The next layer is the mesosphere, and rises about forty to fifty miles above the surface of earth the air is very thin in this layer and can reach temperatures as low as -184 degrees fahrenheit this layer is considered the middle atmosphere along with the troposphere. The structure of the earth is divided into layersthese layers are both physically and chemically different the earth has an outer solid layer called the crust, a highly viscous layer called the mantle, a liquid layer that is the outer part of the core, called the outer core, and a solid center called the inner core.

Summary: essay describes the different layers of the earth geology is the science of the study of the structures of the earth and the processes that affect those structures scientists who study the earth are known as ¡§geologists¡¨ one way geologists learn about the inner part of the earth is. The four main layers of the earth are the crust, mantle, outer core, and the inner core the planet earth was formed about 45 billion years ago, after the collapse of the supermassive gaseous body. The ozone layer is important to life on earth because it shields living things from uv rays constant change and state of flux on earth is caused by slow moving convection currents in the mantle the internal heat of earth is a result of heat from radioactive decay of certain elements.
The earth is made of three layers that are just like an onion - the crust, the mantle and the core some of these layers have even more layers in them and are always moving the earth is mostly made of rock and metal. After completing this lesson, you will be able to describe the layers of the earth's atmosphere, what they contain, and the components (gases) that make up the atmosphere. The layer of the atmosphere closest to the earth is the troposphere it begins at the surface of the earth and extends out to about 4 to 12 miles (6 to 20 km) this layer is known as the lower atmosphere. The crust is the first and upper most layer of the earth there is continental crust which sits on top of oceanic crust this layer is made frequently from granite rocks and is solid.
