• Igneous, sedimentary and metamorphic rocks explained ...

    What are igneous, sedimentary and metamorphic rocks? Rocks are made up of different minerals and form the Earth's crust (outer layer). Different combinations of minerals form rocks; minerals are made of elements. There are 3 different types of rocks; igneous, sedimentary and metamorphic. Igneous rock is formed when magma or lava from volcanoes cools. Examples include basalt and granite.

  • Geologic Age Dating Explained Kids Discover

    Sep 30, 2014· To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition. This rule is common sense, but it serves as a powerful reference point.

    Clastic sedimentary rocks form by weathering processes which break down rocks into pebble, sand, or clay particles by exposure to wind, ice, and water. Clastic and nonclastic sedimentary rocks are the only members of the rock family that contain fossils as well as indicators of the climate (ripple marks, mudcracks and raindrops) that was present when the rock was formed.
