دورة الماء: رحلة قطرة الماء

Welcome to the first part of our water cycle journey! Today we'll explore evaporation and condensation.The water cycle begins with bodies of water like oceans, lakes, and rivers.The sun's rays heat the water's surface, providing energy for evaporation.As the water heats up, liquid water molecules gain energy and transform into water vapor, rising into the sky.As the water vapor rises, it encounters colder layers of the atmosphere.In these cold layers, the water vapor condenses, transforming back into tiny water droplets that form clouds.This process continues constantly, with water evaporating and condensing in a continuous cycle.These two processes - evaporation from the surface and condensation in the cold air - are fundamental to cloud formation.Now that we understand how water vapor rises and forms clouds, let's see what happens next in the water cycle.When water droplets in clouds become heavy enough, they fall as precipitation.Rain falls when water droplets become heavy enough.In cold conditions, precipitation falls as snow.Sometimes, precipitation falls as hail.The precipitation collects in bodies of water like lakes.Some water seeps into the ground, forming groundwater.Plants absorb some of this water and use it for transpiration.This continuous process of precipitation and collection is a crucial part of the water cycle.Water flows across the Earth's surface through rivers and streams, moving from high to low elevations.Rivers form as water flows from mountains down to the oceans.Water continuously flows through these channels, creating a network of rivers and streams that eventually reach the oceans.This continuous movement of water maintains the natural balance in Earth's water system.Let's review the key points about surface water flow and its return to the oceans.And so, the water cycle continues its endless journey, maintaining the balance of water in nature.
