Lowest layer of atmosphere is

The five main layers of the Earths atmosphere. (Image credit: Future) The layers are separated based on temperature according to the National Institute of Water and Atmospheric Research (NIWA).The atmosphere thins out in each higher layer until the gases dissipate in space. Air pressure decreases with altitude. At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter), and the atmosphere is relatively dense. At 10,000 feet (3 km), the air pressure is 10 pounds per square inch (0.7 kg per square cm), which means molecules of gas that make up the atmosphere are less dense. That makes it harder for a person to breathe and get enough oxygen to live, although there is evidence for microbial life Troposphere The troposphere is the lowest and densest layer of the atmosphere and according to NIWA, approximately 75% of all the air in the atmosphere is found in this layer. The troposphere extends from Earth's surface to approximately 5 to 9 miles (8 to 14.5 km) high. According to NASA, the height of the troposphere is According to NASA, "Tropos" Stratosphere The stratosphere is the second layer of Earth's atmosphere. The stratosphere begins above the troposphere and extends approximately 31 miles (50 km) high. According to NIWA, most of the ozone found in Earth's atmosphere is in the stratosphere. Ozone protects us by absorbing harmful UV rays from the sun. The absorption of UV radiation heats up the stratosphere and temperatures in this laye...

"This is an unambiguous sign of changing atmospheric structure," study co-author Bill Randel, a scientist at the National Center for Atmospheric Research in Boulder, Colorado, said in a statement. "These results provide independent confirmation, in addition to all the other evidence of climate change, that greenhouse gases are altering our atmosphere."

It extends from sea level to a height ranging from 4.3 miles (7 kilometers) above the poles to 12.4 miles (20 km) over the tropics. As the layer of atmosphere that contains the most heat and moisture, it's also where a lot of atmospheric weather occurs. Air in the atmosphere expands when it's hot and contracts when it's cold, so the troposphere's upper boundary, called the tropopause, naturally shrinks and expands with the changing of the seasons. But by analyzing atmospheric data such as pressure, temperature and humidity — taken between 20 and 80 degrees no...

Atmosphere An atmosphere contains the air that we breathe and is a blanket of gases that surrounds Earth. It is held near the surface of the planet by Earth’s gravitational attraction. A barometer is used to measure air pressure. Argon, oxygen and nitrogen from the three main constitutions of the atmosphere. In this article, let us know in detail about the atmosphere. Table of Contents • • • • • What Is Atmosphere? An atmosphere is a blanket of gases that surrounds Earth. It is held near the surface of the planet by Earth’s gravitational attraction. Argon, oxygen and nitrogen from the three main constituents of the atmosphere. Definition “Atmosphere is a protective layer of gases that shelters all life on Earth, keeping temperatures within a relatively small range and blocking out harmful rays of sunlight.” Features of the Atmosphere: • Helps retain the sun’s heat and prevents it from escaping back into space. • Protects life from harmful radiation from the sun. • Plays a major role in Earth’s water cycle. • Helps keep the climate on Earth moderate. There is no boundary between the atmosphere and outer space. The atmosphere gets less dense and denser until it “blends” into outer space. Layers of Atmosphere What do you see when you stand outside and look up? A blue sky? A group of clouds? At night you might see a crescent moon, stars, a satellite. What you are not seeing, however, is the complexity of our atmosphere. The atmosphere has five distinct layers t...

The troposphere (seen here in orange) is the lowest layer of Earth’s atmosphere and where nearly all weather occurs. Over the last 40 years, the boundary between the troposphere and the neighboring stratosphere (pink) has risen as a result of climate change. Image Science & Analysis Laboratory/NASA Johnson Space Center Global temperatures are rising and so, it seems, is part of the sky. Atmosphere readings collected by weather balloons in the Northern Hemisphere over the last 40 years reveal that Science Advances. Temperature is the driving force behind this change, says Jane Liu, an environmental scientist at the University of Toronto. The troposphere varies in height around the world, reaching as high as 20 kilometers in the tropics and as low as seven kilometers near the poles. During the year, the upper boundary of the troposphere — called the tropopause — naturally rises and falls with the seasons as air expands in the heat and contracts in the cold. But SN: 10/26/21). Liu and her colleagues found that the tropopause rose an average of about 200 meters in height from 1980 to 2020. Nearly all weather occurs in the troposphere, but it’s unlikely that this shift will have on a big effect on weather, the researchers say. Still, this research is an important reminder of the impact of climate change on our world, Liu says. “We see signs of global warming around us, in retreating glaciers and rising sea levels,” she says. “Now, we see it in the height of the troposphere.” Qu...
