This layer of the earth lies between the mantle and the solid inner core. It is the only liquid layer, a sea of mostly iron and nickel about 1,400 miles (2,300 km) thick.
A lot of people want geologists, local councils are always in need of a geologist so that is an easy career. A geologist is a good career because people are looking for them and they become more and more important. I hope that helps
