The Geography of Ohio
Unit 1 Lesson 1
Ohio in the World
• Ohio is part of the North American continent.– Continent one of the seven largest land
areas on Earth
• Ohio is one of the 50 states that make up the United States of America.
• Ohio is just south of Lake Erie, one of the Great Lakes.– Lake Erie forms part of the border between
Ohio and Canada.
Ohio in the World
• Five states surround Ohio– Pennsylvania (PA)–West Virginia (WV)– Kentucky (KY)– Indiana (IN)–Michigan (MI)
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.)
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
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
Ohio’s Regions
• Till Plains– 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.
Ohio’s Regions
• Lake Plains– Northern Ohio– Glaciers formed flat land– Northern edge of this region is Lake Erie• Formed by melting glaciers

A Midwestern State
• Ohio is one of the 12 states that make up the Midwest– Ohio is the farthest east
• One of the six Midwestern states that border the Great Lakes
Ohio’s Climate
• Climate the kind of weather a place has most
• Ohio has a temperate climate.– neither very hot nor very cold– Temperatures at times can be very hot or
very cold thought depending on the season
• Winters cold, snowy– Snowiest area is the northeast
• Summers typically hot and humid
Lake Effect Snow
Ohio’s Climate
• Ohio receives about 40 inches of precipitation each year– Precipitation water that falls to Earth’s
surface as rain, sleet, hail, or snow
• Many plants grow in Ohio–More than 2,300 species of wildflowers
grow in Ohio
