The correct answer is - biomass from the decomposing grasses.
The Midwest is a region known for its highly fertile soil. The reason for this is that the weathered bedrock combines with huge amounts of biomass. The biomass is almost entirely form the grasses. The grasses grow naturally in this region and they dominate the landscape. They grow and die out relatively quickly, as most of those grasses are one season grasses. They manage to create very large amounts of biomass every year, and also they decompose very quickly. The grasses also are high in nutrients, so once decomposed, they give the soil a lot of nutrients as well, which makes it very fertile and suitable for agriculture.
Answer: low cost of living and mild climate
Explanation: Ap3x
Coalescence
Coalescing means the pulling together of separate masses to become one bigger mass.
Explanation:
As water vapor rises into the upper cooler atmosphere, it cools and condenses into moisture droplets. These tiny droplets collide with each other, due to gravity, vertical motions and wind, to form larger droplets. This is even enhanced if there are seed particles in the air that allows the formation of larger droplets. When the droplets get large enough for gravity to act on them, they fall as precipitation.
If there are strong updrafts, the cloud could carry even larger droplets before precipitation which is what happens in the case of thunderstorms.
