troposzférában

The troposphere is the lowest layer of Earth's atmosphere, extending from the Earth's surface up to an average altitude of about 7 to 15 kilometers. This is the layer where all weather phenomena, such as rain, snow, clouds, and storms, occur. The temperature in the troposphere generally decreases with increasing altitude. This decrease is due to the fact that the troposphere is primarily heated from below by the Earth's surface, which absorbs solar radiation. As you move higher, the air becomes less dense and further from the heat source. The troposphere contains about 75% of the atmosphere's total mass and about 99% of its water vapor. The boundary between the troposphere and the layer above it, the stratosphere, is called the tropopause. The height of the tropopause varies depending on latitude and season, being higher at the equator and lower at the poles. The atmospheric pressure also decreases significantly with altitude within the troposphere.
