South America accounts for ___ of the Earth's total land area ?
Show answer Hide answer
Answer: B. 11.8%
Explanation
South America comprises approximately eleven point eight percent of the total land area of the Earth. Geographical measurements confirm that the South American continent covers roughly seventeen million eight hundred thousand square kilometers. Cartographic data verifies that eleven point eight percent accurately reflects South America's share of global land. Earth's total land surface is divided among seven distinct continents possessing varying geographic sizes and ecosystems. South America is the fourth-largest continent by land area, featuring diverse terrain including the Andes and Amazon. Continental land area percentages are calculated using precise satellite mapping and geographical survey technologies.
Alternative percentage figures such as fifteen point eight percent significantly overestimate the total land area of South America. Lower estimates like ten point eight percent fail to match official geographical surveys of continental landmass ratios. Other numerical options represent incorrect statistical figures derived from inaccurate continental boundary calculations.
