Imagine peeling an apple and calling that skin the crust. That’s the Earth’s crust compared to the planet. Under the oceans, it’s only about 3 to 6 miles thick—that’s thinner than your neighbor’s patience during a yard sale.
On land, it’s a bit chonkier, up to 25 miles thick. Still, if Earth were a basketball, you’d scrape the crust off with a fingernail. Talk about fragile! No pressure, literally.
