they're so high because when the sun, moon, and earth are in a line, their gravitational pull creates a tidal bulge on earth. during neap tides, the sun, moon, and earth are at a 90 degree angle, making more even tidal bulges, making high and low tides closer together than the spring tides.
There's a place in the Northern Territory or Western Australia where there are massive tidal changes of up to 12 m every day.
Abnormally low tidal range. (Neap tide)
The Moon affects the tides of this planet, much more than the Sun. It is the gravitational pull of those masses in space which pull the water of the oceans from the Earth and the Earth from the water. (There IS a tidal bulge on the same side as the Moon AND on the opposite side! And smaller ones towards and away from the Sun).
The Earth is getting very, very slightly farther away from the Sun over time, due to tidal forces.

The primary source of tidal effects on Earth is the Moon, and the Sun is #2.

A spring tide has the greatest tidal range. A neap tide has a smaller tidal range.
Tides are caused by the gravitational pull of the moon, rising and falling as the moon orbits the earth AND the earth turns.
The gravitational interaction of the Earth and Moon produces a number of effects. The most obvious of these is the orbital motion of the Moon around the Earth, but there is also a motion of the Earth around the center of mass of the Earth-Moon system, tidal effects on the Earth and Moon and professional effects on the Earth's axis of rotation.
Twice a month. When the moon is directly opposite the sun and when it is in line with the sun in relation to the earth. These are called spring tides.
Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation.
