We learn about the rock that we have lived on, as a species, for just over 6,000 years. The Earth is made up of many layers that we are learning more about every week. Did you know that human made erosion is accelerating at an unprecedented pace? The Earth has a lot of cool things like geysers. These can be thought of as Earth's sweat glands. The only difference is that some geysers can shoot water at a pressure that is enough to tear your skin off.
Worksheets range from simple navigation of the ocean floor, underground water deposits, landforms, layers of Earth, hemispheres, and atmospheric layers.
