Of course, occasionally these forming objects happen to attract something that's big enough to knock it off-kilter. That's what probably happened to the earth, after it was already large enough to start rotating. Actually, Wilson says it probably took several substantial impacts to whack the earth into the position it's in today.
Incidentally, back in the "old days," the earth used to rotate a lot faster—once every 6 to 10 hours at the start of the solar system—and the moon's gravity has played a big role in slowing us down to It's a good thing too, because a 6-hour day would certainly lead to an awfully hectic work week.
Now try and answer these questions:. The Nine Planets , created by astronomer Bill Arnett, has this feature on the earth and its general characteristics. See the Tool. See the Collection. See the Lesson. Photo Credit: Clipart. Aquarius is visible in the night sky, now in September, so does that mean that the map is showing the September equinox?
Actually it means that it can't be September, because Aquarius is in the night sky, meaning that it is not near the Sun. For Aquarius to be up during the day and therefore near the Sun we have to go to six months from September, to March. So the map represents the sky sometime around March How many hours of sunlight will there be on this day? Explain why, and include a diagram. There will be exactly 12 hours of sunlight on this date, because it is an equinox which means equal night.
Due to the In the Northern Hemisphere the day grows longer from December 21 until June 21, and then gets shorter again.
This is because the North Pole the northern part of the axis is pointed as far away from the Sun as it can get on December 21, and is pointed towards it on June 21 see diagrams 2. Halfway in between on March 21, the tilt is neither towards or away from the sun, so on that day, everywhere on Earth gets the same amount of daylight, exactly half of the day: 12 hours.
Label roughly where you expect the Sun to be one week later, and explain why. As the earth travels around the sun during the year it maintains this tilt. Because of this tilt, in the summer we north of the equator are slanted more directly towards the sun so it's hotter. In the winter, we're slanted away so the sun's rays are less direct, making it colder.
Has the earth's axial tilt changed? Asked by: Deonte Johnson. How does Earth's tilt affect climate? What would happen if Earth's tilt was 90 degrees? What if the Earth's tilt was 10 degrees? What would happen if the Earth's tilt decreased? Why does the earth's axial tilt change? Why does the earth's tilt change? How many degrees does the earth tilt?
How much does the earth tilt between summer and winter? What if Earth's tilt was 45 degrees? Why does Neptune's tilt give it four seasons? What would happen if Earth's axis of rotation were tilted at a lesser angle?
The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree or so. This tilt is what gives us seasons. Answer: The fact that we have seasons on Earth tells us that our planet does not rotate on its axis in the same plane that it orbits the Sun. Recent research by NASA found that the wobble of Earth as it spins is broken up into three primary factors: glacial rebound, melting of ice, and mantle convection.
