Polar Caps on Mars?

Question

Which polar caps, northern or southern, is thicker and more extensive in the winter...What two reasons cause more extensive size of the polar cap?

Answer 1

I appreciate your curiosity, but I don't care about the polar caps on Mars. The space race/exploration has gone far enough. There are way more things that need to be taken care of here on earth.

Answer 2

The Northern Cap is made up of a larger portion of water ice (as opposed to dry ice), and tends to grow and recede more during the Martian year. Much like Earth - Mars has (or had) more water in one hemisphere over the other, after it began to dry, the water dispersal stopped, and one polar cap retained more than the other.
So, the two reasons are, it has more water ice, and this is so because the southern hemisphere on Mars has more elevation than the north.

Answer 3

2 issues: First, there is not any genuine data of water interior the Martian Polar caps (they're frozen Carbon dioxide----dry ice) Any water we are able to locate on Mars may well be subsurface water. 2d, the capability costs of an area probe at a severe inclination to the ecliptic (the path the planets persist with often correct to the sunlight) may well be prohibitive. So why deplete that gigantic greater advantageous attempt to look at something you will locate interior an ice cream wagon?

Answer 4

The rotational axis of Mars is tilted at about the same angle as Earth, and that causes seasons. But Mars has a much more elliptical orbit than Earth, so its distance from the Sun varies much more than the Earth. Unlike Earth, where distance from the Sun is almost constant and not a factor, Mars gets a significant seasonal effect from its changing distance from the Sun. The pole that is tilted away from the Sun when Mars is farther from the Sun (at aphelion in its orbit) would get much larger in winter. Mars South pole is the one tilted away at Aphelion, so it should get bigger in winter.

Answer 5

i think the southern pole has a greater polar cap..... as you know mars is nearly the same as earth, so the phenomenons on earth is very similar to the phenomenons on mars...

Answer 6

Note to NeilB: Space explorartion has nothing to do with solving your earth problems. Ultimately only people can solve their own problems. Government can't do that.THERE IS NO "SPACE RACE".

Answer 7

This is an interesting question, and one that has made me curious for a long time.

Answer 8

To guy number one who replied: How dare you say that? i take it you are mistrusting of technology. but many people think that space exploration may be the key to earths survival.

And to the asker of the question, I don't get what you're asking.

Answer 9

That is interesting
