Illusion In Small Village, Alps

5. Below 1,000 metres are the lowlands. There a larger variety of plants are produced. Aside from plants, villages are also in the lowlands because the temperature is more bearable for both humans and animals.
The Alps is a classic example of what happens when a temperate area at lower altitude gives way to higher-elevation terrain. Elevations around the world which have cold climates similar to those found in polar areas have been called Alpine. A rise from sea level into the upper regions of the atmosphere causes the temperature to decrease (adiabatic lapse rate). The effect of mountain chains on prevailing winds is to carry warm air belonging to the lower region into an upper zone, where it expands in volume at the cost of a proportionate loss of heat, often accompanied by the precipitation in the form of snow or rain.
