What do the law of superposition and the law of inclusion have in common? (1 point)
• Both laws describe the relative ages of rocks.
• Both laws give the exact ages of rocks.
• Both laws are about the ages of intruding rocks.
• Both laws are about matching fossils in different areas.
Both laws describe the relative ages of rocks.
The correct answer is:
• Both laws describe the relative ages of rocks.
The correct answer is: "Both laws describe the relative ages of rocks." (1 point)
The law of superposition and the law of inclusion both deal with determining the relative ages of rocks.
Explanation:
1. Law of superposition: This geological principle states that in an undisturbed sequence of rock layers, the youngest rocks are on top, while the oldest rocks are at the bottom. By observing the order in which rock layers are arranged, geologists can infer the relative ages of the rocks.
2. Law of inclusion: This law states that if one rock body contains fragments of another rock body, the rock fragments must be older than the surrounding rock. Inclusions are pieces of one rock that have been incorporated into another, typically through sedimentary processes. By studying the relationship between inclusions and the rock layers they are found in, geologists can determine the relative ages of the rocks.
Both laws focus on determining the relative ages of rocks rather than providing exact numerical ages. They provide valuable tools for understanding the chronological order of rock formations and the processes that have shaped Earth's geological history.
