The hot, soft rock from Earth's lower mantle is primarily composed of silicate minerals, such as perovskite and ferropericlase, which can deform and flow under extreme temperatures and pressures. This region, located about 670 to 2,900 kilometers beneath the Earth's surface, is characterized by high temperatures, estimated to range from 1,500 to 3,500 degrees Celsius. The soft nature of these rocks allows for convection currents that drive plate tectonics and influence geological processes on the Earth's surface.
What else can I help you with?
What are parts of the earths mantle?
The Earth's mantle consists mainly of the upper mantle and the lower mantle. The upper mantle is made up of solid rock, while the lower mantle is composed of more solid and dense rock. The mantle plays a crucial role in the movement of tectonic plates and the convection currents that drive plate tectonics.
What layer of rock that is 67 of earths mass is?
Mantle
What will happen if the flow of hot rock in earths mantle if the planets core eventually cools?
The flow of hot rock in earths mantle will stop and Earth's magnetic field will disappear
When solid rock in the earths mantle melts it forms a liquid rock known as?
Magma
Is the lower mantle rock stronger than the asthenosphere?
Yes, the lower mantle rock is typically stronger than the asthenosphere. The lower mantle exhibits solid-like behavior due to high pressure, while the asthenosphere is partially molten and represents a weaker layer of the Earth's mantle.

Earths middle layer?
The middle layer of the Earth is called the mantle. It is a region of solid rock that extends from the base of the crust to the outer core. The mantle is composed of silicate minerals and is divided into the upper mantle and the lower mantle.
Is rock found in earths mantle?
Yes.
Where would you be most likely to find granite in earths mantle or earths continents?
you will find it in earths mantle because it is a kind of an igneous rock
What is the rock of earths mantle?
plate tectonic and magma
What is the layer of the rock beneath the earths crust?
mantle
What is earths upper mantle composition?
hard rock
What layer of rock that is 67 of earths mass is?
Mantle
What will happen if the flow of hot rock in earths mantle if the planets core eventually cools?
The flow of hot rock in earths mantle will stop and Earth's magnetic field will disappear
Earths lower mantle lies just below the?
Earths lower mantle lies just below the upper mantle extending from 400 to 2,900 kilometers below the Earth's surface. This region primarily consists of dense, solid rock materials that experience high pressures and temperatures. The lower mantle plays a significant role in the Earth's mantle convection, which drives tectonic plate movements and heat transfer within the Earth.
What is the plastic like rock of the lower mantle called?
the plasic like rock of the lower mantle is the asthenosphere
What is the layer of rock that comprises 67 of earths mass?
The mantle.
