No, the Earth's core is much larger than the Earth's crust.

Here's a breakdown:

* Crust: This is the outermost layer, like the skin of an apple. It's relatively thin, ranging from about 3 to 45 miles (5 to 70 kilometers) thick.

* Core: The core is the innermost layer, representing roughly 1/3 of the Earth's total mass. It's about 2,100 miles (3,400 kilometers) thick, with a solid inner core and a liquid outer core.

So, while the crust is what we live on and interact with directly, the core is vastly larger and makes up a significant portion of our planet.
