DAY : 4🔗

Topic: Clouds, rain and snow, water falls

Vocabulary: Condensed, water vapor, precipitation, atmosphere, droplets, freezing, stream

Material required: picture and books

Presentation: • Water forms are of different types as clouds, rain, snow, waterfalls, oceans, rivers, glaciers and lakes • Clouds are visible mass of condensed water vapor. They are suspended in the atmosphere above the ground or higher layers of the atmosphere. • Rain and snow are the most common forms of precipitation • Rain is formed by the process of evaporation and condensation. Water from the rivers, lakes and oceans evaporates and condense to form liquid droplets which form clouds. As these droplets become heavy, they fall onto Earth in the form of rain • Snow is formed when the water vapor in the clouds turn into tiny ice crystals. It is formed in the atmosphere at temperatures below freezing point • Waterfalls are most common in mountainous rocks. It is a sleep fall of a river or stream. They are usually formed when a river flows over a hard rock overlying a soft one.
