Igneous rocks are made from cooled magma. The colorthey are matters on how they cooled. If they cooled slowly,they would have a darker color and if they cooled quickly,they will be lighter colors. Igneous rocks are often shiny.Some igneous rocks can be dull and boring. The earth ismade up of igneous rock. Igneous rocks turn from liquidrock to solid rock. I hope you just learned a little moreabout igneous rocks!
Metamorphic rocks form deep in the earth where hightemperatures, great pressure, and chemical reactionscause one type of rock change into another type of rock.Metamorphic rocks begin at 12-16 kilometers beneath theearth’s surface. They begin the changing at temperatures100 degrees Celsius to 800 degrees Celsius. If yousqueeze and heat a rock for a few million years, it can forminto a whole new different kind of rock.
There are all kinds of different types of sedimentary rocks, here are some examples of some sedimentary rocks: Sandstone is formed from small grains of sand tightly pressed together. Sandstones are very common rocks. They are formed from the sand on beaches , riverbeds, and sand dunes. Limestone are formed by tiny shells from the dead sea animals that have been cemented together. Conglomerate contains sand and rounded pebbles that have also been cemented together. Shale is formed in the water. They may be formed in swamps or in bogs. You will know when you see a sedimentary rock because you can see the layers in it. Sedimentary rocks are my favorite kinds of rocks!
