Rainforest: Mission: Biomes - NASA Earth Observatory
The 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 …
The 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 ...
Tundra: Mission: Biomes - NASA Earth Observatory
Description. 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.
The Carbon Cycle - NASA Earth Observatory
The 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.
Desert: Mission: Biomes - NASA Earth Observatory
Desert 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!
Hunga Tonga-Hunga Ha‘apai Erupts - NASA Earth Observatory
2022年1月18日 · The volcanic island first rose from the sea in January 2015. Eruptive activity built up ash around a new volcanic cone and connected the older, more lava-based islands of Hunga Tonga and Hunga Ha‘apai to create Hunga Tonga-Hunga Ha‘apai. Signs of the island’s recent demise were easy for satellites to spot in the seas.
Coniferous Forest: Mission: Biomes - NASA Earth Observatory
Description. 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 ...
Planetary Motion: The History of an Idea That Launched the …
The 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 ...

Night Light Maps Open Up New Applications - NASA Earth …
2017年4月13日 · 2016 PNG. NASA scientists have released new global maps of Earth at night, providing the clearest-yet views of the patterns of human settlements across our planet. Satellite images of Earth at night—often referred to as “night lights”—have been a curiosity for the public and a tool of fundamental research for at least 25 years.
