Desert: Mission: Biomes - NASA Earth Observatory
Description. 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.
Rainforest: Mission: Biomes - NASA Earth Observatory
Description. There are two types of rainforests, tropical and temperate. Tropical rainforests are found closer to the equator where it is warm. Temperate rainforests are found near the cooler coastal areas further north or south of the equator.
Temperate Deciduous Forest: Mission: Biomes - NASA Earth …
The average daily temperatures range between -30°C (-22°F) and 30°C (86°F) with a yearly average of 10°C (50°F). Hot summers and cold winters are typical in this biome.
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.

Planetary Motion: The History of an Idea That Launched the …
Many ancient and medieval cultures believed the stars and the planets rotated around a fixed Earth. The complex motions of the planets—which sometimes move backwards across the sky (retrograde motion, shown in the photo)—led Renaissance astronomers to question this geocentric theory.These astronomers discovered the laws of orbital mechanics, transforming natural philosophy into the ...
Coniferous Forest: Mission: Biomes - NASA Earth Observatory
The average temperature in winter ranges from -40°C (-40°F) to 20°C (68°F). The average summer temperatures are usually around 10°C (50°F). 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 ...
The Carbon Cycle - NASA Earth Observatory
Carbon flows between the atmosphere, land, and ocean in a cycle that encompasses nearly all life and sets the thermostat for Earth's climate. By burning fossil fuels, people are changing the carbon cycle with far-reaching consequences.
Global Maps - NASA Earth Observatory
Chlorophyll. Chlorophyll is used by algae and other phytoplankton--the grass of the sea--to convert sunlight and carbon dioxide into sugars. These maps show chlorophyll concentrations in the ocean, revealing where phytoplankton are thriving.
Dark Nights in Georgia - NASA Earth Observatory
2024年10月1日 · Hurricane Helene’s winds surged in strength as the storm churned over unusually warm waters in the Gulf of Mexico and closed in on the Florida Panhandle and southern Georgia on September 26, 2024. When the deadly Category 4 storm struck Florida’s Big Bend area and then pushed north, winds in some areas exceeded 140 miles per hour (225 kilometers per hour)—strong enough to snap trees ...
