北纬50度东经9度是什么山？这是一个地理坐标问题，涉及到地球上的一个特定位置。要回答这个问题，我们需要先了解这个坐标点位于哪个山脉。

通过查阅相关地理资料，我们得知这个坐标点位于阿尔卑斯山脉。阿尔卑斯山脉位于欧洲中南部，是一条巨大的山脉，跨越了多个国家，包括法国、意大利、瑞士、奥地利、德国等。这个坐标点位于阿尔卑斯山脉的某个山峰附近，具体是哪个山峰需要进一步查询资料。

为了确定这个坐标点所在的特定山脉，我们需要进一步研究阿尔卑斯山脉的分布和地理特点。阿尔卑斯山脉的主峰大多集中在瑞士、法国和奥地利等国家，其中瑞士境内的勃朗峰和马特洪峰是最著名的两个山峰。因此，我们可以推断这个坐标点可能位于这两个山峰或其周边地区。

总之，北纬50度东经9度所在的地理位置是阿尔卑斯山脉的某个山峰附近。具体是哪个山峰需要进一步查询资料或实地考察来确定。

What mountain is at latitude 50 degrees north and longitude 9 degrees east? This is a question about the location of a specific point on the earth. To answer this question, we need to identify which mountain this coordinate belongs to.

Through researching relevant geographical data, we learn that this coordinate is located in the Alps. The Alps, a vast mountain range in southern Europe, span multiple countries including France, Italy, Switzerland, Austria, and Germany. This coordinate is near one of the peaks of the Alps, but which peak exactly requires further investigation.

To determine the specific mountain at this coordinate, we need to further explore the distribution and geological characteristics of the Alps. The main peaks of the Alps are concentrated in Switzerland, France, and Austria, with Mount Blanc and Matterhorn being the most famous peaks in Switzerland. Therefore, we can infer that this coordinate may be located in the vicinity of these two peaks or other mountains in the Alps.

In summary, the location at latitude 50 degrees north and longitude 9 degrees east is near one of the peaks of the Alps mountain range. The specific peak requires further research or fieldwork to identify.
