Q:

What are some abiotic factors of temperate grassland?

A:

Quick Answer

The abiotic factors of temperate grasslands include low rainfall, moderate humidity, large temperature differences between winter and summer, seasonal fires and rich nutrients in the soil's upper layers. Temperate zones are regions between the tropics and poles, and abiotic factors are an ecosystem's nonliving parts.

Full Answer

Climate varies widely among temperate grasslands. During winter, temperate regions can descend to 40 degrees Fahrenheit, whereas during summer, these regions can reach 100 degrees or higher. Temperate grasslands experience 20 to 35 inches of rainfall per year. Where heavier rainfall occurs, the grasses grow taller.

Another abiotic factor of grasslands is the bedrock on which the soil sits. The type of bedrock affects the nutrients available in the soil for grasses and other life forms to consume. Temperate grassland soil is typically dark and deep.

Grasslands form in regions that don't have enough moisture to sustain forests, but which have enough rainfall to support greater amounts of plants and animals than deserts. Additionally, fewer trees grow in grasslands due to the lower layers of soil lacking the richness to support them. Frequent fires in temperate regions can also prevent trees from flourishing, as well as animals that graze tree seedlings before they can mature.
