Question

1. which of the following statements best sums up what unit 3 was about? (1 point)

how conditions of the atmosphere create weather patterns
how the impacts of using alternative energy sources can benefit the environment
how humans rely on the ocean in different ways
how and why climate has been changing in connection to human activities

Explanation:

To solve this, we analyze each option:

• Option 1: Focuses on atmospheric conditions and weather patterns, which is more about short - term weather rather than a unit - level summary (likely not the best).
• Option 2: Talks about alternative energy and environmental benefits, which is a narrow topic about energy, not a broad unit summary.
• Option 3: Centers on human reliance on the ocean, which is a specific topic about ocean - human interaction, not a general unit - wide theme.
• Option 4: Addresses climate change in relation to human activities. This is a comprehensive topic that can be a central theme of a unit, as climate change and its connection to human actions is a major, broad - ranging subject.

Answer:

D. How and why climate has been changing in connection to human activities
