Amazon Geography Teaser #5 – Answer

Question: Only a few thousand years ago, rain forests, like the Amazon, covered what percent of the Earth’s surface?

Answer Choices: A) 6% B) 11% C) 14% D) 21%

Correct Answer: C) 14%

Summary: Tropical rain forests, like the Amazon, get there name because of their geographical location in the Inter-Tropical Convergence Zone (ITCZ) between the Tropic of Cancer and the Tropic of Capricorn. The air within this zone rises and warms very rapidly, causing an abundance of rainfall. This significant amount of rainfall allows the many species of plants and animals to thrive in the Amazon. It is believed that only a few thousand years ago tropical rain forests once covered 14% of the Earth’s surface. However, massive exploitation of the forests with activities like logging, mining, agriculture and ranching have led to massive deforestation and the loss of many of the world’s tropical rain forests. Currently, tropical rain forests cover about 7% of the earth’s surface. See a map of the distribution of the earth’s rain forests HERE.
