Rocks There are 3 types of rocks. Igneous, metamorphic and  sedimentary. Some rocks have air bubbles because  of the way they are formed.  Rocks such as Millstone Grit have  these properties and are otherwise  known as Sedimentary Rocks Other rocks don’t have air bubbles,  these tend to have crystals Crystals have a more jagged form  (meaning they fit together more  easily) This means there’s less air bubbles  therefore its a denser rock Metamorphic and Igneous rocks  have these properties.

Metamorphic Metamorphism means  "changed form".  The Changes occur  because of:  Heat  Pressure

How metamorphic rocks change Say a sedimentary rock is pushed down towards the earth’s mantle The magma heats it up and changes its structure Also the pressure can take part in this process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
