1. why do large jet airplanes fly in the stratosphere?
2. enumerate the factors affecting the distribution of insolation on the earth's surface?
3. the vertical rays of the sun give more heat than slanting rays. give reasons?
4. mention at least 2 differences between the troposphere, stratosphere and thermosphere.
Answers
Explanation:
Q1Ans :airplanes fly in the stratosphere is because this is where the least amount of turbulence is found
Q2Ans: Rotation of the earth on its axis. ...
The angle of incidence of the sun's rays. ...
Duration of the day. ...
Transparency of the atmosphere.
Q3Ans: Vertical rays are hotter than slanting rays due to the following reasons: Vertical rays heat up a smaller surface. Hence, the heat received per unit of area is large. ... Slanting rays travel a longer distance through the atmosphere where much of its heat is absorbed by clouds, water vapour, and dust particles.
Q4Ans: The troposphere is the lowest level of the atmosphere, so it is in contact with the Earth's surface.
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.
The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high
Answer:
1)The main reason airplanes fly in the stratosphere is because this is where the least amount of turbulence is found. In addition, because the stratosphere is very dry, there are fewer clouds in this layer, making for a much smoother ride overall.
2) The major factors which influence the amount of insolation received are: Rotation of the earth on its axis.

4) TROPOSPHERE;- it is the lowest layer of atmosphere, its height varies from 8km to poles 18 km from equator
Stratosphere;- it's the second layer above the earth, its height goes upto 50km.
THERMOSPHERE ;- layer of earths atmosphere,. .
