“ “ Ohio experiences a change in seasons Ohio experiences a change in seasons because of Earth’s tilted axis. When because of Earth’s tilted axis. When Ohio is tilted away from the Sun it gets Ohio is tilted away from the Sun it gets less concentrated sunlight, and it is less concentrated sunlight, and it is winter but when Ohio is tilted toward winter but when Ohio is tilted toward the Sun it gets more concentrated the Sun it gets more concentrated sunlight, and it is summer. Ohio sunlight, and it is summer. Ohio experiences summer in part III. Since experiences summer in part III. Since Earth is tilted on its axis, when it orbits Earth is tilted on its axis, when it orbits around the Sun some of the Earth around the Sun some of the Earth experiences summer while the rest experiences summer while the rest experiences winter.”experiences winter.”
