Could the Earth actually stop spinning? More importantly, what would happen if the Earth stopped spinning? Read on for everything you need to know about why the Earth spins, if the blue marble could actually stop spinning, and what would happen if it did.
The Earth has spun on its axis since the planet came into being more than 4. Billions of years ago, the solar system was born out of a nebula, which is a giant cloud of gas and dust.
The nebula first formed a star, and gravity caused the star to move in a circular orbit. This situation for the Earth is not the condition of 'stopped' rotation, but it is as close as the laws of physics will let the Earth get.
If it stopped spinning completely During daytime for 6 months, the surface temperature would depend on your latitude, being far hotter that it is now at the equator than at the poles where the light rays are more slanted and heating efficiency is lower.
This long-term temperature gradient would alter the atmospheric wind circulation pattern so that the air would move from the equator to the poles rather than in wind systems parallel to the equator like they are now. The yearly change in the Sun's position in the sky would now be just its seasonal motion up and down the sky towards the south due to the orbit of the Earth and its axial tilt.
As you moved along constant lines of Earth latitude, you would see the elevation of the Sun increase or decrease in the sky just as we now see the elevation of the Sun change from a single point on the Earth due to the Earth's daily rotation.
It appears not. But until about three million years ago, North and South America were separated by an ocean, and even after the Isthmus of Panama formed, the tropical forests where the South American monkeys had evolved did not exist farther north.
Some populations may have tried moving northward, but not in large enough numbers to take hold. Q: Was there an Ellis Island equivalent on the West Coast, some central processing place for immigrants?
Yes: Angel Island Immigration Station in San Francisco processed about a million immigrants, most of them from Asian countries, from to Angel Island was built primarily to enforce the Chinese Exclusion Act of , which barred almost all immigrants from China, and the center subjected new arrivals to intense interrogations and invasive medical exams.
Some , Chinese were detained there, sometimes for years, and many of them wrote poignant notes and poems on the walls, says Theodore S.
