Question

How many miles up in the Earth’s atmosphere.?

Answer 1

Hint: Atmosphere refers to the gases encompassing a star or planetary body held set up by gravity. The arrangement of the Earth's air is around 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, water vapor, carbon dioxide, and different gases.

Complete answer: The atmosphere develops more slender (less thick and lower in weight) as one moves upward from the surface of the Earth. The atmosphere bit by bit offers a route to the vacuum of space. There is no exact "top" of the atmosphere. The air turns out to be so thin at elevations somewhere in the range of 100 and 120 km (62-75 miles) up that for some reason that scope of statues can be viewed as the limit between the climate and space. In any case, there are exceptionally slender yet quantifiable hints of climatic gases many kilometers/miles over our planet, Earth's surface.
There are a few unique layers in the atmosphere. Each has trademark temperatures, weights, and phenomena. We live in the lower atmosphere, the lowest layer, where most mists are found and practically all weather occurs. Some jet airplanes fly in the following higher layer, the stratosphere, which contains the jet streams and the ozone layer. Higher layers are the mesosphere, thermosphere and exosphere.
Earth's atmosphere is around 300 miles thick, yet the vast majority of it is inside 10 miles the surface. Pneumatic force diminishes with height. At Sea level, pneumatic stress is about 14.7 pounds per square inch (1 kilogram for each square centimeter). At 10,000 feet, the gaseous tension is 10 pounds for every square inch (0.7 kg per square cm). There is additionally less oxygen present to breathe.

Note: Earth is the lone planet in the close planetary system with a climate that can support life. The cover of air contains the gases that we inhale as well as the gases which shield us from the impacts of warmth and radiation exuding from the sun. It warms the planet by day and cools it around the time of evening.
