If Earth were an apple, its crust would be about as thick as the apple’s skin. That’s ridiculously thin—only 3 to 44 miles deep. We live on a cosmic fruit snack.
And get this: the crust under the oceans is way thinner (about 3–6 miles) than the crust under continents (up to 44 miles). So if you’re standing on dry land, you’re basically on the chunky part of the apple. Lucky you.
