Metamorphic rocks are rocks that are shaped into another type of rock, by heat and pressure. Metamorphic rocks that change from one form to another. The word metamorphic means “to change”. Most of the earth’s crust is made up of metamorphic rocks. Metamorphic rocks have been changed over time by extreme pressure and heat. The background of this slide is metamorphic rock.

Igneous rocks is formed when a volcano erupts and lava comes out, then after a while it cools down and becomes igneous rock. Igneous rocks are the only type of rocks that form from molten magma. Igneous rock is the oldest of all rocks. Igneous comes from a Greek word that means fire. All igneous rocks do not cool the same way. That is why they don’t look all the same. They don’t contain any fossils. The background of this rock is igneous.

The background of this slide is a image of sedimentary rock. Sedimentary rock is where igneous rocks are weathered and eroded. What is weathered and eroded you ask? Weathered takes place when rocks are broken down into small particles or pieces by weather. On the other hand eroded means worn away by water or ice. Sedimentary rocks are formed, and sediments are pressed and cemented together to form sedimentary rocks.

Here is some more information about the rock cycle. Rock pieces, called sediments drop from the wind or water to make a layer. The layer can be buried under other layers. After a very long time, sediments can be cemented together to make sedimentary rock. (in this way, igneous rock can become sedimentary rock.) Metamorphic rock has the ability to form crystals. If it has crystals already, it forms bigger crystals. This rock changes, it is called metamorphic. This rock forms when lava cools and makes really pretty crystals. Magma is hot liquid stuff that comes out of volcanoes, this rock is called igneous rock.

A- sometimes B- Never Stops C- Once a year D- None of the above

Metamorphic rocks are rocks that are shaped into another type of rock, by cooling down? A- False B- True
