3 Types of Rocks
Storyboard Tekst
- Igneous Rocks
- The first rock we are talking about is igneous. Igneous rocks are formed by the solidification of magma.
- Hi there! We will be learning about the different types of rocks.
- Igneous Rocks
- Extrusive igneous rocks form when magma cools and solidifies above the Earth's crust.
- Igneous rocks are either intrusive or extrusive. Intrusive igneous rocks are formed when magma cools and solidifies under the Earth's crust.
- Sedimentary Rocks
- Next, we will talk about sedimentary rocks. These rocks are the most common type of rock on the Earth's surface.
- They are formed by the compaction of sediments. Sediments are loose materials like minerals and organic remains.
- Sedimentary Rocks
- Sedimentary rocks are known as the fossil rock. These rocks have different layers throughout the rock.
- Metamorphic Rocks
- Lastly, we will learn about metamorphic rocks. Metamorphic rocks are rocks that are made when a lot of heat and pressure act on another type of rock that changed it into a new form..
- Metamorphic Rocks
- Metamporphic rocks are known as the "changed rock" because they were originally a different rock that just changed into a new one.
- That is all! Thank you!
