Crust (geology) the crust. The boundary between the crust and mantle is conventionally placed at the Mohorovičić discontinuity, a boundary defined by a contrast in seismic velocity. The crust of the Earth is of two distinctive types: Because both continental and oceanic crust are less dense than the mantle below, both types of crust "float" on the mantle. This is isostasy, and it's also one of the reasons continental crust is higher than oceanic: continental is less dense and so "floats" higher. As a result, water pools in above the oceanic crust, forming the oceans. The temperature of the crust increases with
Core-and-pod Core-and-pod Core-and-pod design is a network design that uses individual pods that hang off the core layer as atomic units. Within the pod, there may be only a single access layer or a “leaf and spine” network in the pod. The routed core layer serves as a fast and simple way to connect many generations of pods to each other. When the “leaf and spine” network is used within the pod, the core layer can be referred to as the “spine of spines,” since it is the thing that connects the “spines” of the pods. This design then resembles some
