Geology

From Simple English Wikipedia, the free encyclopedia

Geology is the study of the (nonliving) Earth (living things go in zoology, life science, etc.). Geologists, the people that study geology, want to know what types of rock the earth is made of. They also look at the Earth's land and rocks to learn more about its history. From this data they can observe past events in the Earth's history, like floods, volcanic eruptions, and earthquakes.

Geology has many subfields. Subfields are areas of study that are part of a larger area of study. Some subfields of geology are listed below:

• Hydrogeology - The study of water inside the Earth
• Volcanology - The study of volcanoes (and lava and magma) on land or under the ocean.
• Historical geology - Historical geologists use data to discover the history of the events that shaped the Earth.
