Abiotic Factors
Abiotic factors of a biome are non-living things in the habitat.
Some abiotic factors of the tundra are:
Some abiotic factors of the tundra are:
1.) Permafrost
Permafrost
A layer of subsoil, or the layer of subsoil directly under the surface that is permanently frozen. In other words, the ground is permanently frozen. Nothing is able to penetrate the permafrost. Soil is not living, so it is abiotic.
2.) Strong and Cold Winds
Wind
Weather is not living, so it is abiotic.
3.) A Small Amount of Precipitation
Rain
Rain, snow, sleet, and hail. Again, weather is not living. This makes this abiotic.
4.) A Little Amount of Sunlight
A Small Amount of Sunlight
Since it is northern, and at the top of the world, the sun doesn't reach it as much as the other places of the earth. Sunlight is not living either, making it abiotic.
5.) Pools of Water on the Surface in the Summer
Pools of Water in the Tundra
During the summer, even though the summer days are very short, the water gets through the top layer of soil, but isn't able to get through the permafrost. This forms pools of water on the surface of the permafrost. Water is not living, so it is abiotic.
