Laws of relative dating geology chronological dating methods
Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
Once students begin to grasp "relative" dating, they can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history.
The relative ages of rocks are important for understanding Earth’s history.
New rock layers are always deposited on top of existing rock layers.
We know that we can relatively date layers of rock by knowing that the layers on bottom are older than the layers on top.The laws of stratigraphy are usually credited to a geologist from Denmark named Nicolas Steno. Superposition refers to the position of rock layers and their relative ages.Relative age means age in comparison with other rocks, either younger or older.Time factors of millions and billions of years is difficult even for adults to comprehend.However, "relative" dating or time can be an easy concept for students to learn.
