Question

1. scientists predict that rising sea levels from global warming may have an effect on the coastlines. what is the best argument to support this prediction?

a. acid - rain is causing temperatures to decrease and more glaciers to form, resulting in deposition of new land along the shoreline.
b. acid - rain is causing temperatures to increase which is melting glaciers and ice caps, resulting in deposition of new land along the shoreline.
c. burning fossil fuels is causing temperatures to decrease and more glaciers to form, resulting in erosion of land along the shoreline.
d. burning fossil fuels is causing temperatures to increase which is melting glaciers and ice caps, resulting in erosion of land along the shoreline.

Explanation:

To determine the best argument, we analyze the relationship between global warming, its causes (burning fossil fuels), effects (temperature increase, melting glaciers/ice caps), and the impact on shorelines. Burning fossil fuels increases greenhouse gases, raising temperatures. This melts glaciers and ice caps, increasing sea levels. Higher sea levels erode shorelines. Option D correctly links burning fossil fuels (cause of warming), temperature increase, melting ice, and resulting shoreline erosion. Options A and C incorrectly state temperature decrease, and B mentions acid - rain (not related to sea - level rise from melting ice) and deposition (opposite of erosion from rising seas).

Answer:

D. Burning fossil fuels is causing temperatures to increase which is melting glaciers and ice caps, resulting in erosion of land along the shoreline.
