6. Ohio’s Natural Wonders
35 states are larger than Ohio
Even though Ohio is a small state, it has different natural regions.
Natural region  an area made up of places that share the same natural features (similar landforms, bodies of water, etc.)

7. Ohio’s Natural Wonders
Ohio’s natural regions formed more than 10,000 years ago.
Glaciers (huge sheets of ice) covered much of the land and over time, slowly moved.
As a result, the land changed.
Glaciers flattened mountains and carved valleys.
When they melted, they left behind till.
Till  a mixture of clay, sand, and rock that makes soil very rich

8. Ohio’s Regions Glaciated Appalachian Plateau
Central and northeastern Ohio
Glaciers moved over the area and flattened the land.
Till
Unglaciated Appalachian Plateau
Southeastern Ohio
Glaciers did NOT move over this part of the state
Steep hills, deep valleys, rivers, waterfalls

9. Ohio’s Regions Till Plains Bluegrass West of the Appalachian Plateau
Plain  area of flow, flat land
Named from the till in the area
Bluegrass
Southeastern Ohio
Triangle-shaped area between the Till Plains and Appalachian Plateau
Ohio River forms the southern border of this region
Much of the soil has washed away.

10. Ohio’s Regions Lake Plains Northern Ohio Glaciers formed flat land
Northern edge of this region is Lake Erie
Formed by melting glaciers
