Detailed explanation-1: -Due to solar radiation, water evaporates, generally from the sea, lakes, etc. Water also evaporates from plant leaves through the mechanism of transpiration. As the steam rises in the atmosphere, it is being cooled, condensed, and returned to the land and the sea as precipitation.

Detailed explanation-2: -Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents.

Detailed explanation-3: -Carbon dioxide (CO2): Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions (e.g., manufacture of cement).

Detailed explanation-4: -The consequences of climate change now include, among others, intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity.

Detailed explanation-5: -In the water cycle, evaporation transports water from the Earth into the atmosphere, and precipitation transports water back to the Earth.
