Which of Earth’s layers is the coldest?
the mesosphere Located between about 50 and 80 kilometers (31 and 50 miles) above Earth's surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).

Which of the 5 layers of the atmosphere is the coldest and hottest?
Coldest layer of Earth's atmosphere is the MESOSPHERE. The temperature there is -90 degree celsius. It can even go lower. Hottest layer of Earth's atmosphere is the thermosphere.
What is hottest layer of the name?
The thermosphere The thermosphere is often considered the "hot layer" because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).
Is mantle the hottest layer of the Earth?
Answer and Explanation: The hottest layer of the Earth is its innermost layer, the inner core.

The outer core The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth's magnetic field. As Earth spins on its axis, the iron inside the liquid outer core moves around.
