This is in contrast to uniformitarianism that states that slow incremental changes made the Earth like it is today. Changes like erosion.

Can you describe how the motion and relative positions of the Earth, the Moon, and the Sun affect tides?
Strike441 [17]
<span>"The moon is a major influence on the Earth’s tides, but the sun also generates considerable tidal forces. Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides. When the sun, moon, and Earth are in alignment, the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides."
