They are common in areas characterized by mild wet summers and long, cold and dry winters.Grassland biomes typically occur in areas that are drier than regions ideal for forests. Temperate forests occur in eastern North America, western Europe and other areas with a temperate climate. Climate is primarily a matter of atmospheric processes while biomes are a matter of biology and ecology. Grassland biomes became widespread in the Miocene 25 million years ago in western North America as high mountains formed, changing the climate and causing the decline of primeval forests.Desert biomes consist of the plants that thrive in regions with very low precipitation levels. These include the following.Climate is the average weather of a region over a long period of time. Regions known for having dry climates include the Saharan region of Africa, the American Southwest and the Atacama Desert in Chile.Temperate climates have temperatures that are typically lower than tropical or dry climates. Desert biomes are found in North Africa, the American Southwest, and other areas with low precipitation. The vegetation that exists in tundra also tends to be fairly simple in its structure.Freshwater biomes include plants that exist near or within freshwater bodies such as lakes, rivers, and ponds.Marine biomes include oceans, coral reefs, and estuaries. They are characterized by very cold summers and winters. A recent example of climate change is global warming, a trend first discovered in the 1960s, in which global average temperatures have been increasing steadily due to a build-up of carbon dioxide and other greenhouse gases in the atmosphere. Regions with tropical climates are typically rich in vegetation and animal life. Polar climates also tend to be very dry, but nonetheless are covered in ice and snow because the ice does not melt easily. Forest biomes can be temperate, tropical, or boreal. Because of these low precipitation rates, vegetation is typically scarce. Please note: comment moderation is enabled and may delay your comment. They are characterized by clearly defined seasons and a distinct winter season which can include snow.Tropical forests occur in regions between 23.5 degrees north and 23.5 degrees Boreal forests occur between 50 and 60 degrees latitude and form one of the largest terrestrial biomes. A Biome is a biological community based on similar vegetation spread out over a region that can encompass a limited geographic area or an entire planet. Areas with continental climatic conditions will have warm summers and Polar climates, as their name implies, occur in the polar regions in the northern and southern hemispheres. Temperate climates are common in regions such as the Mediterranean basin, parts of eastern and central China, and the southeastern U.S.Continental climates are common in the interiors of continents, hence their name. Their summers can be warm or hot and their winters tend to be mild. Climate refers to the average weather patterns that occur within a region over a long Climate is traditionally classified in terms of the average annual precipitation, monthly precipitation, and atmospheric temperature.
