Course Organizer

This course has an over-arching theme of interdependence and covers three distinct areas of science: Life Science—Watersheds and Estuaries, Earth Science—Earthquakes and Volcanoes, and Physical Science—Hydroelectricity.

The earth is moving and changing at all times. It is building up and wearing away in a constant and ongoing process.

The earth’s surface is composed of rigid plates of solid material that move on the semi-molten mantle. Earthquakes and volcanoes occur at the boundaries between plates. New material is formed when plates spread, allowing magma to ooze between. Plates shrink when sub-duction occurs.

Acid rain occurs when water combines with carbon dioxide in the atmosphere. It is most often caused by automobile and industrial pollution. It wears away the earth’s crust by breaking it down through a process known as chemical weathering.
