Question

Quizplus · Accepted Answer

Sand and gravel are used for construction purposes such as building roads and infrastructure. The demand for these resources is high, and they can be extracted relatively easily from the ocean floor. While gold and diamonds can also be found in the ocean, they are not as commonly recovered and require more complex and expensive extraction processes. Coal is primarily extracted from terrestrial sources and not as profitable to extract from the ocean.
