| The ______________________ extends from 66.5° N and 66.5° S latitude to the poles. | Polar zone |
| Climate zones that refers to the area located between the tropics and the polar zones are the______________________. | Temperature zones |
| Any structural or behavioral change that helps an organism survive in its particular environment is | Adaptation |
| a behavioral adaptation for winter survival in which an animal's activity is greatly reduced, its body temperature drops, and body processes slow down | Hibernation |
| Short periods of climate change caused by the tilt of Earth's axis as Earth revolves around the Sun | Seasons |
| climatic event that begins in the tropical Pacific Ocean; may occur when trade winds weaken or reverse, and can disrupt normal temperature and precipitation patterns around the world | El Nino |
