GEOLOGY

Detailed explanation-1: -If you do, you might describe your age by saying “I’m older than my sister and younger than my brother.” In this way, you compare your age to others in your family. Your pile of dirty clothes demonstrates the first principle of relative age dating-superposition.

Detailed explanation-2: -Archaeologists use two kinds of dating methods: relative dating and absolute dating. In relative dating, we determine which things are older or younger based on their relationships. For example, we know from geology that soil layers near the surface of the ground are usually younger than those deeper down.

Detailed explanation-3: -Absolute dating techniques include radiocarbon dating of wood or bones, potassium-argon dating, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics.

Detailed explanation-4: -Before geologists can correlate the ages of rocks from different areas, they must first figure out the ages of rocks at a single location. Within a single locality, geologists are able to determine which rock units are the oldest and which are youngest. This type of analysis is called relative age dating.

Detailed explanation-5: -Relative Dating. Uniformitarianism. The principle of original horizontality. The principle of lateral continuity. The principle of superposition. The principle of cross-cutting relationships. The principle of inclusions. The principle of baked contacts.
