Answer 2

Mineral oil is found under the land surface and also below the ocean floor. (Option c)

• Mineral oils are petroleum-based oils obtained by the purification of fossils like natural gas, crude oil, coal, etc.
• It forms by the decomposition of organic matter buried under the earth and sea bed millions of years ago.
• The bodies of organisms sink deep into the earth's surface and ocean floor, and there they get covered up in the sand, soil, and other sediments.
• Due to the high pressure and temperature under the ground, these dead remains get transformed into mineral oils.
• The mineral oils buried under the ocean floor are extracted through structures called mineral wells and other underground methods.
• Similarly, the mineral oils found under the land surface are closer to the surface and hence, they are extracted using surface mining methods.
