Exploring the World of Quarries

What is the purpose of the quarry shown in the image and what type of rock is it extracting?

A. To extract sedimentary limestone
B. To extract igneous rock
C. To extract metamorphic rock

Final answer:

The purpose of the quarry is to extract sedimentary limestone for construction, which is then crushed into gravel for use in building roads and structures.

Explanation:

The purpose of the quarry shown in the image is to extract sedimentary limestone rock for use in construction. The quarry operates by cutting through layers of rock labeled W through Z. Large diesel-powered machinery and trucks are involved in the removal and transportation of the rock and gravel material to construction sites. This limestone is primarily composed of calcite and aragonite and includes skeletal fragments of marine organisms.

Once extracted, limestone can be crushed to make gravel of various sizes, which are then utilized in the building of structures and roads. The strength and durability of stone, such as limestone, have allowed it to be a key material in construction throughout history, remaining as one of the few surviving components of ancient civilizations in the form of stone sculptures.
