back

Compressional waves, also known as P-waves, are seismic waves that move in a push-pull motion, compressing and expanding the material they travel through.

Front

What are shear waves?

Back

Shear waves, also known as S-waves, are seismic waves that move perpendicular to the direction of wave propagation, causing the material to shear or deform.

Front

What is a tsunami?

Back

A tsunami is a series of ocean waves caused by large underwater disturbances, such as earthquakes, volcanic eruptions, or landslides.

Front

What should residents do when a tsunami warning is issued?

Back

Residents should evacuate to higher ground to avoid the risk of flooding and potential loss of life.

Front

What is the relationship between earthquakes and plate boundaries?

Back

Most earthquakes occur along plate boundaries where tectonic plates interact, leading to stress accumulation and release.

Front

How is density calculated?

Back

Front

What is the significance of earthquake epicenters?

Back

Earthquake epicenters are the points on the Earth's surface directly above where an earthquake originates, indicating areas of seismic activity.

Front

What are the effects of underwater earthquakes on coastal areas?

Back

Underwater earthquakes can generate tsunamis that lead to severe destruction in coastal areas, including flooding and damage to infrastructure.

Front

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

Back

P-waves (compressional waves) travel faster and can move through solids and liquids, while S-waves (shear waves) only travel through solids and are slower.

Front

What is the role of seismic waves in understanding Earth's interior?

Back

Seismic waves help scientists infer the composition and state of Earth's interior by analyzing how these waves travel through different materials.
