CH 5 MAJOR DOMAINDS OF THE EARTH

The mantle in liquid state due to its pressure and high temperatures. Explanation: Earth’s mantle is located under the earth the crust of the planet and is entirely made of the liquid magma and in the form of solid rock.

The Earth’s mantle is mostly solid from the liquid outer core to the crust, but it can creep on the long-term, which surely strengthens the misconception of a liquid mantle. Courtesy of the U.S. Geological Society.

It is mostly solid rock, but less viscous at tectonic plate boundaries and mantle plumes. Mantle rocks there are soft and able to move plastically (over the course of millions of years) at great depth and pressure. The transfer of heat and material in the mantle helps determine the landscape of Earth.

Some of the rock types that are common in the mantle include olivine, peridotite, pyroxene, and garnet. The mantle is denser than the crust but much less dense than Earth’s core, which is a huge ball of hot metal, mostly iron and nicke

The mantle is the mostly-solid bulk of Earth’s interior. The mantle lies between Earth’s dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth’s total volume

he four spheres of Earth are closely connected to each other. Birds(biosphere) fly through the air (atmosphere), water (hydrosphere) flows through the soil (lithosphere). The spheres of earth are closely connected to each other. A change in one sphere results in change in two or more spheres.

All of the oceans, lakes, seas and clouds are an example of the hydrosphere. All the waters of the Earth, as distinguished from the land and the gases of the atmosphere.

The geosphere is all of the rock, land and minerals on Earth, and you can remember this because ‘geo’ means ‘ground. ‘ The hydrosphere is all of the water on Earth, which makes sense since ‘hydro’ means ‘water. ‘ ‘Bio’ means ‘life,’ so all of the living organisms on Earth make up the biosphere.

The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet’s hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground—as groundwater, in wells and aquifers.

An atmosphere is the layers of gases surrounding a planet or other celestial body. Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
