Serie : Earth and Space (28 min)
The planet Earth is constantly changing. This program focuses on what the planet Earth is made of inside and out (crust, lava, magma). The planet is made of different types of rock: igneous, sedimentary, and metamorphic. Wind, water and weather tear down the surface of the land creating earthquakes, tidal waves, physical and chemical weathering, volcanoes, erosion, acid rain, mountain formation.
This program shows different types of shores and the effect it has in our daily lives as well as the theory of plate tectonics.
