24. Tides No moon

25. Tides With a moon

26. Tides • The moon’s gravity attracts the Earth and the oceans. • It makes the oceans bulge up on opposite sides of the earth. • The sun does this too, but it’s too far away to do much.

27. Tides This makes two high tides every day as the Earth rotates. With a moon

28. Tides • If the sun and moon are lined up, high tides are higher.

29. Tides • If the sun and moon are lined up, high tides are higher. ……

30. Tides • If the sun and moon are not lined up, high tides aren’t as high.
