What are the effects the sun has on the earth?
The Sun is what keeps the Earth in orbit.
Also the Sun is the source of heat and light for the planet.
A smaller effect is that the Sun helps to cause tides, but the Moon is more
the sun gives us the heat for the day.
in some parts of the world the curve is closer to the sun so it is hotter there
The moon does not have a greater effect on the earth than the sun, the moon effects the earth in a different way: The sun effects the earth by locking it in a gravitational orbit through the force of intertia, and effecting it's temperateness and density. The moon effects it on a closer short term basis by manipulating ocean and weather conditions.
When Earth is closest to the sun the northern hemisphere is in winter Given the effects of precession will this still be the case in 13000 years?
For one, it creates seasons. Based on the Earth's tilt, as the Earth orbits around the sun, there are periods where one half of the Earth is closer to the sun than the other and vise versa, creating the four seasons we recognize. It has also been the basis for our calendar in which one year equals one revolution around the sun. The spinning alone of the Earth as it goes around the sun has…
Yes, there is a gravitational pull that works both ways. Just as the moon is held in orbit by the gravitational pull of the Earth, likewise the gravitational pull of the moon has its effect on the Earth, most commonly seen in its effects on the tides of the ocean. No doubt the gravitational pull of the Sun also effects ocean tides and other unseen effects.
When a cme occurs on the sun why does it take a couple of days for its effects to be noticed on earth?
There are two dominant effects of the Sun on the planets in the Solar System. It binds them into their orbits gravitationally, and it warms them with its radiation. It also provides light, presumably mainly of interest to us here on Earth, and the Solar Wind of particles from the Sun bombards our atmosphere continually sometimes causing electrical effects in satellites and on the ground.
You can only see the effects of the earth in motion. You can see it in the distance above the horizon the sun travels at different times of the year. For example, during winter in the Northern hemisphere, the sun is low in the southern sky. In summer, the sun travels higher above the horizon. You can also see its effects relative to constellations in the sky, which appear to travel across the sky also…
The distance from the sun to the perihelion of the earth's orbit, the point in the orbit that is closest to the sun, is 96.71% of the distance from the sun to the aphelion of the earth's orbit, the point in the orbit that is farthest from the sun. The seasonal effects of that difference are insignificant compared to the effects of the tilt of the earth's rotational axis with respect to the plane of…
How can the sun shine on different parts of the earth if it can only shine on one part of the earth at a time?
Every particle of mass in the universe, from the largest galaxy to the smallest piece of the smallest atom, has gravity. There's a pair of forces between every two of them, trying to pull them together. If there were no forces of gravity between the sun and other things, then the Earth and other planets could not stay in orbits.
They predict that the earth should begin feeling the the effects of our Sun expanding as it exhaust its supply of hydrgen starting in about 900 million years or so. The earth could get some more time by moving away from the Sun as the Sun loses more and more mass. But, the end will come not long afterwards anyway.
Gravity causes force that pulls every two masses together. It's the force of gravity between the sun and earth that keeps the earth in orbit around the sun. Same goes for the other planets. The force of gravity is also what holds you on the earth. Gravity is everywhere, and you see the effects wherever there are two masses.
When the Moon and the Sun are on the same side of the Earth, or on opposite sides of the Earth (i.e., full moon or new moon), their effects are in the same direction, and the tides are stronger (spring tides). When they are at right angles, their effects will partially cancel, and the tides are weaker (neap tides - not sure about the spelling).
It does. Earth is moved by the gravity of the sun and, to a lesser degree the moon. We are move by almost the same amount and so we move with Earth. Since Earth's surface is our point of reference and we are moving with it, we don't notice it. We observe the effects of the gravity of the sun and moon in the tides.
There is no force to make the Earth move closer to the Sun. You and I see such things as swinging around a ball on a string, It will stop moving and fall, if let alone, because of the effects of friction and gravity. But between Earth and Sun, there is nothing much to create friction, so that isn't a factor. And the physicists tell us that the Earth is constantly, forever, 'falling' in a…
