Layers of Rocks Facts for Kids (All You Need to Know!)

Strata that are cut by a canyon later remain continuous on either side of the canyon.

1. Relative age dating

Help us work out the relative ages of the layers of sedimentary rocks.

Which layer of rock is the youngest?

Imagine cutting a slice of bread from a whole loaf.

What rock layer is the youngest?

Oldest F, E, D, C, B, H or A Youngest Fourth, we see that G, another igneous intrusion, cuts across A-H; it is therefore younger than all of these note that G is not displaced by A, the fault.

The three main rock layer sets in the Grand Canyon are grouped based on position and common composition and 1 Metamorphic basement rocks, 2 The Precambrian Grand Canyon Supergroup, and 3 Paleozoic strata.

Layers of Rocks Facts for Kids (All You Need to Know!)

When there is heavy rain or other strong weather, there can be spaces that happen between the different strata.

What is the principle of original horizontality examples? When a strata forms, it is usually a specific time or a specific place.

The river continues to be an agent of change, reshaping the canyon over time.

1. Relative age dating

What is law of lateral continuity? When this happens, geologists are able to figure out where the rocks are from and when they formed.

Grand Canyon Geology

Putting this all together, we can determine the relative ages of these rock layers and geological events: Oldest F, E, D, C, B, H or A , G, I Youngest Given the information available, we cannot resolve whether H is older than A or, vice versa.
