However, the temperature stabilizes at 7.5 miles (12 kilometer) above the surface of the Earth. The ionosphere is a layer of charged particles (ions) that stretches from 48 km above the surface to around 965 km. This website uses cookies to improve your experience while you navigate through the website. Atmosphere Our planet earth is enveloped by a deep blanket of gases extending several thousands of kilometres above its surface. From the surface of the Earth, it extends out to about 3.7-5 miles (6-8 kilometers), at the poles and 10.5 miles (17 kilometers) at the equator. This layer has a composition of less dense helium, hydrogen, and molecules of nitrogen, oxygen and carbon dioxide. The layer has no clouds and no water vapor. The ionosphere stretches from 49.7 miles to 341 miles (80 to 550 kilometers), above the Earths surface. Atmospheric science is the study of the atmosphere. Constant mixing of the contents of atmosphere occurs due to air currents and the vertical temperature gradient. The life on the Earth exists because of the atmosphere that surrounds it. Discover the activities, projects, and degrees that will fuel your love of science. It is hard to define where the exosphere ends and the outer space starts. Thermopause lies between 155 to 310 miles (250 to 500 kilometers) above the earth surface. The stratosphere is very important for the preservation of animal life on the Earth. Ozone reacts with the ultraviolet rays and gives out heat, which warms the upper layers of the stratosphere. Atmosphere is, therefore, a quick and effective media for transfer, transport and dissemination of gaseous wastes. The stratopause acts as the boundary between the stratosphere and the mesosphere. The mesosphere extends from just above the stratosphere to 53 miles (85 km) high. Ans.

Ionosphere: The ionosphere contains electrically charged molecules of the oxygen, nitrogen and other elements which reflects the radio waves back to the Earth and enables the long distance communication.

Different atmosphere layers have different characteristics and roles. On top of the stratosphere is the mesosphere which is the third layer of atmosphere from the surface of the earth. Its size varies with daytime and nighttime. Most important part of the troposphere is the biosphere which extends from the surface to the maximum altitude that birds can attain. The troposphere is the innermost and the lowest layer of the atmosphere from the earth’s surface. Lies just above the troposphere, extending up to 31 miles (50 km) high. The planet Earth was formed about 4.5 billion years ago, after the collapse of the supermassive gaseous body. It is calculated that exosphere sides (lower limit) with the thermosphere at around 310 to 620 mile (500 to 1,000 kilometers) above the Earth’s surface. However, the tremendous increase in the industrial activity is taking its toll on the atmosphere. this is where Earth’s jet stream (a narrow, fast, winding air current) is found as well. Of all the atmospheric layers, this is the most closest to the Earth. Our site includes quite a bit of content, so if you're having an issue finding what you're looking for, go on ahead and use that search feature there! Ans. This Buzzle article lists some more information related to the…. 4. Well, we're looking for good writers who want to spread the word. The names of these layers, in order of lowest to highest, are: Temperature: 62°F (17°C) around the lowest point  to -60°F (-51°C) near the top. It separates the layers, mesosphere and the thermosphere. Above the thermopause is the uppermost layer of the atmosphere known as the exosphere. How Much Of The Amazon Rainforest Is Left. Article was last reviewed on Wednesday, July 15, 2020, Your email address will not be published. It extends to a height of about 12 km from the surface of the earth. Sun blasts the Earth with the energy or heat in the form of infra-red radiations which atmospheric gases retains and reflects to the Earth. The atmosphere is an integral life supporter on earth as it absorbs ultraviolet solar radiation, causes the greenhouse effect, and also adjusts the temperature to suit day and night levels. 5. Temperatures in the mesosphere can be as low as -148º F (-100º C). We hope you are enjoying ScienceStruck! As time moved on, the Earth cooled down and is still cooling, as of today.
