What are the main features of stratosphere?​

Answer 1

Answer:

a) type of lapse rate

… air—commonly referred to as the normal, or environmental, lapse rate—is highly variable, being affected by radiation, convection, and condensation; it averages about 6.5 °C per kilometre (18.8 °F per mile) in the lower atmosphere (troposphere).

b) Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.

C) The troposphere is the lowest level of the atmosphere, so it is in contact with the Earth's surface. In contrast, the stratosphere is located above the troposphere, so it is not in contact with the Earth's surface. ... The air density and air pressure are much lower in the stratosphere.

d) the Earth's atmosphere protect and sustains the planets inhabitants by providing warmth and absorbing harmful solar rays. in addition to containing the oxygen and carbon dioxide which living things need to survive the atmosphere traps the sun energy and wards off many of the dangers of the space
