Question

1. climate change is most likely to cause which of the following?

a. decreased amount of water vapor in the atmosphere
b. decreased concentrations of heavy metals in a local pond
c. increased coastal flooding of low - lying areas
d. increased number and size of glaciers

1. proxy data regarding the amount of carbon dioxide in the atmosphere collected from ice cores, ancient sediments, and tree rings are all examples of which of the following?

a. unsupported evidence of past climate patterns
b. evidence of past climate patterns
c. non - scientific evidence of past climate patterns
d. pseudoscience that explains past climate patterns

1. there are sometimes anomalies in atmospheric co₂ and temperature data. how can these anomalies be used as evidence of natural climate change?

a. co₂ and temperature have a direct relationship and indicate climate extremes
b. co₂ and temperature have an indirect relationship and indicate climate extremes
c. co₂ and temperature cycles do not provide enough evidence
d. co₂ and temperature cycles are difficult to measure consistently

Explanation:

1. Climate change causes ice - sheets to melt and sea - levels to rise, leading to increased coastal flooding of low - lying areas. Water vapor in the atmosphere may increase, and heavy - metal concentrations in a local pond are not directly related to climate change.
2. Ice cores, ancient sediments, and tree rings are well - established scientific methods to study past climate patterns. They provide valuable evidence and are not unsupported, non - scientific, or pseudoscience.
3. CO₂ and temperature have a direct relationship. Anomalies in their data can indicate climate extremes and be used as evidence of natural climate change.

Answer:

1. d. increased coastal flooding of low - lying areas
2. b. evidence of past climate patterns
3. a. CO₂ and Temperature have a direct relationship and indicate climate extremes
