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.

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.

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 ...

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. A biome is a community of plants and animals living ...

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.

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.

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 ...
