Answer 1

water cycle and melting of glaciers or photosynthesis

Answer 2

Explanation:

Three changes that occur only in the presence of sunlight are as follows.

• Water cycle
• Charging of solar cells
• Photosynthesis

In the process of water cycle, water from the clouds fall on mountains, glaciers etc. Further, it flows and mixes into rivers, ponds, lakes and eventually it reaches to oceans. When sunlight falls on this water, it starts to evaporate into the atmosphere and finally reaches to the sky again. Hence, this cycle continues.

Charging of solar cell is a process in which solar cells are placed in sunlight to get charged so that these can be used to cook food, generate electricity etc.

Photosynthesis is a process in which plants prepare their own food in the presence of sunlight.
