The Mesosphere.
The mesosphere is the coldest layer of the earth's atmosphere.
The mesosphere is the layer of the atmosphere that exists between the stratosphere and the thermosphere. It contains the coldest parts of the Earth's atmosphere, reaching temperature depths of -90°C.
No, the ionosphere is not the coldest layer of Earth's atmosphere. The coldest layer is actually the mesosphere, which is located above the stratosphere and below the thermosphere. Temperatures in the mesosphere can drop as low as -90 degrees Celsius.
The crust is the coldest layer of the Earth because it is the closest to the surface, where it interacts with the atmosphere. The heat from the Earth's interior is trapped beneath the crust, resulting in cooler temperatures at the surface.
mesosphere
The coldest layer of the atmosphere is the mesosphere, which extends upwards from about 31 miles to 53 miles above the Earth's surface. Temperatures in the mesosphere can drop as low as -130 degrees Fahrenheit (-90 degrees Celsius).
The coldest region in the Earth's atmosphere is found in the mesosphere, which is the third layer from the Earth's surface. Temperatures in the mesosphere can drop as low as -90 degrees Celsius (-130 degrees Fahrenheit).
From Wikipedia:Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around −100 °C (−148.0 °F; 173.1 K)the mesosphere is the coldest layer in the atmosphere. It contains the ozone.OK!! the answer above is incorrect the coldest layer in the atmosphere is the Mesopause its the thin layer between the Mesosphere and Thermosphere. Also the Ozone is in the Stratosphere.Actually its correct because the mesopause is a part of the mesosphere....ok the 1st and 3rd answers are wrong! i should know im learning this in my 7TH GRADE SCIENCE CLASS! the ozone is in the stratosphere, the second closest layer to the earth. STUPIDS!
thermosphere
thermosphere
The coldest layer of the atmosphere is the mesosphere, which sits above the stratosphere and below the thermosphere. Temperatures in the mesosphere can drop as low as -90 degrees Celsius (-130 degrees Fahrenheit), making it extremely cold.
