👉 The Mesosphere is a part of Earth's atmosphere that is composed primarily of nitrogen and oxygen, with trace amounts of water vapor. It acts as a shield to protect the Earth from the sun's ultraviolet radiation, and it also plays a crucial role in regulating atmospheric pressure and temperature by trapping heat. Mesospheric regions are characterized by their high temperatures and low pressure. They are located at altitudes between 20,000 and 30,000 feet (6
