Question

1. water is an important molecule to help sustain an ecosystem. what role does waters high specific heat play in maintaining global climate and the water cycle? (sc.912.l.18.12)

a. it promotes the freezing of water in the atmosphere.
b. it speeds up the evaporation and condensation processes.
c. it helps regulate temperature by absorbing or releasing heat.
d. it decreases cloud formation in the upper atmosphere during the summer.

Explanation:

To solve this, we analyze each option based on the concept of water's high specific heat:

• Option A: High specific heat is about heat absorption/release, not promoting freezing. Eliminate A.
• Option B: High specific heat doesn't speed up evaporation/condensation; it relates to heat regulation. Eliminate B.
• Option C: Water's high specific heat means it can absorb heat (e.g., in oceans during the day) or release heat (at night), which helps regulate temperature globally and in the water cycle. This matches the role of high specific heat.
• Option D: High specific heat has no direct link to decreasing cloud formation in summer. Eliminate D.

Answer:

C. It helps regulate temperature by absorbing or releasing heat.
