Molton rock known as mantle magma, for the most part. There is also an iron core, the inner portion of which is probably solid.
Although the bottom of the lithosphere is also part of the mantle, the answer is the mantle.
The bottom part of the mantle is called the "lower mantle." It lies beneath the upper mantle and extends from about 670 kilometers to 2,900 kilometers below the Earth's surface. The lower mantle is composed of solid rock that is capable of flowing over long periods of time.
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
The upper mantle and the lower mantle.
The lower part of the mantle is called the mesosphere.
Yes, it is the top part of the Earth's mantle
The mantle is counted as the middle part of the earth
Yes, it is the top part of the Earth's mantle
The bottom part of the Earth's mantle is not molten because the extreme pressure at those depths increases the melting point of the rocks and minerals present. This means that even at high temperatures, the pressure prevents them from melting.
No, although a large part of the mantle forms the mesosphere, the upper brittle mantle is part of the lithosphere and the ductile layer of the mantle below this is formed of the asthenosphere. The mantle below the asthenosphere (i.e. that part from 700 km down to the core-mantle boundary is the mesosphere).
