Earth has many different kinds of life. Having an atmosphere is crucial to life as we know it. Launching things into outer space from Earth is extremely expensive because of its gravity. Earthquakes occur when Earth's vast, massive plates grind past each other in a process known as plate tectonics. The Grand Mesa in Colorado is the largest flattop mountain in the world, encompassing more than 500 square miles and standing over 10,000 feet above sea level. Because the Moon was much closer to Earth back then, its magnetic field was close enough to serve as a literal shield and helped protect the atmosphere against those strong Solar winds.

The mesa is surrounded on three sides by major river valleys. Sediments drifted to the bottom of prehistoric seas and hardened there, forming layers that include a 1.25-billion-year-old limestone studded with fossils of algae, the earliest life recorded in the canyon. The dark, volcanic rock (basalts) on the cliff faces of some of the mesas creates an optical illusion that the high mesas are actually depressionsan illusion enhanced by the shadows the mesas cast to their northwest. Wind erosion abrades surfaces and makes desert pavement, ventifacts, and desert varnish. If you have two angles, you know the third, because the sum of the angles is 180 [degrees], Molnar told Live Science.
