Yes, it is much hotter than mars but it really depens at what time of the year, mars is a very cold planet it can go as low as -140*C on average and can only get up to as high as 27*C, meaning Earth is a hotter planet as it is closer to the sun

# Is Mars larger than the Earth?

No, Mars is much smaller than Earth, but both planets have similar amount of dry land.. Mars has a diameter of 6,792 kilometers = 4,220 miles at the equator. Earth has a diameter of 12,756.32 kilometers = 7,926 miles at the equator.. By size, one typically refers to volume. In this respect Earth i ( Full Answer )

# Why does Mars have a thinner atmosphere than Earth?

There are two factors. First, Mars has weaker gravity and so isless able to hold onto an atmosphere. Second and more importantly,Mars lacks a magnetic field to shield it from the solar wind, whichallowed much of its atmosphere to be stripped away.

It is due to the presence of water.. It shows that their is existence of life...we breathe oxygen who does know that the same thing is required for other gener or species. Because due to the presence of lot of tons of other gases available around the globe

# Why would you weigh more on earth than mars?

Because Mars is less massive than the earth therefore gravity is "weaker". You would weigh about one third of what you weigh on earth. Because it is smaller, thus containing less gravity.

# How much more sunlight on Mars than on Earth?

Mars gets LESS sunlight than Earth does, because of its greater distance from the Sun.

No, because it is only slightly larger than Earth's core, but is off an almost equal density.

# Why does Mars have seasons similar to those on earth?

Because its axle tilt is at 25 degrees just a fraction off from Earth's at 23.5 degrees. As it goes around the sun the southern and northern hemisphere's trade off summer from winter. But in Mar's case its orbit is slightly more elliptical than Earth's making this dynamic slightly more complex. In s ( Full Answer )

# Does the sun have more or less gravitational attraction on the earth than on the mars?

There is a stronger attraction between Earth and the sun than thereis between Mars and the sun because Earth is closer to the sun. Theactual force of the attraction is also greater because Earth hasmore mass than Mars.

# Why is Mars bigger than the Earth?

No it is smaller than earth. This has to do with the way how matter was distributed throughout our solar system at the time planets began to form.

# Does mars have more air than any other planet except earth?

No. If by air you mean atmosphere, the atmosphere of Mars is actually the second smallest of all the planets. Only Mercury has less atmosphere than Mars. If by air you mean an atmosphere that we can breath, no such atmosphere has been found on another planet.

# Does Mars has the same seasons you experience on earth?

Sort of. There isn't much water on Mars at all, and most of it is frozen in polar ice caps. That means there isn't really precipitation on Mars. There's also no life other than maybe some microorganisms, so you obviously wouldn't have leaves changing colors and falling off and the like. The main dif ( Full Answer )
