Summary: Researchers discovered new details on how the earths crust is tearing up Ethiopia. It is said that one day a new ocean will emerge from the split. The surface of the earth is broken up into many tectonic plates which collide and move creating earthquakes, volcanoes and other natural disasters. The tectonic plates are created by magma which comes from the inside core and then reaches the ocean and solidifies creating a crust known as the oceanic crust. The speed of waves that travel through the crust is what lets the scientists know how thin the crust is. In Ethiopia the crust is so thin that the ground has fallen below sea level. Volcanoes around the area erupt because of constant stretching and thinning of the crust.

Approach: The scientists set off explosive charges in order to find out how thin the crust below them was. This is an example of Hypothesis Science because the scientists are saying what they believe is going to happen.

Importance: Because of this finding, now humans that live in Ethiopa, or close to the area that will supposedly split up, will have more precaution and will probably want to move to a different place in the world. :)
