OTHER NOTES ON EARTH’S CHANGING SURFACE
WRITE ON THE RIGHT SIDE
Things you should know for the test!!!!
SLOW VS RAPID CHANGES
 Some changes to Earth’s surface occur
quickly or rapidly. An example of a
rapid change is an earthquake.
 Some changes occur over long periods
of time (slow changes). Examples of
slow changes are mountain building,
sea-floor spreading, and the formation
of trenches
OTHER NOTES (FOR THE TEST)
 Heat from the core creates convection currents in the mantle.
 Two opposing magma convection cells can pull one tectonic
plate below another.
 Earth’s source of energy that moves the tectonic plates is the
Earth’s molten layers.
 Earthquakes occur most commonly along cracks or boundaries
in Earth’s crust.
REVIEW QUESTIONS
1. What is the theory of plate tectonics and what is some
evidence to support it?
2. What is the following a picture of (be specific)?
3. What type of heat transfer takes place in the mantle?
4. Why does the Earth’s rigid crust float on top of the mantle?
5. Which portion of the Earth contains plates, which move to
form mountains and volcanoes?
6. Do mid ocean ridges form when plates move towards or
away from each other?
