Question

which of the following are major influences on weather and climate?
i. the cycling of water in and out of the atmosphere
ii. the physical weathering of rocks and soil
iii. uneven heating of the earth by the sun’s energy
iv. global patterns of atmospheric movement
a. i, ii, and iii only
b. i, ii, and iv only.
c. i, iii, and iv only
d. ii, iii, and iv only

Explanation:

• Analyze each statement:
• I: The water cycle (cycling of water in/out of atmosphere) affects weather (e.g., precipitation) and climate.
• II: Physical weathering of rocks/soil is about breaking down rocks, not a major influence on weather/climate.
• III: Uneven heating by the Sun drives atmospheric circulation and weather systems, influencing climate.
• IV: Global atmospheric movement patterns (e.g., jet streams, wind belts) impact weather and climate.
• So, I, III, and IV are major influences.

Answer:

C. I, III, and IV only
