Various types of rocks diagram are made for different purposes. While some are made for geologists who need to be able to keep a track of their discoveries and the types of rocks in the earth and on the ground, others are made for students who are taught about these types of rocks and the types of rocks diagram hence, differ for both groups. There are various types of rocks diagram would help understand. Since a lay man cannot dig into the earth to check out these types of rock diagram would help get a clearer picture instead.
Some types of rocks diagram show how when some rocks are pushed deep into the earth, they will melt into the magma. These rocks then become part of the magma until the magma is no longer able to sustain its fluid state, it will cool down and it would settle. After this these types of rocks diagram show that the magma then transitions to the igneous state. When exposed to other surroundings the magma, due to volcanic activity, would cool down very rapidly and become part of the earth’s soil. Basically these types of rocks diagram show that igneous rocks can be converted to magma and vice versa.
Then, types of rocks diagram also show that some rocks can transition to metamorphic. Metamorphic rocks are those that are physically and chemically altered to the extent that they form a different type of rock altogether. Sometimes rocks come into contact with igneous intrusion as a result of which they are chemically altered to form another type of rock. This is referred to as contact metamorphism- the rock changes its composition after coming into contact with an igneous rock. This is also how diamonds are formed and sometimes this can take place within specific regions due to which you would find a particular type of rock in some places.
The most visible and obvious types of rocks diagram show that there are also sedimentary rocks which are exposed to the surrounding atmosphere and can easily be broken down by the wind. These types of rocks carry dissolved minerals with them and enrich soil that they land on as a result. Sometimes these may be the product of larger rocks that are broken down to form smaller rocks. These are some of the most basic types of rocks diagram that would help students and geologists understand the different types of rocks that exist.
The thing about different types of rocks is that they are all formed in a particular way as a result of particular processes. While some become part of magma and then, become igneous rocks again, there are those that can be found on the surface of the earth which can be easily broken down by the wind. Then there are those that remain deep in the earth and cannot be discovered until and unless the earth in a particular area is excavated too. Diamonds are an example of these types of rocks .
