1A geologist is a person who studies the earth. Geologists study the structure of the Earth, or just how it is made, the origin, or the start of the Earth, and its history. Geologists study rocks, soil, fossils, mountains, and earthquakes.2Geologists research the structure of the Earth, and they have found that that is comprised of 4 main parts. The planet has a hard inner core, a liquid external core, a mantle, and also a crust. The late is the outer layer the the Earth, simply as bread tardy is ~ above the external of the bread slice. The crust has continents and also ocean basins. The is comprised of countless plates, or pieces, that move around. In ~ one time, every the continents to be joined with each other in one giant land mass. Scientists called this Pangea. There is scientific proof that the continents have actually joined together and also moved far from each other countless times throughout Earth"s history. The movement of these plates, although that happens really slowly, is what causes earthquakes. Some geologists examine earthquakes to help people by predicting when an earthquake can happen and also how come prepare for it. Periodically the plates push apart, and also sometimes they push together. When plates press together, mountains are formed. The Himalaya Mountains, the tallest hills on Earth, were created when two continental plates moved together and pushed up these an excellent mountains!3Also, by researching the framework of the Earth, geologists have actually helped us understand why there space volcanoes. Inside the Earth"s mantle, rock is under good pressure and heat, and it melts and also becomes magma.
