It is your job to group these four animals based on like features. First you group the animals by size: very large and not very large. Into the very large group you put the giraffe and elephant. You are left with the lion and alligator. What feature could you use to put these two animals into different groups?

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
