Air, Water & Weather Worksheets For Grade 4
Air, water & weather worksheets for grade 4 students cover different topics related to air, air pollution, water and water pollution. It also delves into weather related topics. Five worksheets on each sub-topic are given here to help class 4 students learn these topics well.
Air
Sea breeze and land breeze are distinct phenomena influenced by differential heating and cooling of land and water. During the day, as land heats up faster than water, warmer air rises over the land, creating a low-pressure area. Cooler air from the sea flows inland to replace it, generating a refreshing sea breeze. Conversely, at night, land cools faster, creating a high-pressure zone. Cooler air descends, and warmer air from the sea moves towards land, resulting in a land breeze.
Water
The water cycle is a continuous process where water evaporates from oceans, lakes, and rivers due to heat, condenses into clouds, and precipitates as rain or snow. Condensation occurs when water vapor cools and forms droplets. Evaporation happens when liquid water turns into vapor. Water purification ensures safe drinking water by removing contaminants. Saving water through efficient use and conservation practices helps sustain ecosystems.
Weather
Weather refers to the day-to-day atmospheric conditions in a specific place, it is changed with time due to factors like temperature, humidity, precipitation, and wind. Seasons are caused by the tilt of the Earth's axis relative to its orbit around the Sun. This tilt causes varying amounts of sunlight to reach different parts of the Earth during its year-long orbit, leading to the cycle of seasons—spring, summer, autumn, and winter—as different hemispheres experience either longer or shorter days and varying sunlight angles.
