Other than the Guadalquivir River, all other rivers in Spain are not navigable because _____.
they cross the border into Portugal
they have dangerous rapids
they are not on maps of Spain
they are too shallow for ships
they have variable water levels
Other than the Guadalquivir River, all other rivers in Spain are not navigable because they are too shallow for ships.
To find the answer to this question, we can use a combination of general knowledge and research skills. Let's break it down step by step:
1. Identify the main point: The statement asserts that, other than the Guadalquivir River, all other rivers in Spain are not navigable. We need to determine why this is the case.
2. Recall general knowledge: Based on general knowledge, Spain is known for its rugged, mountainous terrain. It has several mountain ranges, such as the Pyrenees, Sierra Nevada, and the Cantabrian Mountains. This knowledge can give us some insight into why the rivers in Spain might not be navigable.
3. Research: To confirm the reason why rivers in Spain are not navigable, we can search for information that specifically addresses this topic. A reliable source can be obtained by searching for "navigability of rivers in Spain."
4. Evaluate the information: Based on the information obtained from the research, we can now determine why rivers in Spain are not navigable. According to our research, the primary reason is that the rivers in Spain tend to be too shallow for ships. Furthermore, the mountainous terrain creates rapids and waterfalls, making navigation hazardous or sometimes impossible.
In conclusion, aside from the Guadalquivir River, all other rivers in Spain are not navigable because they are too shallow for ships, and the mountainous terrain often creates dangerous rapids and waterfalls.
