Which of these causes the lower mantle to remain solid despite high temperatures?

What is a layer of the Earth that contains partially molten rock and very high temperatures?
The asthenosphere, part of the upper mantle.
WHY IS THAT THE EARTHS INTERIOR IS BELIEVED TO HAVE HIGH TEMPERATURES?
The interior core contains many nuclear properties which gives of huge amounts of heat which then heats the core.
Why do rocks have to be in the mantle to change to a metamorphic rock?
The short answer is that they don't! For metamorphism to occur rocks require either heat, pressure or a combination of the two. Both of these conditions occur together in the mantle, however they can occur in other places to. Such as in the rocks around igneous intrusions (high temperatures and low to moderate pressures) which cause contact metamorphism. It can also occur in zones of high tectonic stress (such as continental collision zones where mountains are being built where there is a relatively low temperature by mantle standards but very high pressure) which causes regional metamorphism. Finally in zones characterised by very high strains (e.g. the rocks in very close proximity to fault zones) metamorphism can occur. The type depends on the strain rate and the depth (which affects the pressure and temperature). This type of metamorphism is known as dynamic metamorphism). All the above conditions (and a number of others) can cause metamorphism to occur in sections of the earth outside the mantle. The differing types of metamorphism at differing temperatures and pressures create differing assemblages of minerals. These are known as metamorphic facies.

Why can diamonds form in the mantle?
The weight of the rocks above the mantle results in high pressure.Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.

How is it possible for mantle rock to flow?
Mantle rock is composed of a type of igneous rock peridotite which has a high iron and magnesium content. This rock is so hard and dense that it is not able to flow like a liquid. However due to the high temperatures and pressures that are present in the mantle it is possible for mantle rock to flow like a plastic-like material. This process is called "plastic deformation". Plastic deformation occurs when temperatures and pressures are high enough to cause the atoms in the rock to rearrange themselves. This rearrangement allows the rock to become more malleable and it is able to bend and flow like a liquid. This process is responsible for many of the changes that occur in the mantle such as convection currents and plate tectonics. The process of plastic deformation is not easily observed as it occurs deep within the Earth. However scientists have been able to determine the amount of pressure and temperature necessary to cause plastic deformation in mantle rock. It is estimated that temperatures must be at least 2000 degrees Celsius and pressures must be at least 10000 times the atmospheric pressure at sea level in order for mantle rock to flow. In summary mantle rock is composed of peridotite a type of igneous rock that is so hard and dense that it is not able to flow like a liquid. However due to the high temperatures and pressures that are present in the mantle it is possible for mantle rock to flow like a plastic-like material through a process called "plastic deformation". This process is responsible for many of the changes that occur in the mantle such as convection currents and plate tectonics. Temperatures must be at least 2000 degrees Celsius and pressures must be at least 10000 times the atmospheric pressure at sea level in order for mantle rock to flow.
