mesosphere.
thermosphere
The coldest point in the atmosphere is known as the tropopause. This boundary separates the troposphere and the stratosphere, and temperatures can drop significantly as you move higher into the stratosphere.
The coldest part of Jupiter is its upper atmosphere, which can reach temperatures as low as -145°C (-234°F). This frigid temperature is due to the distance from the Sun and the lack of a solid surface on the planet to retain heat.
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!
Neptune is the coldest planet but not by much. Neptunes surface temperature is 72K whereas Uranus is 76K.
Mesosphere
The coldest region of Earth's atmosphere is the mesosphere, which is located between the stratosphere and the thermosphere. Temperatures in the mesosphere can drop as low as -90 degrees Celsius (-130 degrees Fahrenheit).
The Antarctic zone has the coldest winters.
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).
The polar climate zone is the coldest due to its location near the poles, where sunlight is limited and temperatures remain low throughout the year. Additionally, the snow and ice cover in this region reflect sunlight, preventing the ground from warming up. These factors combine to create the coldest climate zone on Earth.
Coolest or coldest?? The coldest region is definitely the Antarctic. Antarctica to be exact.
The mesosphere is the coldest layer of the earth's atmosphere.
thermosphere
Greenland
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.
