The Great Lakes • From largest to smallest they are: • Lake Superior--The largest freshwater lake in the world • Lake Huron • Lake Michigan • Lake Erie • Lake Ontario • 18,000 years ago glaciers covered the Midwest. • As they moved across the land they gouged enormous holes in the land. • The glaciers melted and filled these giant holes with water. • This is how the Great Lakes were formed.
Rivers • Midwest has many lakes and rivers • Ohio River forms the boundary between the Midwest and Southeast • Ohio River flows into the Mississippi River • Missouri River is the largest tributary of the Mississippi River • Tributary- a smaller river that flows into a bigger river • Thousands of years ago, glaciers carved deep trenches in the land. When the glaciers melted these “trenches” filled with water to become rivers.
