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:
<u>Inversion is found in upper layer sf troposphere.</u>
Explanation:
- When there is a decrease temperature t every 3.5 degrees for every 100 feet. As when this normal cycle is present the air said to be unstable and constantly flows between the warm and cold areas.
- During inversion temperature decrease with the increasing altitudes. temperature inversion can occur in areas of coastal origins due to the upwelling of cold waters.
- Topography plays a role as cold and cool air flows from the mountain peaks down into valleys. This cold air then is pushed back due to the warm and lighter air mass and hence creating an invention.
- Inversions can also form in areas with significant snow cover as the ground is cold white color reflects most of the sunlight.

C. Physical
Explanation:
The Rio Grande river is an example of a physical boundary between two countries since it is a landform. Physical boundaries are very diverse and can include oceans, seas, mountains, rivers, and lakes, just to name a few of the many landforms that can make a physical boundary.
A cultural, geometric or religious boundary could perhaps be visible with the right type of map, but a river does not tell us anything about the religious makeup of a certain area, nor does it reflect the cultural of the inhabitants.
