Question

compare the western parts of the Prairies with the eastern parts?

Answer 1

Prairie in North America is usually split into three groups: wet, mesic, and dry.[11] They are generally characterized by tallgrass prairie, mixed, or shortgrass prairie, depending on the quality of soil and rainfall.

Wet Edit

In wet prairies, the soil is usually very moist, including during most of the growing season, because of poor water drainage. The resulting stagnant water is conducive to the formation of bogs and fens. Wet prairies have excellent farming soil. The average precipitation is 10–30 inches (250–760 mm) a year.

Mesic Edit

Mesic prairie has good drainage, but good soil during the growing season. This type of prairie is the most often converted for agricultural usage; consequently, it is one of the most endangered types of prairie.

Dry Edit

Dry prairie has somewhat wet to very dry soil during the growing season because of good drainage in the soil. Often, this prairie can be found on uplands or slopes. Dry soil usually doesn't get much vegetation due to lack of rain.[12] This is the dominant biome in the Southern Canadian agricultural and climatic region known as Palliser's Triangle. Once thought to be completely unarable, the Triangle is now one of the most important agricultural regions in Canada thanks to advances in irrigation technology. In addition to its very high local importance to Canada, Palliser's Triangle is now also one of the most important sources of wheat in the world as a result of these improved methods of watering wheat fields (along with the rest of the Southern prairie provinces which also grow wheat, canola and many other grains). Despite these advances in farming technology, the area is still very prone to extended periods of drought, which can be disastrous for the industry if it is significantly prolonged.[13] An infamous example of this is the Dust Bowl of the 1930s, which also hit much of the United States great plains ecoregion - contributing greatly to the Great Depression.

Answer 2

Prairies are known as a part of temperate grasslands and savannas. Prairies are land with composition of grasses as main vegetation. Prairies covers the vast part of North America.  

Prairies are known for its versatile climate and high speed wind.  

• Western prairies are mostly drier when they get closer to the desert.
• Eastern prairies are mostly a moisture region.
• Rainfall tends to be low in western Prairies when compared to Eastern prairies.
