Question

You are studying an outcrop where the bottom layer is limestone and the layer directly on top of that is sandstone. Near the base of the sandstone are small, weathered pieces of limestone entirely contained within the sandstone.

Explain how these pieces of limestone came to be contained within the sandstone. In your answer, be sure to address the relative ages of the rocks.

Answer 1

Organic sedimentary rock

Step-by-step explanation:

• As sandstone is crate by the layering of the rocks in horizontal lines, while limestone is made of calcium deposits from the sources like the shells, bones, and corals.

• The create a solid color or even the formed by the precipitation of the calcium carbonated form the lakes or the ocean water example of coal, etc.

• As relative dating tells that older rocks are found at the bottom and relatively younger are found at the top. The sandstone is composed by quartz and feldspar is the most resistant material to erosion thus can be 416 million years old as to the limestone ie. 350 million years old.
