Atmosphere: Earth, The Power of the Planet. In this landmark BBC series, Dr Iain Stewart tells the story of how our planet works and how, over the course of 4.6 billion years, it came to be the remarkable planet it is today.
Examining the great forces that shape the earth – volcanoes, the ocean, the atmosphere and ice – the programme explores their central roles in our planet’s story. How do these forces affect the earth’s landscape, its climate, and its history? CGI gives the audience a ringside seat at these great events, while the final episode brings together all the themes of the series and argues that earth is an exceptionally rare kind of planet – giving us a special responsibility to look after our unique world. This is a series that shows the earth in new and surprising ways. Extensive use of satellite imagery reveals new views of our planet, while time-lapse filmed over many months brings the planet to life. Layers of the Atmosphere Documentary by Mrs. Weber's Class. Earth’s Atmosphere Top to Bottom. The air you breathe is precious, and the farther from Earth's surface you go, the less there is.
But Earth's atmosphere extends farther into space than you might realize, affecting the orbits of spacecraft more than 200 miles high. OurAmazingPlanet looks at what's in the atmosphere, from way out there, to up where the clouds hang out, to right down here [See Also: Earth from the Tallest Mountain to the Deepest Ocean Trench].

Atmosphere - animated diagram. Earth - Reveal Earth's Atmosphere. Layers of The Atmosphere. The Layers of Our Atmosphere In order to better understand our atmosphere, scientists have divided it into several layers.
These layers are divided based on the characteristics of the gases found at that height. Imagine a layered cake. A layered cake is made out of layers of different ingredients. The first layer might be cake mix. The first layer of the atmosphere is, fortunately, not made out of cake, but rather it is made out of the gases that we breathe everyday. Earth's Atmosphere. Layers of the Atmosphere. Scientists divided the atmosphere into four layers according to temperature: troposphere, stratosphere, mesosphere, and thermosphere.
The temperature drops as we go up through the troposphere, but it rises as we move through the next layer, the stratosphere. The farther away from earth, the thinner the atmosphere gets. TROPOSPHEREThis is the layer of the atmosphere closest to the Earth's surface, extending up to about 10-15 km above the Earth's surface. It contains 75% of the atmosphere's mass. The troposphere is wider at the equator than at the poles. This layer lies directly above the troposphere and is about 35 km deep. Earth's Atmosphere - Zoom Astronomy. The Earth's atmosphere is a thin layer of gases that surrounds the Earth.
It composed of 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide, and trace amounts of other gases. This thin gaseous layer insulates the Earth from extreme temperatures; it keeps heat inside the atmosphere and it also blocks the Earth from much of the Sun's incoming ultraviolet radiation. The Earth's atmosphere is about 300 miles (480 km) thick, but most of the atmosphere (about 80%) is within 10 miles (16 km) of the surface of the Earth.
There is no exact place where the atmosphere ends; it just gets thinner and thinner, until it merges with outer space. Air Pressure: At sea level, the air pressure is about 14.7 pounds per square inch.
