Rainforest: Mission: Biomes - NASA Earth Observatory
WEBThe tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers. The top layer or canopy contains giant trees that grow to heights of 75 m (about 250 ft) or more. This layer of vegetation prevents much of the sunlight from reaching the ground.
Temperate Deciduous Forest: Mission: Biomes - NASA Earth …
WEBThe deciduous forest regions are exposed to warm and cold air masses, which cause this area to have four seasons. The temperature varies widely from season to season with cold winters and hot, wet summers. The average yearly temperature is about 10°C. The areas in which deciduous forests are located get about 750 to 1,500 mm of precipitation ...
Desert: Mission: Biomes - NASA Earth Observatory
WEBDesert biomes are the driest of all the biomes. In fact, the most important characteristic of a desert is that it receives very little rainfall. Most deserts receive less than 300 mm a year compared to rainforests, which receive over 2,000 mm. That means that the desert only gets 10 percent of the rain that a rainforest gets!
The Carbon Cycle - NASA Earth Observatory
WEBThe Slow Carbon Cycle. Through a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. On average, 10 13 to 10 14 grams (10–100 million metric tons) of carbon move through the slow carbon cycle every year.
Tundra: Mission: Biomes - NASA Earth Observatory
WEBDescription. The tundra is the coldest of the biomes. It also receives low amounts of precipitation, making the tundra similar to a desert. Tundra is found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia. Much of Alaska and about half of Canada are in the tundra biome.
Mission: Biomes - NASA Earth Observatory
WEBBy investigating these questions, you are learning about biomes. A biome is a community of plants and animals living together in a certain kind of climate. Scientists have classified regions of the world into different biomes. Your mission, should you choose to accept it, is to investigate biomes, then test your knowledge about the biomes by ...
Planetary Motion: The History of an Idea That Launched the …
WEBThe ancient Greek philosophers, whose ideas shaped the worldview of Western Civilization leading up to the Scientific Revolution in the sixteenth century, had conflicting theories about why the planets moved across the sky. One camp thought that the planets orbited around the Sun, but Aristotle, whose ideas prevailed, believed that the planets ...
Coniferous Forest: Mission: Biomes - NASA Earth Observatory
WEBDescription. The coniferous forest is sandwiched in between the tundra to the north and the deciduous forest to the south. One type of coniferous forest, the northern boreal forest, is found in 50° to 60°N latitudes. Another type, temperate coniferous forests, grows in lower latitudes of North America, Europe, and Asia, in the high elevations ...
Volcanoes - NASA Earth Observatory
WEBJun 28, 2018 · Plumes of volcanic material traveled by air and by sea as the small Pacific island erupted in June 2024. A volcanic fissure on the Reykjanes peninsula came alive again with voluminous, vigorous flows. The latest fissure eruption on Iceland’s Reykjanes peninsula was the largest of four recent bouts of activity near the town of Grindavík.
