Chapter 6
magma- melted rock below Earth’s surface; called lava at the surface
Core- Earth’s innermost structure two views of the same thing
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 surface continental drift many animations
fault- a crack in the Earth’s crust where movement takes place
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
focus- the point inside Earth where an earthquake begins
epicenter- the point on Earth’s surface directly over the focus of an earthquake
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.link
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.link
dome mountain- one that forms when magma pushes up on Earth’s crust but does not break through
fault-block mountains- ones formed along fault lines where blocks of rock fall, are thrust up, or slide
fold mountains- ones that form where two plates collide and force layers of rock into folds notice the curvy shapes of rock layers
fossil- the physical remains or traces of a plant or animal that lived long ago
