Document Summary
Q: if we remove the tilt of earth"s rotation axis, when would summer begin in the northern hemisphere: march, june, september, december, none of the above. A: e because without a tilt, the concentration of the sun"s rays is the same throughout, therefore the seasons would never change. Q: from earth, the stars in the big dipper constellation, appear in the shore of a spoon with a long handle. A: d because now the distance is being measured in light years which would make a difference rather than looking from planets where the distance is measured in au. Also, it is the first place where a difference in the shape would be noticed from rather than option e which is also correct but is not the first place to notice a difference from. A: the sun rises because earth is moving, to earth moves from darkness into light. It is an angle of 23. 5 degrees (earth"s tilt)
