Was the earths axis ever straight?

Answer 1

Basically, if the Earth were not tilted, the same amount of sun would fall on all parts of the Earth each day of the year. The polar regions would continue receiving less solar energy than the tropics on each side of the equator, but the Arctic and Antarctic would not have times of the year when the sun never sets and times when it never rises. Also, each day of the year would see a little more than 12 hours of daylight and a little less than 12 hours of darkness

Answer 2

The sun is directly overhead. This occurs along the tropic of cancer during the summer solstice, and along the tropic of Capricorn during our winter solstice (though it would be the beginning of summer in that hemisphere).

In between the tropics the sun passes directly overhead twice a year.

Answer 3

The Earth's axis IS at right angles to the sun's rays at the time of the March

and September equinoxes.

If the Earth's axis were also perpendicular to the ecliptic plane, then it would

be at right angles to the sun's rays ALL the time. In that case ...

-- There wouldn't be any seasons. Each area of the earth would keep its own

climate all year long.

-- There would be 12 hours of daylight and 12 hours of night, all year and at all latitudes.

Answer 4

All axes are straight. - If the Earth's axis were perpendicular to the plane of orbit, there would be no noticeable seasons.

Answer 5

The Earth's axis has always been tilted. This tilt is what causes the changing seasons as the Earth orbits the sun.

Answer 6

There is always 50% of the sun facing the earth, and

there is always 50% of the earth facing the sun.

Answer 7

Answer 8

nothing would change

Answer 9

Then there would not be any seasons.

Answer 10

yes
