The thermosphere is the atmospheric layer located between the mesosphere and exosphere. It is known for its high temperatures and is where the auroras occur due to interactions with solar radiation.
the layers of the atmosphere in order are troposphere, stratosphere, mesosphere, thermosphere, and exosphere
The atmospheric layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has distinct characteristics, such as temperature variations and composition, and plays a specific role in regulating Earth's climate and protecting life on the planet.
The uppermost layer of the atmosphere is the exosphere. It extends from about 500 km above the Earth's surface and gradually transitions into outer space. The exosphere is where atmospheric particles are so sparse that they can travel long distances without colliding with one another.
Mesosphere
The coldest layer of the atmosphere is the mesosphere, which starts around 31 miles (50 kilometers) above the Earth's surface and extends up to about 53 miles (85 kilometers). Temperatures in the mesosphere can drop as low as minus 130 degrees Fahrenheit (minus 90 degrees Celsius).
