Earth Science - Review I

The student should be able to label correctly a picture of the Earth, from inner core to crust, including the following: inner core, outer core, mantle, mesosphere, asthenosphere, lithosphere, Moho, crust.

The student should be able to answer the following questions:

How do we know that part of the inside of the Earth is liquid?
What is the composition of the mantle and core?
What is a continental plate?  How have they changed positions over time?
Give four explanations that support plate tectonic theory.
Name five kinds of volcanoes and explain the differences among them.
What types of materials do volcanoes release?
What is the difference between lava and magma?
What are convergence, divergence, and subduction?
What is elastic rebound theory?
What is the difference between primary waves and secondary waves?
Explain how a seismograph works.

The student should be able to reproduce the geologic column and label it correctly, explaining how radioactive decay helps determine numerical age of rock strata.

Earth Science - Earthquakes - Causes

Earthquakes and Volcanoes by Lin Sutherland and Thomas Wright

Vocabulary Added:
elastic rebound theory: idea that the removal of stress allows rocks to snap back to their original size and shape

Discussion:
Plate convergence
Plate movement along faults
Direction of plate movement (horizontal or vertical)

Activity:
Rubber band snapping - demonstrate elasticity and stored energy
