Cars are powered by fossil fuels, which come from the remains of ancient living things that were buried and exposed to high temperature and pressure from Earth’s interior.

Question

Which spheres are represented when fossil fuels form?

atmosphere and biosphere
biosphere and geosphere
cryosphere and atmosphere
geosphere and hydrosphere

Answer 1

The correct answer is biosphere and geosphere.

The biosphere represents the living organisms, while the geosphere refers to the Earth’s solid parts, including the crust and the processes that occur beneath it. Fossil fuels form from the remains of ancient living organisms (biosphere) that have been buried and subjected to heat and pressure over millions of years in the Earth's crust (geosphere).
