What causes the tides? It is the gravitational attraction of the sun and moon that cause waters of the ocean to raise and lower at different parts of the earth. Tides occur in oceans, and to a much smaller extent, tides also occur in large lakes, in the atmosphere, and within the solid crust of the earth.
high tides are high water level they are called spring tides and low tides are low water level they are called neap tides. high tides and low tides occur when the sun, earth a â¦ nd the moon are inline. Low tide is when the moon pulls the sea out further creating more  sand â¦ space.     High and low tides are caused by the positions of the Sun and Moon  relative to your position on the Earth's surface.
