The Lithosphere

Front

What is the lithosphere?

Back

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

Front

What are the two types of crust in the Earth's layers?

Back

Continental crust and oceanic crust.

Front

What is the main location where most earthquakes occur?

Back

Most earthquakes occur at plate boundaries.

Front

Which type of wave produced by an earthquake is the most destructive?

Back

S Waves (Secondary Waves) are the most destructive type of seismic wave.

Front

How did the Himalaya Mountains form?

Back

The Himalaya Mountains formed due to the collision of tectonic plates.

Front

What is soil composition?

Back

Soil composition refers to the proportions of sand, silt, and clay in the soil.

Front

What is the difference between sand, silt, and clay?

Back

Sand has larger particles, silt has medium-sized particles, and clay has the smallest particles.

Front

What is a tectonic plate?

Back

A tectonic plate is a massive slab of solid rock that makes up the Earth's lithosphere.

Front

What is the theory of plate tectonics?

Back

The theory of plate tectonics states that the Earth's lithosphere is divided into plates that move over the asthenosphere.

Front

What are P waves?

Back

P waves (Primary Waves) are the fastest seismic waves and can travel through solids and liquids.
