The mesosphere (/ ˈmɛsəsfɪər, ˈmɛz -, ˈmiːsə -, - zə -/; [1] from Ancient Greek μέσος (mésos) 'middle' and - sphere) is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, …

The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet.

Mesosphere, region of the upper atmosphere between about 50 and 80 km (30 and 50 miles) above the surface of the Earth. The base of the mesosphere is defined as the temperature maximum existing at the top of the stratosphere, with the boundary between the two regions usually called the stratopause.

2025年4月7日 · What is the mesosphere? The mesosphere is a layer of Earth’s atmosphere. The mesosphere is located above the stratosphere and below the thermosphere. The mesosphere lies between the thermosphere and the stratosphere.

2024年8月20日 · The gases in the mesosphere are now thick enough to slow down meteors hurtling into the atmosphere, where they burn up, leaving fiery trails in the night sky. Both the stratosphere (next layer down) and the mesosphere are considered the middle atmosphere.

2023年10月6日 · The mesosphere extends from just above the stratosphere to 53-62 miles (85-100 km) high. It is the coldest layer of the atmosphere, with the temperature dropping to its lowest at the boundary between the mesosphere and thermosphere, called the mesopause.

Earth's atmosphere is composed of a series of layers, each with its own specific traits. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The exosphere gradually fades away into the realm of interplanetary space.

The mesosphere is the atmosphere layer located above the stratosphere and below the thermosphere. It is an extremely cold layer at short distances. It is the place where shooting stars can be observed and where spacecraft observe the different structures of the winds.

The mesosphere is a layer of the Earth's atmosphere that extends from about 50 to 85 kilometers (31 to 53 miles) above the Earth's surface. The mesosphere consists mainly of oxygen, nitrogen, and small amounts of other gasses such as carbon dioxide and helium.

2014年9月7日 · The mesosphere is the third layer of Earth’s atmosphere, located above the stratosphere and below the thermosphere, at altitudes of about 50 to 85 kilometers (31 to 53 miles).
