I believe the accepted answer is that Earth is as round as a billiard ball, but not as smooth as one. The dips and peaks would be noticeable to the touch, but it would still be very round.
Actually you would barely notice them if at all. Let's argue that Mt. Everest (29,000 ft) was right next to the Mariana Trench (-35,000 ft). So a total change of 64,000 ft. That is roughly 12 miles. The earth's circumference is over 24,000 miles. Thus you are looking at a ratio of 0.0005

Lake Superior contains as much water as all the other Great Lakes combined, even throwing in two extra Lake Eries.

There is enough water in Lake Superior to flood all of North and South America to a depth of one foot.

Lake Superior contains 10% of the world's fresh water when measured by surface area.

However, Lake Baikal, in Russia, contains 22-23% of the world's fresh water by volume (it's insanely deep)-- more than all of the Great Lakes combined. :eek:

There are more molecules of water in a cup of water than cups of water in all the world's oceans. This means that some molecules in every cup of water you drink passed through the kidneys of Genghis Khan, Napoleon, Abe Lincoln or any other historical person of your choosing.

The Eiffel Tower gets taller in the summer.

Due to a process what boffins would call 'thermal expansion' the Paris landmark gains a few centimetres in the hot weather. The heat from the sun makes the metals used to stretch ever so slightly, but in the winter, it returns to its original height.

Vive la science!
