Synopsis: Got a wave, a spiral, or a snowflake? There's a mathematical equation for that!
Excerpt: Our planet Earth is not a perfect sphere but rather an "oblate spheroid." This is because the Earth's rotation causes it to stretch out around the equator, flattening slightly at the poles like a short, fat tomato. A similar effect of rotation happens when a baker spins a ball of pizza dough into the air so it widens around the edges, eventually flattening into a disc.

Question: Choose the sentence in this excerpt that contains the figure of speech called a simile.
