Which river forms part of the border between Costa Rica and Nicaragua?

The San Juan River is significant as it serves as a natural boundary between Costa Rica and Nicaragua. This river flows from Lake Nicaragua into the Caribbean Sea and marks a crucial geographical demarcation that has historical, political, and ecological importance for both countries. The river is not only a vital waterway but it has also been central to disputes and treaties between Costa Rica and Nicaragua over the years. In contrast, the Amazon River is located in South America and does not have any relevance to Central American borders. The Colorado River, primarily associated with the western United States, is also unrelated to the context of Costa Rica and Nicaragua. Finally, the Río Grande, which primarily refers to the river separating the United States and Mexico, has no bearing on the border between Costa Rica and Nicaragua. Thus, the San Juan River stands out as the sole relevant choice for this geographical question.
