Answer: the mantle
Explanation:
The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the mantle is the thickest layer, while the crust is the thinnest layer.
Answer:
The answer is ... the mantel I think! But I may be wrong and it may be the outer core ... although that is just surrounding the inner core.
Explanation:
The mantle is the part right between the thin crust and the hot outer core. So, if you look at a "map" of the inside of earth - the mantle is probably the one that you're going to be stuck digging through the longest. I'm sorry I couldn't explain it right, but I tried ... don't be mad if this is wrong - I'm just taking my best guess!
Have a good day.
