Superposition

The law of superposition is one of the principles of geology scientists use to determine the relative ages of rock strata, or layers.This principle states that layers of rock are superimposed, or laid down one on top of another. The oldest rock strata will be on the bottom and the youngest at the top. Think about it like this: You have a magazine …

11.1: Relative Ages of Rocks

The youngest rock layers are at the top of the canyon, while the oldest are at the bottom, which is described by the law of superposition. Distinctive rock layers, such as the Kaibab Limestone, can be matched across the broad expanse of the canyon. We know these rock layers were once connected, which is described in the rule of lateral continuity.

Moreover, we adopt a channel attention module (CAM) to reweigh fea-ture maps in different channels to further improve the seman-tic segmentation results. 2.

Pavement Types – Pavement Interactive

Each of these pavement types distributes load over the subgrade in a different fashion. Rigid pavement, because of PCC's high elastic modulus (stiffness), tends to distribute the load over a relatively wide area of subgrade (see Figure 1). The concrete slab itself supplies most of a rigid pavement's structural capacity.
