Geological Strata

“Why are different geological layers different from one another?”

If you dig into the Earth, you’ll notice that the crust is divided into different rock and sediment layers. This can seem very perplexing. How did this come to be? Well, each layer represents a different point in Earth’s history. Over time, what was on the surface became rock, and whatever properties they had influenced what rocks appear in the Geological Strata layers. Geological strata, or stratum for singular, imprint the Earth’s history and are crucial for understanding local lithological conditions.
