They say that the Earth's surface is smoother than that of a billiard ball, but still our planet's topography manages to range vastly in its highs and lows. Can you name some of the highest, lowest, and deepest points and things on the earth's surface? Though this quiz only deals with things on earth, there are plenty of interesting highs and lows beyond our planet too!
Answers may include both natural and artificial geographical points.
Unless otherwise stated, height/depth is given as altitude relative to sea level.
When talking about 'deep' things, their depths are maximum depths.
