mantle- the thick layer of Earth’s structure just below the crust

lithosphere-the shell formed from Earth’s solid upper mantle and
crust

crust- the thin, rocky outer layer of Earth
Although it looks thin compared to the other layers, there are plenty of things happening at the crust.

plate tectonics- the theory that giant plates of Earth’s crust and upper mantle are moving slowly
across Earth’s surfacecontinental drift
many animations

fault- a crack in the Earth’s crust where movement takes place
![Page 11: Chapter 6. magma- melted rock below Earth’s surface; called lava at the surface.](https://reader036.fdocuments.net/reader036/viewer/2022081501/56649cb85503460f9497e1d8/html5/thumbnails/11.jpg)
There are major fault lines at the boundaries of continental plates. The plates don’t always move in the same direction.
There are also faults in the U.S.

earthquake- a violent shaking of Earth’s crust as built-up energy is
released
![Page 13: Chapter 6. magma- melted rock below Earth’s surface; called lava at the surface.](https://reader036.fdocuments.net/reader036/viewer/2022081501/56649cb85503460f9497e1d8/html5/thumbnails/13.jpg)
focus- the point inside Earth where an earthquake begins
![Page 14: Chapter 6. magma- melted rock below Earth’s surface; called lava at the surface.](https://reader036.fdocuments.net/reader036/viewer/2022081501/56649cb85503460f9497e1d8/html5/thumbnails/14.jpg)
epicenter- the point on Earth’s surface directly over the focus of
an earthquake
![Page 15: Chapter 6. magma- melted rock below Earth’s surface; called lava at the surface.](https://reader036.fdocuments.net/reader036/viewer/2022081501/56649cb85503460f9497e1d8/html5/thumbnails/15.jpg)
seismic waves- waves of energy sent through Earth when parts of
the crust move suddenly during an earthquake
Here’s a link to a model that shows how waves can move. Go to the mighty wave maker.

When the Earth’s plates move but not in a sudden movement
(earthquake), mountains can form.Here’s a link to explain it a bit
further.

dome mountain- one that forms when magma pushes up on Earth’s crust but does not break through
![Page 18: Chapter 6. magma- melted rock below Earth’s surface; called lava at the surface.](https://reader036.fdocuments.net/reader036/viewer/2022081501/56649cb85503460f9497e1d8/html5/thumbnails/18.jpg)
fault-block mountains- ones formed along fault lines where
blocks of rock fall, are thrust up, or slide
![Page 19: Chapter 6. magma- melted rock below Earth’s surface; called lava at the surface.](https://reader036.fdocuments.net/reader036/viewer/2022081501/56649cb85503460f9497e1d8/html5/thumbnails/19.jpg)
fold mountains- ones that form where two plates collide and force
layers of rock into folds
notice the curvy shapes of rock layers

lived long ago
