The bottom part of the mantle is not molten primarily due to the immense pressure exerted by the overlying layers of the Earth. This pressure raises the melting point of the mantle materials, causing them to remain solid despite the high temperatures. Additionally, the mantle is composed of silicate minerals that have high melting points, which further contributes to its solid state in the lower mantle.
What else can I help you with?
The earths volume is made up of what?
Molton rock known as mantle magma, for the most part. There is also an iron core, the inner portion of which is probably solid.
This solid layer is found between the inner core and the lithosphere?
Although the bottom of the lithosphere is also part of the mantle, the answer is the mantle.
What is the bottom part of the mantle called?
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.
What is the name of the lower part of mantle and the upper part of mantle?
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 strong lower part of the mantle between the asthenosphere and the outer core?
The lower part of the mantle is called the mesosphere.
What are the part of the mantle?
The upper mantle and the lower mantle.
Why isn't the bottom part of the earth's mantle molten?
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.
Is lithosphere part of the mantle?
Yes, it is the top part of the Earth's mantle
What part is the earths mantle?
The mantle is counted as the middle part of the earth
Is lithosphere part of mantle?
Yes, it is the top part of the Earth's mantle
Is the Asthenosphere the bottom part of the mantle?
Yes it is and the lithosphere is the upper part, to remember this think of L.A. The L comes first which is the lithosphere and the A comes second which is the asthenosphere
Is the mesosphere the same as the mantle?
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).
