WebApr 12, 2024 · In the Department of Earth, Planetary, and Space Sciences, we seek to understand the Earth and the planets. Our students, researchers, and faculty tackle a wide range of problems, from the Sun to the most distant planets, and from the center of the Earth to the tenuous ionized gases of the solar wind. ... We explore Earth's upper … WebIt gradually gives way to the vacuum of space. There is no precise top of the atmosphere, but the area between 100-120 km (62-75 miles) above the Earth's surface is often considered the boundary between the atmosphere and space because the air is so thin here.

What is the Atmosphere? Center for Science Education
In general, air pressure and density decrease with altitude in the atmosphere. However, the temperature has a more complicated profile with altitude, and may remain relatively constant or even increase with altitude in some regions (see the temperature section, below). Because the general pattern of the temperature/altitude profile, or lapse rate, is constant and measurable by mean… WebNov 7, 2024 · The mesosphere extends from the stratopause (the upper boundary of the stratosphere) to about 85 kilometers (53 miles) above the surface of the Earth. Here, … Upper atmosphere is a collective term that refers to various layers of the atmosphere of the Earth above the troposphere and corresponding regions of the atmospheres of other planets, and includes: • The mesosphere, which on Earth lies between the altitudes of about 50 and 80 kilometres (31 and 50 mi), sometimes considered part of the "middle atmosphere" rather than the upper atmosphere green corset gown
