Biomes

What's a biome?

A major regional or global biotic community characterized chiefly by the dominant forms of plant life and the prevailing climate.

What are different biomes?

Tundra- Is believed to be the youngest of all of them in the world. It was believed to have formed approximately 10,000 years ago. Approximately 20% or of the surface of the Earth falls into this category. You will find the tundra biome along the coastal regions of the arctic. The combination of polar air and arctic air masses dominate in this particular biome. There is a very long winter and it is cold and harsh. The summer is short and mild, but most experts don’t view it as a true summer season.

Taiga- This one is one that has very long and cold winters. They summers are short and they are cool in temperature. The cool air masses from the arctic can move in rapidly. The average temperature in the summer is from 64 degrees to 72 degrees. However, in the winter months it can be -14 degrees. Taiga biome makes up 29% of the world’s forest cover.

Temperate deciduous forest- In the polar front zone you will find the deciduous forest biome. The battle rages on between the tropical air masses and the polar air masses. The temperatures can drastically change from one day to the next. They can also change rapidly on the same day. There are distinct seasons where the summers are warmer than in the winters.

Scrub Forest- A scrub forest is one of the biomes that make up aridland. This type of biome also consists of desert and areas of low-lying, dense underbrush. It is an area of little precipitation, plenty of continuous winds, poor drainage and medium to poor soil quality. The plants and animals of the tropical scrub forest have adapted to flourish in this harsh environment.

Grasslands- Along certain areas of North America and Eurasia you will find grassland biomes. There are mountain ranges in place that prevent the ocean air masses from affecting these areas. As a result the polar air can become dominant, giving way to some colder temperatures in the winter months. However, in the summer the continental air mass is dominant. As a result there is some rainfall during the summer.

Desert- This is a biome that is very hot and dry. They are found at the lower latitudes, between the Tropic of Cancer and the Tropic of Capricorn. Light winds occur often which evaporates any type of moisture that is typically going to develop in them. The heat is very dry and that makes it hard for too many types of plants or animals to be able to survive in such biomes. Approximately 20% of the Earth falls into this category.

Tropical rain forest- Tropical rainforest biomes are found in the lower latitudes. The temperature is generally around 80 degrees. There is very high humidity too – from 77% to 88%. There isn’t a big change in seasons like there are with many other biomes. Instead, this is what you can expect day after day. It will rain just about every day due to the high humidity. That humidity mixes with the heat to create cumulus clouds. For millions of years it has been this way in this particular biome.
