Students use water, ice, and plastic wrap to model the ocean and cold upper atmosphere. Students use observations from their model to explain the processes of evaporation and condensation that drive ...

Carbon, a building block of life, is constantly moving through different environmental compartments such as biota, the atmosphere, the ocean, soil and sediment, as part of what is called ‘the global ...

If the cup of cold water is not exposed to air, no condensation will form. The fast-moving molecules of water vapor transfer their energy to the side of the cup which is cooler. This causes the water ...

It follows a cycle of evaporation, condensation, precipitation and collection. The sun heats up water on land, in rivers, lakes and seas and turns it into water vapour. The water vapour rises into ...

The water cycle is the continuous journey of water from oceans and lakes, to clouds, to rain, to streams, to rivers and back into the ocean again. When the sun shines, it causes water to warm up ...
