What is the lithosphere?

The lithosphere includes the crust and upper part of the mantle, and is made up of tectonic plates that are less dense than the mantle.

How are seismic waves used to study the Earth's structure?

The Earth's crust is too thick to drill through so scientists use seismic waves to study the Earth's structure. They are produced by earthquakes. By the time it takes for these waves to travel through the Earth, and where they are detected, scientists can draw conclusions about the structure of the Earth.



Where can S-waves travel?

S-waves can only travel through solids (mantle).

Where can P-waves travel?

P-waves can travel through solids and liquids.

Is the type of volcanic eruption linked to the composition of the lava?

Yes

Explain how geologists study volcanoes and predict when they erupt

Geologists study volcanoes to try to find out if their are signs that a volcanic eruption might happen soon - things like magma movement below the ground near a volcano.

How does being able to spot theses kinds of clues help us?

Being able to spot these kinds of clues means that scientists can predict eruptions with a much greater accuracy than they could in the past.


Volcanoes are are very unpredictable. Scientists will only be able to say that an eruption is more likely than normal but not that it's certain. Even knowing this save lives.

Describe the mantle

The mantle has the properties of a solid, but can flow very slowly.
