it is considered a tropical storm and it gets a name from a list put out by the World Meteorological Organization. Once those sustained winds reach 74 to 95 mph (119 to 153 km/h), that storm becomes a Category 1
you can sometimes pass the shock on to someone else.) The opposite of a conductor is an insulator, which impedes the flow of electrons from one material to another. Rubber is a great insulator, which is why it’s safe to be inside a car (with rubber tires) during a lightning storm. ...
The movement of plasma(等离子体) on the sun's surface can change the sun's magnetic field (磁场). When this happens, a "solar storm"can break out. These storms can cause powerful bursts of electromagnetic(电磁的)energy that can affect us here on Earth by damaging power grids(电网) and...
We're currently experiencingsolar maximum, the peak of the sun's approximately 11-year cycle of magnetic activity. This means the sun is producing more sunspots,solar flaresandcoronal mass ejections(CMEs) — massive bursts of solar material that can supercharge auroras on Earth. During this per...
If this solar cycle produces a flare like the 1859 Carrington Event, we may face trillions in damages and year-long blackouts, experts say.
What is a Tornado? A tornado is a rapidly rotating column of air extending from a thunderstorm to the surface of the Earth. This mobile, funnel-shaped cloud typically advances beneath a large storm system. Tornadoes are visible because, nearly all the time they ave a condensation funnel made...
Protecting the environment,is everybodys business." Every time I go in the busy streets,always see some throw on the ground of dazzling things:the packing bag of brightly colored,the crush cigarette end,didnt chew clean apple and roll into a mass of waste paper.If everyone so dont speak hyg...
Based on our review we conclude that deltas should be considered complex socio-ecological-cum-technical systems and that transformations are needed to achieve sustainability in deltas. The interdependency between societies, their natural environment and technological intervention is evident in deltas, sinc...
Venus is the closest planet to Earth under most circumstances. Venus orbits the sun at a distance of about 67 million miles, while the Earth orbits at about 93 million miles. From basic geometry, then, when the two planets are at their closest, which occurs when Venus is right between the...
Summer is here. It's time to put on your mouse ears and take the family to Disneyland or Walt Disney World. If you've booked a summer trip to a Disney park, you need to figure out what to pack for your vacation to the "happiest place on Earth." Having been to the happiest plac...
