1-LAYERS OF THE EARTH []

2- FACTS ABOUT EARTHQUAKES :
 * The **largest recorded earthquake in the world** was a magnitude 9.5 (Mw) in Chile on May 22, 1960.
 * The **earliest reported earthquake in California** was felt in 1769 by the exploring expedition of Gaspar de Portola while the group was camping about 48 kilometers (30 miles) southeast of Los Angeles.
 * The **largest recorded earthquake in the United States** was a magnitude 9.2 that struck Prince William Sound, Alaska on Good Friday, March 28, 1964 UTC


 * **Moonquakes** (“earthquakes” on the moon) do occur, but they happen less frequently and have smaller magnitudes than earthquakes on the Earth. It appears they are related to the tidal stresses associated with the varying distance between the Earth and Moon. They also occur at great depth, about halfway between the surface and the center of the moon.
 * Although both are sea waves, a **tsunami and a tidal wave** are two different unrelated phenomenona. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth. A tsunami is a sea wave caused by an underwater earthquake or landslide (usually triggered by an earthquake) displacing the ocean water.

3- NATURAL DISASTERS :Disasters come in many shapes and sizes. Most are related to the weather. Some are predictable -- like a hurricane. Some, like an earthquake, surprise us. It’s good for us to know about the different kinds of disasters so we can be prepared! Although disasters themselves aren’t fun.

4-SURVIVAL KIT : 1-first aid ; bandages,pain reliver....2- clothing and bedding : change of clothes,a pair of shoes,a rain gear,sleeping bag.3-water.4-food that can stay long time without refrigerator.5- tools and supplies : flashlight and batteries,radio,cellphone.
 * 1- Volcanoes : more than 80 percent of the earth's surface is volcanic in origin. The sea floor and some mountains were formed by countless volcanic eruptions. Gaseous emissions from volcano formed the earth's atmosphere.There are more than 500 active volcanoes in the world. More than half of these volcanoes are part of
 * the "Ring of Fire," a region that encircles the Pacific Ocean.
 * 2- Hurricanes : are more than 500 active volcanoes in the world. More than half of these volcanoes are part of the "Ring of Fire," a region that encircles the Pacific Ocean.
 * Hurricanes rotate in a counter-clockwise direction around an "eye." Hurricanes have winds at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge. Storm surges are very dangerous and a major reason why you MUST stay away from the ocean during a hurricane warning or hurricane.
