Troposphere is Denser. The lowest part of the troposphere is the warmest section of the layer, and it is denser than all its overlaying layers because a larger atmospheric weight sits on top of the troposphere and causes it to be severely compressed. 6.

The Moon has no moons. The Moon has no rings. More than 105 robotic spacecraft have been launched to explore the Moon.
The stratosphere is the second layer of Earth''s atmosphere, situated above the troposphere and below the mesosphere. It extends from about 10 to 50 kilometers above the Earth''s surface. This layer is characterized by the presence of the ozone layer, which plays a crucial role in absorbing the majority of the sun''s harmful ultraviolet radiation.
atmosphere, the gas and aerosol envelope that extends from the ocean, land, and ice -covered surface of a planet outward into space.

Beneath us, the very edge of the atmosphere — known as Earth''s "limb" — appears as a glowing halo of colors; a luminescent layer cake that gradually fades into the blackness of space. And suddenly our atmosphere, which seemed so vast and mysterious from the ground, appears shockingly thin, even fragile. So thought retired NASA ...
The Brief Overview. Earth''s atmosphere is a jacket of gases that surrounds our planet. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens.
When we talk about the Earth''s Atmosphere, what do we mean? Imagine a layer cake, wrapping around the Earth. That is essentially what the Earth''s …
mesosphere. noun. region in Earth''s atmosphere between the stratosphere and the thermosphere, about 50-80 kilometers (31-50 miles) above the Earth''s surface. meteor. noun. rocky debris from space that enters Earth''s atmosphere. Also called a shooting star or falling star. ozone layer. noun.
Earth is surrounded by a mixture of gases called the atmosphere. The composition of the atmosphere is 78 %. . nitrogen and 21 %. . oxygen, with the remaining 1 %. . consisting of water vapor, argon, carbon dioxide, and small amounts of other gases. Earth''s atmosphere consists of five distinct layers that are distinguished by ...
Earth''s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere. Earth''s troposphere extends from Earth''s surface to, on average, about 12 kilometers (7.5 miles) in height, with its height lower at …
The atmosphere is the body of gasses that surrounds our planet, held in place by earth''s gravity. Most of our atmosphere is located close to the earth''s surface where it is most dense. The air of our planet is 79% nitrogen and just under 21% oxygen; the small amount remaining is composed of argon, carbon dioxide, and other trace gasses. …
The atmosphere is the layer of gases around the Earth is held in place by Earth''s gravity is made up mainly of nitrogen (78.1%). It also has plentiful oxygen (20.9%) and small amounts of argon (0.9%), carbon dioxide (~ 0.035%), water vapor, and other gases.The atmosphere protects life on Earth by absorbing (taking) ultraviolet rays …
Learn about Earth''s atmosphere, its composition, layers, and functions. Find out how the atmosphere affects weather, climate, and life on Earth.

Earth''s atmosphere has changed through time. Compared to the Sun, whose composition is representative of the raw materials from which Earth and other planets in our solar system formed, Earth contains less of some volatile elements, such as nitrogen, argon, hydrogen, and helium. These elements were lost when the envelope of gases, or primary ...
Atmosphere. The atmospheric gases around Earth scatter blue light (shorter wavelengths) more than light toward the red end (longer wavelengths) of the visible spectrum; thus, a blue glow over the horizon is seen when observing Earth from outer space.
