PlaceThink about the characteristics of the area where you live. How does the land look? Is there a large body of water nearby? What is the climate like? Each place on the Earth is unique, with its own special characteristics. What kinds of geographic characteristics define the region where you live?Chapter Intro 1
Eyewitnesses to the 2004 tsunami in Indonesia saw animals running from the coastline soon before the waves hit. Later, rescue workers and investigators were surprised to find very few dead animals among the devastation. Scientists speculate that animals can hear, smell, and feel subtle environmental changes that serve as warnings to flee.Section 1

Between June and August 1993, an extraordinary amount of precipitation fell in the Midwestern United States. Meteorologists recorded a 200 to 350 percent increase from the normal rainfall. Floodwaters from the overflowing Mississippi and Missouri Rivers covered 400,000 square miles (1.04 million sq. km) and 15 million acres of farmland in nine states.Section 2

Tornadoes usually come one at a time, but now and then several come at once. What is now known as the Super Outbreak occurred in April 1974. In a 16-hour period, scientists counted 148 tornadoes in 13 Midwestern and Southern states. Five large tornadoes were on the ground at the same time.Section 3

Cattle ranchers in Oregon have a weed called “leafy spurge” that harms their ranchlands. Instead of spraying the weed with chemicals called herbicides, however, the ranchers have begun renting goats to eat the weeds. This natural alternative looks promising. The ranchers get rid of the weeds, no poisons are used, the goat owners have a new source of income, and the goats are happy.Section 4
