Q:

What are lunar tides?

A:

According to Science and the Sea, lunar tides are the most common tides and are caused by the Moon's gravity. Although the Sun's gravity is stronger, it is farther from the Earth than the Moon, which is why lunar tides are more than two times stronger than solar tides.

Science and the Sea, a production of The University of Texas Marine Science Institute, explains that lunar tides are formed when the gravity of the Moon pulls more strongly on the side of the Earth facing it and creates bulges in a body of water. When the Earth rotates on its axis, the bulges also move and cause high tides when they hit land. Low tides are created halfway between the high tides when the water is at its lowest level.

  • Q:

    How do the tides work?

    A:

    According to the National Oceanic and Atmospheric Administration, the tides are caused by the gravitational force that pulls on the water and the forces exerted by the moon and the sun. The gravitational pull of the moon cause the ocean to bulge out in its direction, while another bulge occurs on the opposite side of the earth.

  • Q:

    How often do tides occur?

    A:

    Ocean tides are caused by the gravitational pull of the Moon and Sun. Due to the rotation of the Earth, locations will experience two high and two low tides each day. An alignment of the Sun and Moon will result in more extreme tides, known as spring tides.

  • Q:

    Where does tidal energy come from?

    A:

    Tidal energy comes from the rising and falling of oceanic tides, where water moves because of the gravitational relationship between the Earth and the moon. The Earth's rotation is also a component of tidal energy. Tidal power is a promising form of energy because it is renewable and widely available.
