Earth and Space Science

Earth and space science is covered. Guests explain concepts of geology, meteorology, astronomy, biology, and earth science. Among the topics are: the formation of life on earth, earthquakes and plate tectonics, the rock cycle, the water cycle, pollution, weather patterns and climate, and renewable and non-renewable energy sources. The Rock Cycle looks at what has happened on earth and what likely will happen. The form that rocks take reflects a point in time and can be transformed from earth's interior to mantle to magma to igneous rock to sediment to sedimentary rock to metamorphic rock. Also: seismologists' ability to predict where, but not when, earthquakes will occur; and a diagram of the water cycle to demonstrate the importance of knowing how to read graphics on the GED exam.
