Mountains arise

From the viewing platform of the Green Mountain Towers you have an excellent panoramic view over the surrounding area, which is characterized by elevations of various kinds. For example, hills, mountains and summits are terms that come into play and are not necessarily clearly demarcated. If you had a few million years, you could see mountains rise and landscapes change. Since most of the visitors do not have so much time and patience, there is a short summary here as an Earthcache.

A mountain is a topographic elevation whose counterpart is the valley. It should have a certain individuality, means not to be too close to other mountains, and also a significant minimum height above a pass. Normally, a mountain has a main summit and several secondary summits. From mountain climbers’ perspective a counter-rise of 30 meters is sufficient for defining another summit. If mountains belong together geologically and geographically, what is usually observed as a result of the continental drift, one speaks of a range or mountain chain, depending on the altitude of a high-altitude or lofty mountain chain or a low mountain range. Mountains arise mainly in two ways: as a gigantic "wrinkle" of the plate tectonics of the earth, when plates of the earth's crust shift against each other (-> see question 1),

or by volcanic origin by the accumulation and cooling of lava (-> see question 2). Mountains which are clearly demarcated to the surroundings are more common in this case. Volcanism itself, however, is a consequence of continental drift as well.

When you imagine the gigantic upheavals of mountain creation, it is no surprise that mountains can consist of a wide variety of rock types and strata. Analyzes can give geologists information about the formation and age of mountains. By the way, mountains can barely reach a height of more than 9 km because the base of a mountain on Earth would liquefy due to the enormous weight pressure of the rock strata above (lithostatic pressure).

A hill is also a terrain that rises above its surroundings. However, hills are smaller than mountains and they can be created in other ways, even man-made though they are usually called mound in that case (-> see question 4). A hill is not much longer than wide, otherwise it is called a ridge. You can often find hills on the edge of high mountains. A differentiation to a mountain via the altitude above sea level is not possible, as in the subjective assessment of the height the surrounding landscape is taken into account as well. By the way, in the amusing film "The Englishman Who Went Up a Hill But Came Down a Mountain" with Hugh Grant, in which a Welsh village struggles to recognize their local elevation as a mountain to be present on maps, the borderline between hill and mountain was 1,000 feet above sea level. In practice, mountains start somewhere between 100 and 300 meters difference in altitude to the surrounding landscape.

Back to Green Mountain Tower and the questions:

1. Name a mountain/ mountain chain of plate tectonic origin that can be seen (in good weather) from the Green Mountain Tower (you can refer to the informative boards).
2. Name a mountain of volcanic origin that can be seen (in good weather) from the Green Mountain Tower (again, you can refer to the informative boards).
3. Describe shortly in your own words how the appearance of mountains of plate tectonic origin and of volcanic origin differs. You also see mountains, which built up under glaciers. Are these mountains of volcanic or plate tectonic origin?
4. In addition to plate tectonics and volcanism, can you imagine other artificial or natural origins of hills or mounds? Please send me your ideas.
5. Optional, but highly appreciated: Take a picture of the landscape from the Green Mountain Tower, with you and/ or your GPS.

And now? Please send the answers to me BEFORE posting the log entry, preferably via message center and not by e-mail. A separate approval will not follow, you are allowed to log immediately after answering the questions. If something is wrong, I'll contact you. If no responses are sent to a log entry, I will delete it without further notice!

Es ist auch möglich, mir die Fragen auf Deutsch zu beantworten:

1. Benenne einen Berg/ ein Gebirge plattentektonischen Ursprungs, das (bei gutem Wetter) vom Green Mountain Tower aus zu sehen ist (Du kannst dabei die Infotafeln zur Hilfe nehmen).
   
2. Benenne einen Berg/ ein Gebirge vulkanischen Ursprungs, das (bei gutem Wetter) vom Green Mountain Tower aus zu sehen ist (Auch hier kannst Du die Infotafeln zur Hilfe nehmen).
   
3. Beschreibe mit eigenen Worten, wie sich das Erscheinungsbild von Bergen oder Gebirgen plattentektonischen Ursprungs und vulkanischen Ursprungs oftmals unterscheidet. Du siehst auch Berge, die unter Gletschern entstanden sind. Sind diese Berge vulkanischen oder plattentektonischen Ursprungs?
4. Kannst Du Dir neben Plattentektonik und Vulkanismus weitere künstliche oder natürliche Entstehungsarten von Hügeln vorstellen? Sende mir Deine Ideen.
5. Optional, aber sehr geschätzt: Mache ein Foto der Landschaft vom Green Mountain Tower aus, gerne mit Dir und/ oder Deinem GPS. 

Und jetzt? Bitte sende die Antworten VOR Verfassen des Logeintrags an mich, vorzugsweise per Message-Center und nicht per E-Mail. Eine gesonderte Freigabe erfolgt nicht, Ihr dürfte nach Beantwortung der Fragen sofort loggen. Falls etwas nicht stimmt, melde ich mich. Wenn zu einem Logeintrag keine Antworten gesendet werden, werde ich ihn ohne vorherige Ankündigung löschen.
