The lower mantle has a significantly higher density than the upper The Earth's lower mantle is the largest part of the mantle at 1,400 miles thick, and is made of dense rock so hot it exists almost in liquid form. The upper mantle and crust (outermost layer) together, make up the lithosphere. According to a team of researchers led by planetary scientist Junjie Dong of Harvard University, minerals deep inside the mantle slowly drunk up ancient Earth's oceans to leave what we have today. It has different temperatures at different depths.

The lower mantle, or lower mesosphere, is one of the three main layers that make up the Earth, along with the upper mantle and the Earth's core. The highest temperatures occur where the mantle material is in contact with the heat-producing core. Introduction [2] The accurate knowledge of the chemical composition of the mantle is a foundation for many geophysical and geochemical models. The mantle is a secrete shell. The main purpose of a mantle is to carry out the plan of God on earth for that generation; to bring about His desire for His people. The mantle is the mostly-solid bulk of Earth's interior. Earth's mantle is thought to be composed mainly of olivine-rich rock. The mantle is just a name we humans gave to a portion of the interior of the earth. The mantle serves the role of the repository of most of the earth's mass, and is one of the reservoirs in the rock cycle (and water and carbon and nitrogen and whatever cycle you want to consider). Lower mantle. When the Earth was young, the majority of the mantle would have been viscous melted rock, but this has cooled and solidified over millions of years to form the mantle we know today. Here, we calculated the water storage capacity in Earths solid mantle as a function of mantle temperature. 1. The temperature is lowest immediately beneath the crust and increases with depth. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earths total volume. It contains about 56% of the total volume filling in the transition zone and upper core. It can serve as a strong guideline as well as constraints when we try to quantify Earth accretion processes and subsequent global differentiation processes such as core segregation and crustmantle differentiation. "We calculated the water storage capacity in Earth's solid mantle as a function of mantle temperature," the researchers wrote in their paper. The functions of the mantle is to protect the crab. The mantle doesn't have a design function, it simply is. The mantle makes up 84 percent of the Earths volume, and consists of both solid and molten rock known as magma. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. We find that water storage capacity in a hot, early mantle The lower mantle (670-2900 km) represents a significant amount of volume of Earth.
