Question

write a short note on lakes of North America

Answer 1

Answer:

Lakes abound in North America. Most of them are products of glaciation, which has had a vast effect on the continental drainage pattern—notably by widening the passes through the northern Appalachians and the Cordilleras and by forming big lakes in ice-deepened basins.

• The Great Salt Lake is a relic of Lake Bonneville, the ancient strandlines of which are up to 1,000 feet (300 metres) above the present shoreline.

• Similarly, present-day Lake Chapala in Mexico represents only a small portion of the large body of water that accumulated on the Mexican Plateau and whose level fluctuated during several pluvial periods.

. The contribution of all these lakes—and many more—to the drainage of North America has been outstanding.
