Sandstorms occurwhen winds strengthen to the point where they're able to lift grains of sand off the groundand blow them through the air. ... Moisture tends to hold particles to the ground, so dry conditions often lead to particles being picked up more easily by the wind. How long does ...
Most thunderstorms occur later in the day because in the evening, the ground is at its hottest, following an entire day of sun heating, which causes warm air to rise and meet the relatively cooler air up in the atmosphere, leading to instability. Also, daytime heating enhances the air’s ...
Do auroras occur only on Earth? Because auroras are caused by the interactions of solar winds and solar flares with the magnetic fields of a planet, you'd think they'd happen on other planets as well. What you need is: Solar flares and winds that provide the charged particles and energy...

Why and How sparkles occur in electric circuits ? Why are electric and magnetic fields perpendicular to each other? Why does lightning push electricity through air, but common batteries do not? How could everything come out of nothing?(Big Bang)?
Earthquakes can occur when those plates move against each other and create friction (摩擦力).Haiti is also overpopulated. Plus, many of its buildings are designed to resist hurricanes but not earthquakes. Those buildings can survive strong winds bat are easy to fail down when the ground shrike...
What causes strong winds? Why does orographic rainfall occur? How does vertical wind shear influence hurricanes? Why do sea breezes occur during the day? How do hurricanes cause erosion? What are the causes and effects of cyclones? Why does lightning tend to strike the tallest building nearby?
Human-ignited fires often occur in or near populated areas, where flammable structures and vegetation create even more hazardous conditions. Homes and the materials around them,such as wooden fences and porches,can burn quicklyand send burning embers airborne, further spreading the flames. ...
body temperature there. The drawback to this is if the body is unable to replenish the heat being lost, a drop in core body temperature occurs. And if core temperature drops below 95°F (the required temperature for keeping up normal body functions) frostbite and hypothermia could occur. ...
Why do polar easterlies occur? Cold air subsides at the pole creating the high pressure, forcing a southerly (northward in the southern hemisphere) outflow of air towards the equator. ... Since the winds originate in the east, they are then known as easterlies. ...
