Grasslands have a high ranging temperature furing the year ranging from -40 degrees F in the winter to 70 degrees F in the summer.Most temperate grasslands the average rainfall ranges from 10-30 inches every year. In tropical and sub-tropical grasslands the average rainfall ranges from 25-60 inches per year. This is a big factor in deciding wether trees grow in the area (which is a big factor in deciding if an area is considered a grassland biome). The upper layers of soil are only moist part of the year and the lower layers are always dry which are diffivult conditions for a tree to grow in. There are said to be two real season which are the growing season and the dormant season. During the gowing season there is no frost and it is warm enough that plant life can grow. This lasts from 100 to 175 days. During the dormant season it is too cold for anything to grow.
