Because they exist in many countries and geographic locations, the average temperature of a grassland ranges greatly depending on its location.

The aims of this study were to analyze the spectral response features of grassland plants to mining dust and to predict the spatial distribution of dust retention using hyperspectral data. The temperatures can vary from a winter low of minus-40 degrees Fahrenheit in some regions to a summer high of more than 100 degrees Fahrenheit in other or even the same regions. Sage plants in Theodore Roosevelt National Park usually grow as a shrub or bush. for example, most grasses in grasslands have a sharp leaf blade which can injure animals if they try to eat it.

It's a little wetter than deserts, they have hot and dry summers, without enough rain the grasslands don't develop, and natural grass fires play an important role. Unfortunately, grasslands plants haven't that privilege. It is also cold- and heat-resistant. Soils of tropical grasslands may also be less fertile than comparable temperate grassland soils as a result of faster weathering rates under warm year-round temperatures and soils that are much often much older than in temperate grasslands. They can sometimes form mosaics with scrub and denser woodlands. Grasses survive the fires and grazing. 4. ASU - Ask A Biologist. However, human activities over the centuries altered its composition and today; it has become one of the most endangered of all the biomes in the world.Human activities like agriculture have also destroyed and reduced the biome to such a degree that it doesn't look appealing anymore and it has a lower biodiversity . We will learn a little more about flowers when we research insects! Similarly, the soil particles in this zone are smaller and finer compared to the lower horizons of the soil.
