Fossils are found in sedimentary rock. Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens. Metamorphic rocks are formed under the surface of the earth form metamorphosis(change) that occurs due to intense heat and pressure (squeezing). Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material.

The layers of earth are the crust, mantle, outer core and inner core. The portion of Earth underneath the crust contains the asthenosphere and the mesosphere is in the mantle. The outer layer of Earths crust is made up of huge pieces of rock called tectonic plates. The borders, or cracks, between tectonic plates are called faults. Tectonic plates move due to heated currents deep within Earth. Scientists believe that 250 million years ago that continents were connected. A tsunami is caused by tec...
