If you get caught on foot in a sandstorm, put on a pair of goggles or sunglasses if available. It is impossible to navigate, so mark the direction in which you are traveling and lie down, preferably behind a rock or some other obstruction. Wrap a piece of cloth over your mouth and face, or pull your shirt over your head. Drivers should pull off the road.Know More
If water is available, moisten the shirt or cloth you use to cover your face. It is important to protect your eyes, nose and mouth from the sand. Sand in the respiratory system causes silicosis which leads to asphyxiation or possibly lung cancer. Untreated keratoconjunctivitis sicca, or dry eyes, from sand storms can cause blindness. If you are caught in an area where no shelter is available, Lie down opposite the direction of the wind with your stomach and face towards the ground.
Driving is hazardous in a dust storm, so pull your vehicle as far off the road as possible. Turn off the lights, set the emergency brake, and take your foot off the brake pedal. If you leave your lights on, drivers in cars behind you may think you are still driving and collide with your car. If you cannot pull off the road, leave your lights on, slow down, honk your horn occasionally, use the center line for navigation, and look for a place to pull over.Learn More
Geysers occur when underground water deposits are heated by geothermal energy and build up pressure. When underground magma flows heat the reservoir above the boiling point, water is forced to the surface. Once the first splashes of water begin to erupt from the geyser, the entire body of water boils as the pressure decreases. This produces a massive spume of water and steam, emptying the reservoir.Full Answer >

Wind is caused by a pressure difference in the atmosphere, resulting in air moving from an area of high pressure to low pressure. The air movement is felt as wind. Pressure differences are caused by areas in the atmosphere with either rising or sinking air.Full Answer >
