They are used to determine the relative ages of rocks by stating that younger rocks lie above older rocks, and that rocks that cut through a layer are younger than the existing layer.

No, the law of crosscutting relationships can apply to any type of rock. It states that a geological feature must be younger than the rock it cuts across. This principle helps geologists determine the relative ages of rocks and geological events.
Relative dating depends on principles such as superposition, cross-cutting relationships, and fossil succession. These principles help geologists determine the relative ages of rocks by comparing their positions and relationships to each other.
The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.
A geologist would use the principle of superposition in the Grand Canyon by observing that in an undisturbed sequence of sedimentary rock layers, the youngest rocks are at the top, and the oldest rocks are at the bottom. By examining the layering of rocks in the canyon walls, they can determine the relative ages of the rocks based on their position within the sequence. This allows them to create a relative chronology of the geological history of the canyon.

Relative age can be determined using superposition and cross-cutting relationships. Absolute age can only be determined using radiometric dating methods, such as Rb-Sr.

No, sedimentary rocks are commonly used for relative age determination due to their layering and formation process. However, other types of rocks like volcanic rocks and metamorphic rocks can also be used to determine relative age based on principles of superposition, cross-cutting relationships, and faunal succession.
Crosscutting includes fractures (cracks in rocks), faults (fractures where movement has occurred), or masses of magma that cut across preexisting rocks before cooling. Any crosscutting feature must be younger than the rock or sediment it cuts across.
The law of superposition can determine the relative ages of rock layers or fossils in a sequence. It helps geologists understand the order in which geological events occurred, with the oldest layers at the bottom and the youngest at the top.
Relative dating involves comparing rock layers with others in a sequence to determine their ages. This process relies on the principle of superposition, where younger rocks are usually found on top of older rocks. By studying the relationships between different rock layers, scientists can establish the relative ages of the rocks.
The law of superposition states that in an undisturbed sequence of sedimentary rocks, the youngest rocks are on top and the oldest are at the bottom. By observing the layers of sedimentary rock, geologists can determine the relative ages of the rocks based on their position in the sequence. The principle helps establish a chronological order of events in Earth's history.
