It can vary from a few feet to hundreds of acres and from less than 1 to more than 100 feet deep. ______ 2. A tornado B. The Earth has a crust under the oceans and the land that we live on. This crust made of massive areas of flat rock called tectonic plates, which float on the Earth’s mantle, the inside layer of the Earth. When the plates move slowly together, this movement forces energy through the crusts to the Earth’s surface. The energy causes the Earth to tremble and shake. ______ 3. A hurricane C.
