A few questions on prairie crops and regions...?

Question

I have a social studies booklet to do and just need some answers for a few questions. First, how does climate affect prairie grain crops in Canada? What does too much rain cause? What does not enough rain cause?
Which countries buy grain from Canada?
And finally, are these places all land form types of regions: Swiss Alps, Sahara Desert, and the Great Lakes?

Thanks to anyone that helps =]

Answer 1

too much rain= flooding, erosion, crop dies
not enough rain= crop fails

The crop year ended on July 31 with record wheat sales to Indonesia and Mexico and the largest wheat shipments to Britain in 20 years. India became a major wheat customer for the first time in 10 years, while sales to the United States rebounded in the first full crop year since an American tariff wall, imposed in 2003, was lifted in early 2006.

Answer 2

Too much rain causes floodong hence reduced area seeded, disease in standing crops and lost grade in mature crops ready to harvest.
Not enough rain means reduced yield. Often protien in wheat goes up. If you are refering to global warming some ares can grow crop they couldn't grow before.
Canada sells a variety of grains and oilseeds to countries around the world. China being one of the major customers.

Answer 3

TOO MUCH RAIN CAUSES DISEASES SUCH AS SMUT WHILE TOO LITTLE MEANS THE WHEAT DOESN'T GROW
