deposition
this rock is formed from solutions or sediments from older rocks
sedimentary rock
this rock is formed when magma or lava cools and hardens to become a solid

tectonic plates
a mixture of molten or semi-molten rock,volaties and solids that is found beneath the surface of the earth,and is expected to exist on other terrestrial planets and some natural satellies
magma
it is part of the earth is composed of a great variety of igneous,metamorphic,and sedimentary rocks
crust
the quality or condition of being hard
hardness
it is a naturally occuring substance,representableby a chemical formula, that is usually solid and inorganic
