3.1. Types of rocks
3.1.1. Igneous Rocks

3.1.2. Sedimentary Rocks
3.1.2.1. sandstone and limestone

3.1.3. Metamorphic Rocks
3.1.3.1. marble and slate

3.2. How are rocks formed?
3.2.1. Sedimentary Rocks
3.2.1.1. Sedimentary rocks are formed from multiple layers of solid particles and dissolved minerals over thousands of years in the ocean.
3.2.2. Metamorphic Rocks
3.2.2.1. Sedimentary rocks are turned into metamorphic rocks by the extreme pressures and temperatures deep within the earth.
3.2.3. Igneous Rocks
3.2.3.1. Magma is a type of molten rock found deep underground. Occasionaly magma rises up through the earth's surface, causing volcanic eruptions. Igneous rocks are formed when it cools and solidifies.
