The French league had different values at different times: 10 000, 12 000, 13 200 and 14 400 French feet, about 3.25 km to about 4.68 km. It was used for a while together with the metric system but it is not used now. The nautical league was three nautical miles.
Why does precipitation fall mainly on the windward side of a mountain? When humid winds blow from the oceans toward mountains they must rise up to pass over the mountains. The rising warm air cools when it rises and its water vapor condenses, forming clouds rain or snow falls on the windward side of the mountain. microclimate Climate within a small area that differs significantly from the climate of the surrounding area
Retired in 2005, breeding Araucana chickens. Orographic rainfall is when a parcel of air containing water vapor gets to a mountain, it is then forced upwards (the mountain blocking its way). As the parcel of air is forced upwards, it expands (adiabatic expansion) and also cools.rographic effect occurs when an air mass approaches a mountain range and is rapidly forced upward, causing any moisture to cool and create precipitation in the form of rain o â¦ r snow.  Quick answer: Rapidly rising air forced up by mountains creates rain or snow.
