question no 22-
Answer -b. rising
Temprature in both the hemisphere is rising but in northern hemisphere more rapidly than southern hemisphere .
question no 23-
Answer- c. earth system
Global climate is a complex earth system that have many key components such that atmosphere , hydrosphere, lithosphere , biosphere ' cryosphere.
question no 24-
Answer- a. absorb energy that is reradiated fron the earth surface
Greenhouse gases are those which emits and absorb heat energy in thermal infrared range . This process of absorbtion and radiation of heat energy cause greenhouse effect . Some greenhouse gases are methane , carbondioxide ,water vapour ,nitrous oxide , ozone
Without these green house gases earth temprature would be about -15 degree celsius rather than 15 degree celsius
Question no 25-
Answer- b. Increases in albedo cause cooling
Albedo is define as the amount of sun radiation reflect back
Increase in albedo than it will be less absorbtion of sun heat energy
