The basic theory of plate tectonics is that along seafloor spreading zones, the continents are separating from one another. As they spread apart, magma comes to the surface and becomes new continental crust. As the tectonic plates move away from spreading zones, they collide with one another.

Vast, circular to elliptical dark-colored areas on the moon called maria represent <u>very large impact</u><u> craters </u><u>filled with </u><u>basaltic lava</u>.
As the brightest and largest object in our night sky, the Moon softens the axial wobble of our home planet, making it a more habitable planet, resulting in a relatively stable climate. It also causes the tides, creating rhythms that have guided humans for thousands of years.
Without the Moon, a day on Earth would only last 6 to 12 hours. A year can be more than 1000 days. This is because the earth's rotation slows down over time thanks to gravity (or the gravitational pull of the moon). Without it, the days would fly by.
