Land Biomes

These are the 8 different land biomes in order from coldest to warmest


Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead org

Coniferous Forest (also known as Taiga)

The Coniferous Forest is a forest of Conifers (too much to handle, isn't it?). A Conifer is a tree that produces its seeds in cones. The Pine tree is the most common example. Conifer leaves conserve water with the thick, waxy layer that covers their leave

Deciduous Forest (also known as temperate forest)

Deciduous forests can be found in the eastern half of North America, and the middle of Europe. There are many deciduous forests in Asia. Some of the major areas that they are in are southwest Russia, Japan, and eastern China. South America has two big are


Grasslands are characterized as lands dominated by grasses rather than large shrubs or trees. In the Miocene and Pliocene Epochs, which spanned a period of about 25 million years, mountains rose in western North America and created a continental climate f


The chaparral biome is found in a little bit of most of the continents - the west coast of the United States, the west coast of South America, the Cape Town area of South Africa, the western tip of Australia and the coastal areas of the Mediterranean.


A Hot and Dry Desert is, as you can tell from the name, hot and dry. Most Hot and Dry Deserts don't have very many plants. They do have some low down plants though. The only animals they have that can survive have the ability to burrow under ground. This

Tropical Rain Forest

The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly.
Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets

Aquatic Biomes



Freshwater is defined as having a low salt concentration�usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e, ocean). There are diffe


These regions range in size from just a few square meters to thousands of square kilometers. Scattered throughout the earth, several are remnants from the Pleistocene glaciation. Many ponds are seasonal, lasting just a couple of months (such as sessile po


These are bodies of flowing water moving in one direction. Streams and rivers can be found everywhere�they get their starts at headwaters, which may be springs, snowmelt or even lakes, and then travel all the way to their mouths, usually another water cha


Marine regions cover about three-fourths of the Earth's surface and include oceans, coral reefs, and estuaries. Marine algae supply much of the world's oxygen supply and take in a huge amount of atmospheric carbon dioxide. The evaporation of the seawater

Aphotic Zone

The deepest layer of the world's oceans gets no sunlight at all. This dark ocean layer is called the midnight zone or the aphotic zone (aphotic means "no light" in Greek). The depth of this zone depends on the clarity or murkiness of the water. In clear w

Coastal Zone

The coastal oceans of the world, while amazingly diverse, are also fairly similar. Because these zones are close to land, there are certain related plants and animals that have adapted to these conditions, and are likely to be found around the globe.

Intertidal Zone

The intertidal zone is defined as the area between the high tide and low tide mark.
Organisms that live in this zone have to deal with difficult environmental conditions. They have to deal with being both submerged in sea water and exposed to the air. The

Coral Reef

Coral Reefs
Coral Reefs have been called the rainforests of the ocean because of their rich biodiversity. Unfortunately they are also in becoming increasingly threatened. Not only is global warming going to affect the survival of coral reefs, but other hu


Estuaries are bodies of water formed where freshwater from rivers or streams connect with salt ocean water. The mixed water is called brackish, and the salinity may fluctuate dramatically for example depending on freshwater input from rains and waves and
