SOLAR SYSTEM

Detailed explanation-1: -The mesosphere is beneath the asthenosphere. It encompasses the lower mantle, where material still flows but at a much slower rate than the asthenosphere. A layer of liquid iron and nickel (and other elements) beneath the mesosphere.

Detailed explanation-2: -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 percent of Earth’s total volume.

Detailed explanation-3: -Altogether, the mantle is Earth’s thickest layer, with an average radius of around 1800 miles-though, again, this varies by location. The mantle comprises mostly solid rock, and most of those rocks are silicon-oxygen compounds known as silicates.

Detailed explanation-4: -The asthenosphere is where the mantle turns much more fluid and flows, allowing the above lying tectonic plates to drift across Earth. The deepest part of the mantle is the mesosphere where temperatures and pressures get so high that the rock becomes more rigid and doesn’t flow as easily.

Detailed explanation-5: -The lower part of the mantle where rock is very highly compressed is called the mesosphere. It is located from the core-mantle boundary to a depth of about 350 km. The pressure in the mesosphere is so great that even though the rock is hot, it is solid and considerably more rigid than the rock on top of it.
