Answer: Troposphere
Explanation:
Different layers of atmosphere are:
Troposphere: It starts at the Earth’s surface and extends 8 to 14.5 km high. This part of the atmosphere is the most dense. Almost all weather is in this region,
Stratosphere: It starts just above the troposphere and extends to 50 km high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation is in this
layer,
Mesosphere: It starts just above the stratosphere and extends to 85 km high. Meteors burn up in this layer,
Thermosphere: It starts just above the mesosphere and extends to 600 km high. Aurora and satellites occur in this layer,
Ionosphere: It is an abundant layer of electrons and ionized atoms and molecules that
stretches from about 48 km above the surface to the edge of space at about 965 km, overlapping into the mesosphere and thermosphere. This dynamic region grows and shrinks based on solar conditions. The ionosphere is a critical link in the chain of Sun-Earth interactions. This region makes radio communications possible.
Exosphere: This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km.
