Rocks are classified into three
They're everywhere, they're free
These 3 types of rocks,
It forms our Earth's crust.
Igneous Rocks
When Volcanoes Erupt
When lava cooled and stops
It became volcanic rocks
Made of lithified sediments,
Which Geologists experiments
Just like muds we played
Sedimentary Rocks is named
Extreme temperature and pressure
A type of rock that we treasure
Metamorphic Rocks is here, present!
Marble is example said my professor.
