Question

cars are powered by fossil fuels, which come from the remains of ancient living things that were buried and expose to high temperature and pressure from earth’s interior. which spheres are represented when fossil fuels form?
○ atmosphere and biosphere
○ biosphere and geosphere
○ cryosphere and atmosphere
○ geosphere and hydrosphere

Explanation:

To determine the spheres involved in fossil fuel formation:

1. Recall the definitions: The biosphere includes all living things (ancient living things here), and the geosphere includes Earth's interior (where burial, heat, and pressure occur).
2. Analyze options:

• "atmosphere and biosphere": Atmosphere isn't directly involved in fossil fuel formation from burial/geothermal processes. Eliminate.
• "biosphere and geosphere": Ancient living things (biosphere) are buried and exposed to Earth's interior (geosphere) heat/pressure. This fits.
• "cryosphere and atmosphere": Cryosphere (frozen water) and atmosphere are not key here. Eliminate.
• "geosphere and hydrosphere": Hydrosphere (water) isn't central to fossil fuel formation from organic remains and geothermal processes. Eliminate.

Answer:

B. biosphere and geosphere
