How does Earth's atmosphere help it to sustain life? An Important Layer Of Gases: The earth's atmosphere consists of five layers of gases that surround it and are held in by the force of gravity. Each layer has significant differences in its composition and general function. The earth's ...
So that’s what created the water M: It’s not the collision that created water. Comets contain water. They’re made up mostly of cosmic dust and water. When they collide with the atmosphere, they break up. And the water they contain rains down to earth. Ocean water came from that ...

Mostly, the Earth's atmosphere blocks out photons with a shorter wavelength than ultraviolet light. This makes it difficult to study the Sun's inner workings from Earth directly. However, we do have our ways.Many ground-based telescopesuse a grid of sensors also known as a charge-coupled dev...
How does the atmosphere protect life on earth? Earth's Atmosphere: The atmosphere is a blend of gases covering the Earth. It consists of roughly {eq}78\% {/eq} of nitrogen, {eq}21\% {/eq} of oxygen, and {eq}1\% {/eq} of other gases, such as {eq}{\rm{C}}{{\rm{O}}_...
Geographers broadly divide the different areas of our planet into spheres. The atmosphere is the term most commonly used, referring to all air around our planet, while the hydrosphere refers to all water in oceans and lakes, and the geosphere refers to the hard rocks of the Earth...
Research indicates that the U.S. oil and gas industry emits 16.9 million metric tons of methane every year, according to the International Energy Agency.3Some of this methane is inadvertently leaked through faulty equipment or deliberately vented into the atmosphere between extractions. The Environmen...
