Question

question number 7,9,10,11

Answer 1

7a. Atmosphere gets heated due to the phenomenon of greenhouse effect.

7b. Not sure how to articulate it.. But hot air goes up so let's say upward current.

9. Clouds r formed when water vapor goes up and gets cooled down at the troposphere and we see the clouds.. Clouds are actually very tiny water droplets.

Three human activities that cause air pollution are petroleum vehicles, thermal power plants, burning wood. All these release CO2, CO etc in the air leading to pollution. Deforestation also leads to pollution.


11. I will b short here. Let's do an analogy. Would you like to sit in a desert during summer day all day long. You would not right. Physically your body won't b able to cope with all the water loss in your body and you will suffer the result of dehydration. Now incase of aquatic organisms they have a range of temperature where their body functions optimally. If it heats up or cools down aggressively bodily functions cease to take place and leads to death.
