The interior of south America has lower population than the coastal areas as ther is no proper water supplythere.
it doesn't. America's population is a medium density population that is predominantly in coastal regions
I believe most of the population of South America is located at or near the coastal regions (seacoast primarily) in larger cities and towns, some populations live along large rivers and in high mountains, but these are not the primary population concentrations of South America. I believe most tribal populations will contribute to the strong tendency of statistical migration to the coastal cities, and will not grow to large sizes in the interior regions, in the present era and foreseeable future.
North America has eight major land regions. They are (1) the Pacific Ranges and Lowlands, (2) the Western Plateaus, Basins, and Ranges, (3) the Rocky Mountains, (4) the Interior Plains, (5) the Canadian Shield, (6) the Appalachian Highlands, (7) the Coastal Lowlands, and (8) Central America and the Caribbean.
On the coastal regions.
Pacific Coast, Inter-mountain Region, Rocky Mountains, Interior Plains, Appalachian Mountains, Canadian Shield, Coastal Plains, Hawaiian Islands
Appalachian mountains
Coastal Plains, Coastal Range, Basin and Range, Great Plains, Canadian Shield, Interior Lowlands, Appalachian Mountains, and the Rocky Mountains region.
The answer is Coastal Range,Basin and Range, Rocky Mountains,Great Plains,Interior Lowlands,Appalachian Highlands,Coastal Plain,And Canadian Shield!
Physical regions, which are defined by natural features such as mountains, rivers, and climate. Political regions, which are defined by borders, governments, and administrative divisions.
interior highland areas
because we needed free and independent states
The Transantarctic Mountains divide Antarctica into eastern and western regions. These mountains stretch across the continent and act as a physical barrier, separating the coastal regions from the interior of Antarctica.
