○ b hydrosphere
○ c biosphere
○ d lithosphere

question 11 (2 points)
when a heavy sea plates pull apart, the process of ______ creates underwater trenches, volcanoes and mountains.

○ a faulting

Explanation:

Question 10

To solve this, we recall Earth's spheres: atmosphere (air), hydrosphere (water), biosphere (life), lithosphere (rocky outer layer). The question is about all Earth's water, so hydrosphere matches.

We analyze plate tectonics: faulting (fractures), subduction (one plate under another), spreading (plates pull apart, creating features like trenches, volcanoes), accretion (material accumulation). When plates pull apart, spreading occurs.

Answer:

b. hydrosphere
