If it s just 500 meters, it s not a hill

Hills are generally above 200 meters above sea level, below 500 meters, and the relative height is generally not more than 200 meters.

And it's important to note that yes, that's about that, not that it's not a hill if it's above 500 meters, and besides, there's no one who says 501 meters is not a hill.

And then you look at the relative altitude, and if somewhere is 10 meters above sea level and there's a 500-meter hill, it's not or it can't be called a hill.

Geographically or in this world, it is rare to encounter absolute things, such as the first line of the Huai River in the Qinling Mountains, if you investigate the problem of freezing, or the problem of 0 degrees in winter, then ask whether the Huai River is frozen or not, then it is not impossible to say, right?

The exam doesn't ask such extreme questions, just have an approximate value.

If we ** say it, we can just judge it at the first time, and I believe that LZ doesn't feel very interested in such an extreme problem.

Not necessarily... A 50-metre difference in height may be called a hill in a relatively flat area, and a hill may be called a hill in a proximity area with a height difference of more than 100 to 200 metres.

Less than 500 meters is necessarily hilly...

It is equivalent to a specific analysis according to the specific situation of the terrain.

Less than it must be.

500 meters is mountainous. In general, the height of hills is between 200 and 500 meters, while the height of mountains is more than 500 meters, but this is not the only criterion. For the classification of topography and landform, it is necessary to consider multiple factors, such as the geological structure of the mountain, the formation process, the steepness, the topography, etc., and the combined effect of these factors determines the topography of an area.

In geography, a hill is defined as an undulating terrain with a lower height than a mountainous area. They are usually higher than the surrounding flat areas, but lower than the nearby high mountains. In addition, the hills have a slower slope than cavity rocks, with flat tops and striped shapes, which are formed by erosion.

Unlike hills, mountains are higher in height and have steeper slopes, making it easy to identify ridges and peaks with continuous heights.

For a height of 500 meters, it is located at the junction of hills and mountains, therefore, depending on the specific topographic conditions, it may be classified as a mountain or hilly. The criteria for classifying heights may also vary from region to region. In addition, it is important to note that the topography of the earth is constantly evolving and changing, and over time, the original hills may also be eroded into mountains, or conversely, become hills due to the uplift of the earth's crust.

In short, the classification of topography does not depend solely on height, but requires a comprehensive consideration of multiple factors, such as gravity, crustal movement, erosion, and so on. For a height of 500 meters, it may be classified as a mountain or hilly, or a topographic landform located at the junction of mountains and hills. <>

Reading the map, it can be concluded that the altitude of point A is 600 meters, and the altitude of Gaokai in Jiacun is 200-100 meters, so it is determined that the topographic type of Qijiahu area is mountainous, and the relative altitude of point A and Jiacun is less than 500 meters
