The correct option is Through the melting of glaciers. This answer is correct because it matches the approved learning objective to describe possible effects of global climate change, including rising sea levels in the subtopic Global climate change.
Explanation
The correct option is Through the melting of glaciers. Through the melting of glaciers is correct because it directly supports the approved learning objective to describe possible effects of global climate change, including rising sea levels. This belongs to the subtopic Global climate change within Carbon dioxide and methane as greenhouse gases, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Global climate change.
Common mistake
Misunderstanding Rising Sea Levels
Students often think that rising sea levels are solely caused by melting ice caps, ignoring thermal expansion of water.
Emphasize that both melting ice caps and the thermal expansion of water due to increased temperatures contribute to rising sea levels.
