The carbon cycle has played a critical role in the history of our planet. Found everywhere on earth, in the oceans and the atmosphere, carbon is also crucial to the life of animals, plants and bacteria. This motion-graphics based clip outlines the carbon cycle. It explains how carbon is removed from the atmosphere, transferred from one organism to another, and returned to the atmosphere. Show Less

The continuously moving nitrogen cycle is essential to life on earth. Found in the cells of all living things, it is also the most common gas in our atmosphere. This motion-graphics based clip looks at how nitrogen is removed from the atmosphere, changed into a form that plants can absorb, is passed up the food chain, and returned to the atmosphere.

Phosphorus is an essential nutrient for all plant and animal life inhabiting the earth, including marine and fresh water environments. The key steps of the phosphorus cycle: weathering and erosion of phosphorus rich rock; how phosphates move into and up the food chain; and through sedimentation, turn back into solid form, are explained in this motion-graphics based clip.

Water is one of our planet's most important substances. It sustains all living organisms and enables many crucial biological, chemical and physical processes to occur. This motion-graphics based clip explains the processes involved in the water cycle including: evaporation, transpiration and sublimation; condensation and precipitation; infiltration and percolation; surface run-off; and plant uptake.

When scientists search for life on other planets, the first thing they look for is the presence of water. On Earth, water exists naturally in solid, liquid and gas states, and is essential to all forms of life. This motion-graphics based clip takes the viewer through the keys stages of the water cycle including: evaporation and transpiration; condensation, precipitation, and surface run-off. Show Less
