The mantle
The lower layer of the mantle, known as the mesosphere, is primarily composed of solid silicate minerals rich in magnesium and iron, such as olivine and pyroxene. This region experiences high pressure and temperature, which keeps the materials solid despite their proximity to the molten outer core. The lower mantle plays a crucial role in Earth's geology, affecting mantle convection and plate tectonics.

The lower mantle remains solid due to high pressure, which increases the melting point of minerals. The pressure at such depths is so immense that it keeps the minerals stable in a solid state despite the high temperatures.
The high pressure in the lower mantle keeps rocks solid even if they exceed their melting point, as pressure can suppress melting. Additionally, the presence of minerals with high melting points, such as silicates, contributes to the rocks remaining solid below their melting point. The slow rate of heat transfer in the solid rock also plays a role in preventing it from reaching its melting point.
The mantle is kept from cooling down and solidifying due to the heat generated from the decay of radioactive elements in the Earth's core. This heat creates convection currents within the mantle, which continuously bring warmer material from deeper layers up towards the surface, helping to maintain the mantle's high temperature and molten state.

Evaporative cooling triangle hat keeps your head cool.
The AC compressor turns off while the fan keeps running to circulate air and maintain ventilation in the room. This helps prevent the room from becoming stuffy or stagnant, even when the cooling function is not actively running.
yes but i found out if you tap into the wires on the cooling fan it keeps you running cooler and keeps your car running smooth
keeps them strong, and prevents them from becoming brittle
Gravity keeps you on the earth.....
