The three different types of rocks we have on earth are metamorphic rocks, igneous rocks, and sedimentary rocks. Metamorphic rocks are rocks that were once a different type of rock but due to heat, time, and pressure transformed into another type. Igneous rocks are formed through the cooling of magma or lava. Sedimentary rocks are fragments of other rocks transported to water. The following are examples of each of these types of rocks.
This is an example of marble. Marble is a metamorphic rock formed from limestone.
This is a piece of obsidian rock. Obsidian is an igneous rock formed from the quick cooling of molten rock.
This is a sample of a breccia rock. Breccia is a sedimentary rock made up of angular pebbles cemented together.
The following is an example of a soil texture diagram. This triangle is used to classify the types of soil. There are twelve types of soils that soil can be classified as.
All can be found on this link (Twelve Types of Soils).
