Located under the mantle the outer core can reach temperatures of up to 8,500 degrees Farenheight. Unlike the Lithosphere, it is only semi-rigid (displays more fluidity) and is contrived of dense hot rock (much hotter than lithosphere) that flows under the heavyweight of the lithosphere.
Temperature Range:
On average, the surface of the Earth’s crust experiences temperatures of about 14°C. However, the hottest temperature ever recorded was 70.7°C (159°F), which was taken in the Lut Desert of Iran as part of a global temperature survey conducted by scientists at NASA’s Earth Observatory.
The Earth’s layers from coolest to hottest are: crust, mantle, outer core, and inner core.
The interior of Earth is very hot (the temperature of the core reaches more than 5,000 degrees Celsius) for two main reasons: The heat from when the planet formed, The heat from the decay of radioactive elements.
The hottest rock near the bottom of the mantle becomes slightly less dense than the somewhat cooler rock above it, so buoyancy forces try to push the hottest rocks upward. Although the rock in the mantle is solid, the pressures and heat are so great that the rock can deform slowly, like hot wax.
The Earth’s layers from coolest to hottest are: crust, mantle, outer core, and inner core.
The lowest part of Earth’s atmosphere is called the mesosphere and it has a temperature of minus 130 degrees F.
The mesosphere
The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth’s atmosphere, about -90° C (-130° F), are found near the top of this layer.
So the mantle is so hot that in some regards, it acts like a fluid. This is important because according to our understanding, there are convection currents in the mantle that move the tectonic plates around (and contribute to numerous geological processes). … Simplistic depiction of convection currents.
Earth’s mantle has the huge volume than any layer of the Earth. The lower mantle is composed of solid materials and has very high temperature. … Hence the mantle up-welling (convection) and mantle down-welling could cause some parts of the lower mantle hotter than the other parts.
The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.
The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.
