Gravity pushes extra masses of water and earth into a bulge, or "spare tire" around our planet. At the equator, the circumference of the globe is 24,901 miles (40,075 kilometers), according to Space.com. Bonus fact: At the equator, you would weigh less than if standing at one of ...
temperature differences, the Earth’s rotation, and even the moon’s gravity tracing the coastlines. By acting as a conveyor belt, these currents transport warm water and precipitation from the equator toward the poles while bringing cold water...
Well, that’s a complicated topic because of all the different pieces of (mis)information floating about. In 1886, John Joly theorized that contact between a surface and ice generates sufficient heat via pressure to create water. Another theory predicts that friction between the objects forms a ...
In 2014, scientists experimented "supercritical" water, a state of water that occurs when it is compressed to a pressure of 217 atmospheres and heated above 373 degrees Celsius. When mixed with organic material, it creates a liquid-like gas that creates a burning effect, though with no flame....
gravity is not the same all overand you would weigh slightly more at Earth's poles than at the equator. There are also places where gravity is extremely different, such asHudson Bay in Canada. Scientists believe convection currents from Earth's mantle or Earth reacting to the pressure of ...
The leading theory is that Mars' light gravity, coupled with its lack of global magnetic field, left the atmosphere vulnerable to pressure from the solar wind, the constant stream of particles coming from the sun. Over millions of years, the sun's pressure stripped the lighter molecules from ...
Saturn radiates two to three times as much energy as it receives from the sun. The bulk of this energy comes from friction generated by helium rain. Helium condenses in the cooler upper layers of the atmosphere and gravity pulls it toward the core. It generates heat by rubbing agains hydrog...
Jupiter is believed to have played akey rolein the formation of the Solar System, as its massive gravity influenced the orbits of other objects and prevented the formation of a planet in the asteroid belt between Mars and Jupiter. Despite its massive size, Jupiterrotateson its axis at an incr...
Red Giant stars are cool stars that are no longer on the Main Sequence as they have used up all their hydrogen and are now fusing helium into more complex molecules. They grow as outward pressure overrides the inward force of gravity. ...
One theory about the origin of Saturn’s rings is that they’re remnants of moons that were torn apart by Saturn’s gravity. This could be why the rings are composed mainly of water ice, a common material in moons. 52. Saturn’s moon Epimetheus shares its orbit with Janus. ...
