Which of the layers of the Earth has the following three characteristics? i. It is a solid outer layer. ii. It is between 3 and 30 miles thick. iii. It is separated into plates.

The crust is Earth’s solid outer layer. It is roughly 3 to 30 miles thick and is divided into tectonic plates. The mantle lies beneath the crust, while the outer and inner cores are much deeper, so the correct choice is the crust.
