Where Does the Moon Pull the Ocean?The moon's gravity helps pull ocean water into tides, so shorelines rise and fall in a repeating pattern.
1. At dawn, Mira crouched beside a rocky beach, where the ocean had slipped far from shore. She held a shell over the damp sand. “Where does the moon pull the ocean?”
2. She placed three smooth shells along the wet edge and faced the sea. “If the water comes back, I will know where it reaches.”
3. By noon, a silver ribbon of water curled around the first shell. Mira stood on dry sand and checked her little row. “The ocean has climbed higher, but where is it going?”
4. By late afternoon, water covered all three shells and filled the pools between the rocks. Mira moved her bucket to a safe, dry place and watched the shore spread wide. The water was not lost. It was visiting.
5. When the round moon rose, Mira found a bright path on the water. She touched the wet sand and whispered, “Are you pulling the ocean toward you?” The moon stayed silent, but the tide reached its highest mark.
6. At dawn, the water had fallen away again. The three shells lay in a neat line, and dark bands on the sand showed yesterday’s high edge. Mira knelt between the two shorelines. “It came in, and it went out.”
7. Then Mira understood a small, mighty secret. The moon’s gravity reaches across space and tugs on the ocean water. That tug helps make broad swells, and Earth turns beneath them.
8. Mira tucked a shell into her satchel and watched the new waterline touch the sand. “Now I know where the moon pulls the ocean. It pulls on ocean water all around Earth.” The moon’s gravity helps pull ocean water into tides, so shorelines rise and fall in a repeating pattern.
