Why is Mars to cold to support life, and why is Venus to hot to support life?

Just some science homework.

Thanks for the answers. I knew Earth was just right because of the greenhouse effect and its positioning from the sun, but I was not sure about venus or mars. Thanks for the answers.

Venus is too close to the sun, and Mars is too far away from the sun.

Venus is too close to the sun, and Mars is too far away from the sun.

Because of their distance from the Sun. Venus is too close to the Sun (too hot), Mars is too far from the Sun (too cold), but Earth is just right.

[yeah]

because mars is father from the sun and venus is closer to the sun
