Study Notes
Biomes
- A biome is a regional area characterized by the plants, animals, and climate in that area.
- There are five primary biomes: Grassland, Desert, Forest, Aquatic, and Tundra.
Tundra Biomes
- Characterized as a treeless polar desert.
- Located in high latitudes and can be divided into two categories: arctic tundra and alpine tundra.
- Temperatures in the tundra can reach -22 degrees Fahrenheit, with rainfall less than 6 to 10 inches per year.
- Permafrost is permanently frozen ground located under the soil, unique to this biome.
Arctic Tundra
- Covers one fifth of the surface on Earth, found at the North Pole above the tree line.
- Temperatures can reach -50 degrees Fahrenheit, with summers only 50 to 60 days in length.
- Harsh temperatures cause the land to be barren, with animals including arctic foxes, polar bears, and musk oxen.
Alpine Tundra
- Found further away from the poles, with higher temperatures and a wider range of precipitation.
- Summers range from 37 to 53 degrees Fahrenheit, and winters rarely below zero degrees Fahrenheit.
Grassland Biomes
- Located in middle latitudes, divided into savannas and temperate grasslands.
- Savannas are located near the equator, with warm year-round climates, covering over half of Africa and large portions of Australia, South America, and India.
- Temperate grasslands are found in regions including Argentina, Australia, and the central part of North America.
Desert Biomes
- Cover about one fifth of Earth's land surface, receiving very little precipitation.
- Four main types of deserts: hot and dry, semi-arid, coastal, and cold.
Forest Biomes
- Cover about one-third of Earth, found in various locations with varied climates.
- Four types of forest biomes: temperate deciduous forests, tropical rainforests, jungles, and taiga/boreal forests.
Aquatic Biomes
- The largest of all biomes, covering almost 75% of Earth.
- Can be divided into two main categories: freshwater and marine.
