Write four characteristics features of the two layers of atmosphere closest to the Earth
Answers
troposphere
stratosphere—contains the ozone layer; the layer where volcanic gases can affect the climate. tropopause—the boundary between the stratosphere and troposphere. troposphere—the layer closest to Earth's surface in which all weather occurs.
Answer:
TROPOSPHERE - This layer of the atmosphere is the densest - about 80% of the total mass of the atmosphere lies here. The troposphere is responsible for the weather on Earth. The height of the top of the troposphere varies with latitude - it is lowest over the poles and highest at the equator - and also by season - it is lower in winter and higher in summer. It can be as high as 20 km near the equator, and as low as 7 km over the poles in winter.
The STRATOSPHERE starts where the troposphere ends, and extends to 50 kilometers up. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. The stratosphere is very dry; the air contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere. Jet aircraft reach their maximum operational altitudes within the stratosphere because the air is a lot thinner than at lower levels - resulting in fuel economy and less turbulence.
