| Biosphere Mission Biomes @ NASA's Earth Observatory
Have you ever wondered what it would be like to live in a different part of the world? What would the weather be like? What kinds of animals would you see? Which plants live there? By investigating these questions, you are learning about biomes.

For Grades: 4-12 Changing Global Land Surface @ NASA's Earth Observatory
Human presence across the face of the Earth is substantial and growing. Increasingly, from the perspective of outer space we can see the "fingerprints" of human presence on our landscapes.
For Grades: 9-12 Phytoplankton @ NASA's Earth Observatory
Phytoplankton are microscopic plants that live in the ocean. There are many species of phytoplankton, each of which has a characteristic shape. Collectively, phytoplankton grow abundantly in oceans around the world and are the foundation of the marine food chain.
For Grades: 9-12 Tropical Deforestation @ NASA's Earth Observatory
The clearing of tropical forests across the Earth has been occurring on a large-scale basis for many centuries. This process, known as deforestation, involves the cutting down, burning, and damaging of forests.
For Grades: 9-12 Drought @ NASA's Earth Observatory
While much of the weather that we experience is brief and short-lived, drought is a more gradual phenomenon, slowly taking hold of an area and tightening its grip with time. In severe cases, drought can last for many years, and can have devastating effects on agriculture and water supplies.
