    23.5 degrees

    93 million miles

    1 rotation per day. This is faster than the speed of sound at the equator.

    Atmosphere 78% nitrogen, 21% oxygen, 1% other

    If these were changed rapidly, we would likely die. Some of these attributes could be changed. For example, life thrived during the carboniferous age when the atmosphere had 3 times the carbon-dioxide it has today and the earth spun faster.

    About 23.4 degree angle

    About 93 to 97 millions from sun

    To make one complete 24 hours rotation about 1000 miles per hour (1600 km/hr).

    The atmosphere is a mixture of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth.

    And If there were variables to these. We would all die.

    The present composition of dry air is approximately 78.1% Nitrogen, 20.93% Oxygen, 0.94% argon and 0.04% carbon dioxide by volume with traces of several other gases including neon, xenon, krypton, methane, carbon monoxide. The proportion of carbon dioxide in the air increases slightly in the winter and decreases slightly in the summer, particularly in the northern hemisphere because of the large land masses with deciduous forests. This seasonal variation is superimposed on a steadily increasing concentration of carbon dioxide caused by coal and oil use. These figures are not permanent, there is no indication of any oxygen in the very early Earth and in earlier geological epochs the amount of oxygen was higher than it is now.

    The axial inclination to the plane of the orbit or ecliptic is about 23.5 degrees, this varies since the Earth wobbles slightly on its axis in several cycles, one of the shorter takes about 18 years.

    The orbit of the Earth is at present almost circular, on average we are 93 million miles from the sun but it varies by about 5% every year. This is the main reason that February has 28 or 29 days, since the southern summer is slightly shorter than the northern. We are closest to the Sun during the southern summer and the planet is moving slightly faster as a result. Some of this was worked out 2,300 years ago, so it's not new.

    This not permanent either, the orbit around the Sun is influenced slightly by the gravitational field of other planets, mostly Jupiter and Venus, our closest neighbour. The result of this is a series of ice ages. The motion of the Earth is not simple.

    Comma, does your keyboard have one?

    If some of these thing were different (and at one time they were) life would have evolved in a different way. At one time the atmosphere of the Earth was very different and there was life. The rotation of the Earth and the length of the day was different, and there was life.

    The Earth varies in its distance from the Sun as its orbit is not completely circular, and there is life.

    Axial tilt would make a difference in the seasons and perhaps the temperature and weather of the Earth, but, I believe that life would persevere.

    All of these can be Googled; but I guess 10 minutes takes up too much of your life.

    And all of these have changed over time, without life going extinct. For example, in January the earth is about 3 million miles closer to the sun than it is in July. Every year. As with everything, it depends on how much change you're talking about. A little bit of change is possible to live with. A whole lot of change is not.
