Answer:
soil is formed by the rocks erotion
Explanation:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material
Fossilization is a process that requires certain conditions so that it can take place. The climate is very important, a hot and wet place is not a place where there's a chance of finding fossils, while the places with permafrost are a much better candidate because the bacteria can not dissolve the organisms. The pressure also can play a vital role. A place that manages to keep the organisms safe from outside influence, like the tar pits, are excellent preservers. Also the structure of the organisms play a key role, a boneless organism is very hard to preserve and be fossilized, while an organism with bone structure has a bigger chance of being preserved.
I think it’s all except the second one and the last
The reason why the Midwestern United States have a very fertile soil, but Canada doesn't, despite both of them being covered by glaciers until relatively recently, and both having the same age of soil, is the climate and vegetation.
Canada is much colder than the Midwest, its winters are longer, and the summers mild, while the Midwest has higher temperatures, prolonged period of drought, and seasonal rainfall.
Because of this, Canada has been covered by coniferous forests. They leave relatively little biomass, and also the climate is making the decomposition of the biomass very slow, thus resulting in relatively poor soil quality.
In the Midwest, the climate is perfect for the development of the grasslands. The grasses grown and die each year. They live a lot of biomass, and the higher temperatures contribute that the biomass decomposes pretty quickly, thus resulting in good quality soil.
