Describe the journey that a water molecule takes in the water cycle from an atom in precipitation to an atom inside a cloud.

Step 1: Precipitation:

At the right conditions of preesure and teperature, large droplets of water are formed from the small ones in clouds and rain falls. This process is called precipitation.

Step 2: Runoff:

The rainfall usually strams down the earth and flows down lakes, rovers and oceans. This process is called runoff.

Step 3: Infiltration:

This process occurs when the rain water goes below the surface of the earth into the soil and the rocks that are beneath the surface.

Step 4: Transpiration:

The water that went through the soil is absorbed by the roots of the plants. It makes its way through the stem until it reaches the leaves where it evaporates and adds to the already existing water vapor in the air. This process of evaporation is called transpiration.

Step 5: Evaporation:

This process occurs when water changes from the liquid state to the gaseous state.

Step 6:Condensation:

This process occurs when the water chanfes from the gaseous state into the liquid state.

Step 7: Precipitation again...and the cycle repeats

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
