Geology is the study of the Earth's solid components, including the types of rocks and the processes that change them, which are classified as igneous, metamorphic, and sedimentary. Sand is formed from finely crushed particles of rocks and minerals, while diamonds are formed from highly pressurized rocks that are polished and cut. The document provides fundamental definitions and classifications within the field of geology.

1. What is Geology?

2. Definition of Geology
Geology is an earth science
comprising the study of solid
Earth, the rocks of which it is
composed, and the processes by
which they change

3. Types of Rocks
Igneous
Metamorphic
Sedimentary

4. Igneous
Formed through the
cooling and
solidification of magma
or lava

5. Metamorphic
Formed by changes in
heat, pressure, or
chemical conditions

6. Sedimentary
Formed by the
deposition of
material at the
earth’s surface and
within bodies of
water

7. How is sand formed?
Sand is finely crushed
particles of rocks and
minerals

8. Diamonds are Rocks Too!
Diamonds are highly
pressurized rocks that
are polished and cut to
perfection
