Earth and Space

1.It is a volcano that has had at least one eruption during the past 10,000 years.

2.It is what happens when two blocks of the earth suddenly slip past one another.

3.Typically are thousands of kilometers long and hundreds of kilometers across and parallel continental coastlines, usually located near plate boundaries.

4.It is the theory that Earth's crust is broken up into plates.

5.These plates are actually pieces of the planet's lithosphere, which is the outermost shell of the earth made up of the earth's crust and upper part of the mantle.

6.They are Earth scientists, specialized in geophysics, who study the genesis and the propagation of seismic waves in geological materials.

7.It is an instrument for measuring earthquake (seismic) waves.

8.These are the waves of energy caused by the sudden breaking of rock within the earth or an explosion.

9. Seismic waves that can pass through solids and liquids, so they are present on the other side of the Earth’s liquid core.

10.Seismic waves that can only pass through solids, so they cannot pass through the core.
