Tectonic plate boundaries, like the San Andreas Fault pictured here, can be the sites of mountain-building events, volcanoes, or valley or rift creation. The theory, which solidified in the s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes. These plates lie on top of a partially molten layer of rock called the asthenosphere. Due to the convection of the asthenosphere and lithosphere, the plates move relative to each other at different rates, from two to 15 centimeters one to six inches per year.

Wegener proposed the idea that the continents used to fit together like a jigsaw puzzle, this was named Pangaea Smithson et al, This process was called continental drift which was proposed in
Gopnik observes that children as well as adults can use counterfactual thoughts and knowledge to look for different possibilities.

Those questions of what is beyond of the reason of science is another possible world that one creates. The possible world of what is the other explanation of how Earth was created besides the scientific one.
