Question

5) Why does the earth appear flat to us?​

Answer 1

Answer:

The pressure within Earth's atmosphere is referred to as atmospheric pressure or barometric pressure (after the barometer).

Explanation:

The five distinct layers that make up the earth's atmosphere are identified by changes in temperature brought on by changes in height. Below is a discussion of these layers:

The exosphere is the top layer that faces space. It does not have a proper boundary that divides it from space. The air is so thin and disappears into space here.

The thermosphere, which is located under the exosphere, has a temperature range of 500 to 2000 °C. The absorption of UV and X rays from the sun is the cause of this high temperature. The air in this stratum is so thin that the temperature seems like frozen tundra. The earth's thermosphere is where the satellites are positioned. This layer allows the observation of auroral lights.

Mesosphere—The mesosphere extends 85 km from the surface of the planet and is located under the thermosphere. The temperature drops to around 90 °C, which is below the thermosphere. Between the troposphere and mesosphere lies a layer called the stratosphere. It reaches a distance of 40 km from the troposphere. The ozone layer, which is present in this layer, absorbs UV rays from sunlight and converts them into heat energy.

StratosphereThe troposphere is a stratum that extends upward for roughly 10 km. In the whole atmosphere, air makes up about 75% of the composition. In this region, 99.9% of water vapour is found. The temperature of this layer decreases as we ascend. As a result, as we go higher, clouds appear. The majority of greenhouse gases are concentrated in this layer, which traps heat close to the surface.
