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 about Earth Science
Cool air flowing over the Earth's poles sinks and spreads over the surface of the planet. When air flows away from the poles, it goes to the west due to the Coriolis effect. When this air, known as the polar easterlies, meets prevailing winds at lower latitudes, the air's upward motion is reduced. This polar cooling and spreading occurs at 60 degrees of latitude on both poles.Full Answer >
One of the biggest disadvantages of hydroelectric energy is the major disturbance that damming a river causes to the surrounding people, animals and habitat. Another problem is that dams and hydroelectric power plants take many years to build and are incredibly expensive, although they do have only minimal costs once completed. Water must be abundant in the area, and maintenance standards must be strict.Full Answer >
Many forms of land-based life depend on fresh water, which comes from rain. Humans depend on rain to fill aquifers. Rain also plays a role in shaping the landscape and bringing nutrients to the ocean.Full Answer >
Mass wasting is a natural process, but it is influenced by roadway construction, removal of vegetation and the introduction of water to certain areas. Professor Stephen Nelson of Tulane University defines mass wasting as the down-slope movement of loose rock particles and soil.Full Answer >
