Question

1. which of the following is the best reason climate change has occurred over the course of earth’s long history? (1 pt) (1 point) a. ocean acidification b. a natural pattern of temperature fluctuation on earth c. agricultural run off d. burning of fossil fuels 8. which of the following is not a human impact on earth’s oceans (1 pt) (1 point) a. increased food production b. industrial revolution c. use of household products d. construction of dams e. severe weather events

Explanation:

For question 7: Ocean acidification, agricultural runoff, and fossil fuel burning are human-driven or modern climate change impacts. Earth has a natural, long-term pattern of temperature shifts (like ice ages and warm periods) that predate human activity, making this the best reason climate change is a long-term Earth pattern.
For question 8: The Industrial Revolution, increased food production, household product use, and dam construction are all human activities that directly affect oceans. Severe weather events are a result of climate and environmental changes, not a human-caused impact on oceans.

Answer:

1. B. a natural pattern of temperature fluctuation on Earth
2. E. severe weather events
