Also if you could can you answer those 2 questions-
2) What if the moon were much closer to earth? Will it change our ocean tide waves?
3) Which of earth's characteristic allow life to exist on the planet? How?

*I've had to edit this three times, so I expect a best answer.
1) The earth would be much hotter or colder depending upon which side you were on at the moment. Also gravity would be much less than what it is which might cause some elements in our atmosphere to escape as a result of centrifugal force. You have me at a loss for an exact answer to this question. I do not know exactly what would remain and what would escape, but this question might be moot as the atmosphere might be dramatically different from what we are used to (if oxygen for example was flung out into space, there would be no water). This in turn would make life on earth very difficult.
The poles would likely melt as a result of the higher median temperature on earth which would have a dramatic effect, especially is coupled with question number two.
All that aside, before the ice encroached upon the world as we know it the extreme temperatures caused by longer days and nights would create an inhospitable weather system where there would be substantially more water vapor in the air which would condense and then the dramatic differences in air temperature would cause unbearable winds and storms. A lot of plant and animal species would have evolved differently, and there is a good bet that mammals would be scarce and mankind would have never prospered as it has.
2) If the moon was closer the tidal bubble would be much larger, and if the moon was close enough to the earth every single night would be a battle against the advancing tides. Considering that the moon moves from east to west in the northern hemisphere you can assume that the east coast of America would be unlivable as the tide would come in for hundreds of miles (that is an estimate, but it is not inconceivable). Also the tide on the west coast would recede as the moon moved away (ie. the morning) and then come back in with the force of a tsunami.
