Global water cycle consists of evaporation from water bodies (oceans, rivers, lakes etc.) and precipitation of water in the form of rain, snow and hail. Hence, water circulates between hydrosphere and atmosphere. It does not involve living organisms.

Read the given statements and select the correct option.Statement 1: G...
Statement 1: Global water cycle does not involve the living organisms.
The global water cycle, also known as the hydrological cycle, is the continuous movement of water on, above, and below the Earth's surface. It involves various processes such as evaporation, condensation, precipitation, and runoff. These processes occur naturally and do not require the direct involvement of living organisms. Therefore, statement 1 is correct.
Statement 2: In this cycle, water circulates between hydrosphere and atmosphere.
The global water cycle involves the movement of water between different reservoirs, including the hydrosphere (which includes oceans, lakes, rivers, and groundwater) and the atmosphere. Water evaporates from the hydrosphere and enters the atmosphere as water vapor. It then condenses to form clouds and eventually falls back to the Earth's surface as precipitation, which may replenish the hydrosphere. Therefore, statement 2 is also correct.
Explanation:
Both statements 1 and 2 are correct, and statement 2 is the correct explanation of statement 1. The global water cycle is a natural process that occurs on Earth and does not require the direct involvement of living organisms. It primarily involves the movement of water between the hydrosphere and the atmosphere through processes like evaporation and precipitation.
The water cycle starts when solar energy heats the Earth's surface, causing water to evaporate from oceans, lakes, and other bodies of water. Water vapor rises into the atmosphere and cools, condensing into clouds. Eventually, the water droplets in clouds combine and fall back to the Earth's surface as precipitation, which can take the form of rain, snow, sleet, or hail.
Once the water reaches the Earth's surface, it can follow various paths. It may flow over the land as runoff, replenishing rivers, lakes, and oceans. Some precipitation may infiltrate the soil and become groundwater, which can later be discharged into rivers or used by plants through transpiration. Additionally, plants and trees play a role in the water cycle by absorbing water through their roots and releasing it into the atmosphere through a process called transpiration.
Overall, the global water cycle is a continuous process that involves the circulation of water between the hydrosphere and the atmosphere. It is essential for maintaining the Earth's water balance and supporting various ecosystems and human activities.
