词汇精练——give way to

Beyond a depth of around 2,900 kilometers, a great change takes place and the mantle gives way to the core.< Some seismic waves cannot pass through the core and others are bent by it. From this and other evidence, geologists conclude that the outer core is probably liquid, with a solid center. It is almost certainly made of iron, mixed with smaller amount of other elements such as nickel.
