The <em>Acadians</em> ... who came from the French-speaking <em>Acadiana</em> region in
Canada, navigated all the way down the east coast of the US, around Florida,
and then for some mysterious and eternally inexplicable reason decided to settle
on the Gulf Coast of Louisiana, generally between Nawlins and Lak Charlie ...
soon became addressed by the locals there as " <em>Cajuns</em> ".
The answer is; Wind
They drive atmospheric circulation. The sun does not heat the earth evenly. The parts that are heated up more form the low-pressure systems where air masses move in from high-pressure systems to form winds. These air masses are also deflected by Coriolis effect caused by earth’s rotation.
Contour lines determine the steepness of the land by how close they are together. Generally, contour lines rise to a particular scale (e.g. a line for every ten metres), therefore, if the contour lines are closer together then the height of that particular area has risen more steeply than if the contour lines are further apart where the steepness has increased more gradually.
Yes yes yes yes yes yes yes.
