Wind

Wind is moving air. It increases the rate of water loss from organisms therefore affecting their body. It carries water vapour to the upper parts of the atmosphere where it condenses and precipitates as rain. In desert areas wind aids in formation of sand dunes. Stable sand dunes may become habitats for growth of desert plants. Play the video to see a sand dune being formed.

Wind causes wave formation in lakes and oceans, which enhances aeration of water in these water bodies. In the video clip, sea storms are formed by strong waves of water blown by wind. Click on the play button to view the video clip.

Trees growing in areas experiencing strong winds may have stunted and distorted growth. Play the video to see strong wind blowing through the forest trees producing whistling sound. Wind also disperses spores and seeds and influence dispersal.
