What is O3 oxygen?
What is O3 oxygen?
Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth’s upper atmosphere.
What does the troposphere do?
The water cycle also occurs in this layer of the atmosphere. The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather.
What are 3 characteristics of exosphere?
The exosphere is largely composed of light gases such as hydrogen, carbon dioxide, atomic oxygen, and helium. All of the gases described above are so light that they can escape the Earth’s gravitational magnetic force and scatter freely across space.
Is the exosphere the coldest layer?
exosphere—contains few particles that move into and from space. mesopause—the boundary between the mesosphere and the thermosphere; the coldest place on Earth. mesosphere—the layer in which most meteors burn up after entering Earth’s atmosphere and before reaching Earth’s surface.
What is the meaning of exosphere?
In the case of bodies with substantial atmospheres, such as Earth’s atmosphere, the exosphere is the uppermost layer, where the atmosphere thins out and merges with outer space. The Earth’s exosphere is mostly hydrogen and helium, with some heavier atoms and molecules near the base.
What happens in the exosphere layer?
Most gas particles in the exosphere zoom along curved paths without ever hitting another atom or molecule, eventually arcing back down into the lower atmosphere due to the pull of gravity. However, some of the faster-moving particles don’t return to Earth – they fly off into space instead!
What can be found in exosphere?
The exosphere layer is mainly composed of extremely low densities of hydrogen, helium and several heavier molecules including nitrogen, oxygen and carbon dioxide closer to the exobase. The atoms and molecules are so far apart that they can travel hundreds of kilometers without colliding with one another.
