Does The Sun Rotate On Its Axis?
what do axis mean?
i heard of sixaxis and fiveaxis
an axis is like a line going in a certain direction, both ways. Like on a grid, the horizontal one (left and right) is called the x-axis. And the vertical one (up and down) is called the y-axis.
The PS3 SIXAXIS controller is called that because it's motion sensing works on six axis's. It goes:
1. Up and down
2. Left and right
3. Foward and Back
4. You can rotate it foward and back
5. You can rotate it on its side (like so one handle is up in the air and the other is down on the ground)
6. You can rotate sideways (like if you had it flat on the ground and spinned it like spin the bottle)
All these axis's work together so you can move your controller in any way possible for it to work
the imaginary line around which the earth rotate?
Earth rotates around a geographic axis that runs through our south and north *geographic* poles (these are slightly different than the magnetic poles).
Our mass actually rotates around a separate axis set 33 feet from the geographic axis; this is called the "figure axis" and is the point of mass balance, not geodetic balance.
However! The answer you're looking for is the north-south geographic axis. The equator is just the line around the globe where Earth has its greatest diameter (latitude 0°.)
And, just because I'm answering... do not confuse "rotate" with "revolve." A planet/moon/etc. body *rotates* around its own internal axis. The same planet/moon/etc. *revolves* around another central body where the axis is outside of the planet -- more colloquially called "orbit." We revolve around the sun. But if you talk to a scientist and get your terms wrong, there will be confusion.
Does the earth really spin?
I can't believe I am asking this question but I am not a scientist. Does the earth spin or does it rotate around the sun? Why do we get winters and summers? If the earth is spinning, how come I can't feel it? OMG!!!!!!!!!!!!!!!!!
Earth both spins on its axis and revolves around the sun. You can't feel it because everything else (including the air within our atmosphere) is moving along with us.
We get seasons because Earth's axis is tilted and because our distance from the Sun changes as we go around it (our orbit is elliptical, not circular). "Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant."
What direction does Earth Rotate and Evolve around Sun?
What direction does Earth Rotate on its axis (counter clock or clockwise?) and what direction does Earth Revolve around the sun?
The Earth rotates and revolves both counterclockwise. If you were looking straight down on the north pole it would be spinning toward your left. Almost everything in our solar system revolves this way, although some bodies vary extremely on their individual axis. The bodies that do not revolve counterclockwise are said to be in "retrograde motion". Bodies that move in retrograde are usually getting closer and closer until eventually they reach the planets "roche limit" where their own gravity will no longer be able to hold them together, forming a ring around the planet. :)
What makes planet earth rotate the same way on its axis all the time? Whats is the cause and effect of this?
What causes the earth to rotate the same way every year? On its axis in 365 days causing our seasons? Is it the suns orbit? Or something else?
Things continue in a uniform state of motion unless some force acts to stop them--this is something that Isaac Newton taught us. That means that if something is spinning, it's in its nature to just keep on spinning unless something like friction slows it down. In the case of the earth, the gravitational tug of the moon actually DOES slow the earth's spin by a tiny amount, and in fact the earth has (very) gradually been slowing down over the past few billion years.
The seasons are caused by the tilt of the earth's axis. Beacause of the tilt, the latitudes in the earth's northern hemisphere are tipped more toward the sun in June, so they receive the sunshine at a more direct angle which makes it hot. In December, the northern latitudes are tipped away from the sun, making it colder.
