The structure of Earth can be defined in two ways: by mechanical properties such as rheology, or chemically. Mechanically, it can be divided into lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core. Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core.
The internal structure of the Earth is made up of the asthenosphere, the upper mantle, the lower mantle, the outer core and the inner core. These structures support the crust of the Earth. The asthenosphere is a semisolid layer of hot rock that's found at the top of the upper mantle.
The external structures of animals protect the animal from harm to internal organs. An example of an external structure is the skin and fur on a bear.
The structure of the Earth is divided into layers. These 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.

A knowledge of earth's interior is essential for understanding plate tectonics. A good analogy for teaching about earth's interior is a piece of fruit with a large pit such as a peach or a plum. Most students are familiar with these fruits and have seen them cut in half. In addition, the sizes of ...

Earth's interior, like that of the other terrestrial planets, is divided into layers by their chemical or physical (rheological) properties. The outer layer is a chemically distinct silicate solid crust, which is underlain by a highly viscous solid mantle.
Various external forces affect the earth's surface, such as different climates and the amount of rainfall. Freezing, thawing, and running water all contribute to weathering and erosion, processes that break rock down into tiny particles.These particles are then transported by water, ice, or wind as sediment. The processes of erosion reduce mountains to hills, create canyons, valleys, and soils...
