Which continents have coastline and mountain ranges that match up.

A. North America and South America.
B. Africa and South America.
C. Africa and North America.
D. Asia and Antarctica.

C. Africa and North America.

The correct answer is B. Africa and South America.

To determine which continents have coastlines and mountain ranges that match up, we need to examine the geographic features of each continent. Here's what we can gather:

A. North America and South America:
North America has a coastline along the Atlantic and Pacific Oceans, while South America has a coastline along the Atlantic Ocean and the Pacific Ocean. Mountain ranges such as the Rocky Mountains in North America and the Andes in South America run parallel to these coastlines. So, option A is a plausible match.

B. Africa and South America:
Africa has a coastline along the Atlantic Ocean and the Indian Ocean, while South America has a coastline along the Atlantic Ocean and the Pacific Ocean. Although both continents have mountain ranges, such as the Atlas Mountains in Africa and the Andes Mountains in South America, these mountain ranges do not align with their respective coastlines. Therefore, option B is not a match.

C. Africa and North America:
We've already discussed Africa in the previous option, which does not have matching coastlines and mountain ranges with South America. North America has coastlines along the Atlantic Ocean, the Pacific Ocean, and the Arctic Ocean, but it does not align with the coastlines of Africa. Additionally, the mountain ranges, such as the Rocky Mountains in North America, do not match with the mountain ranges in Africa. Hence, option C is not a match.

D. Asia and Antarctica:
Asia has coastlines along the Arctic Ocean, the Pacific Ocean, and the Indian Ocean. Antarctica, on the other hand, is mostly surrounded by the Southern Ocean and has limited coastal features. While both Asia and Antarctica have mountain ranges, such as the Himalayas in Asia and the Transantarctic Mountains in Antarctica, their coastlines and mountain ranges do not align. Therefore, option D is not a match.

In conclusion, the only option among the given choices that has coastlines and mountain ranges that match up is A. North America and South America.
