What are the three major groups of rocks that natural aggregates come from?

Understand the Problem

The question is asking about the classification of natural aggregates based on their source rock types. We need to identify the three major groups of rocks that contribute to natural aggregates, which typically include igneous, sedimentary, and metamorphic rocks.

More Information

These are the three primary types of rocks based on their formation processes. Igneous rocks form from cooled molten material, sedimentary rocks from the accumulation and cementation of mineral and organic particles, and metamorphic rocks from existing rocks transformed by heat and pressure.
