How would the climate on Earth be different if the landscape were no taller than 3000 ft above sea level,-mtns

Question

If the Earth had no mountains.

Answer 1

That's an interesting question. Probably more tornadoes on all continents. Cold snaps and extreme heat happening more often almost everywhere, I'd guess...though I can't be sure.

Take North America, the central part of the continent (from Canada's High Arctic to the Gulf of Mexico) is extremely flat allowing for cold dry air and warm moist air to collide causing the supercells that spawn all those deadly tornadoes in the region known as "Tornado Alley". The world would likely be more like that all over.

Answer 2

Weather conditions will almost be the same in all the places of earth lying in the same latitudes. The air flow will not be restricted by mountains and there will be thorough mixing of air resulting gradual change of weather if there is any at a particular place.Of course there will be sligtht variation depending upon the height(within 3000 ft) of the particular place .The weather prediction will be more easy.We may miss some hill stations which serve as summer resorts in tropical countries.People would have migrated to many places thousands of years back itself as mountains would not have been barriers.

Answer 3

Two examples....

Without the Alps the generally cool and dry summer climate in northern Europe would be changed by the influx of hot/moist Mediterranean air.

Without the Himalaya Mountain Range and Tibetan Plateau copious moisture from the southwest (summer) monsoon would reach well into the arid portions of western China and old Soviet "stan" nations.

Answer 4

It would just be non mountainous terrain, the low countries of holland belgium and luxembourg are one of the most prosperous countries in the world and are hundreds and hundreds of miles away from any mountains, it does not control the weather, just that they are a bit unfortunate when the tide comes in very high lol

Answer 5

to name a few, precipitation difference would be more evenly distributed, especially in the temperate and tropical zones. the temperate rainforest and temperate deserts would ceast to exist.

Answer 6

Fewer deserts. More even distribution of precipitation.
