How do hurricanes cause erosion? Why are waterspouts short-lived compared to tornadoes? How did Dr. Fujita develop his scale for measuring tornadoes? How do air currents act around lightning? What damage can a tornado cause? Why does high wind shear destroy hurricanes?
These eruptions filled the air with carbon dioxide and sulfur, changing the climate and damaging plant and animal life. The changing face of the planet may have also played a role. As the continents moved, ocean currents would have changed the weather patterns in different parts of the world....
Depending on the speed and direction of the wind and the weight of the local sand, dunes will develop into a different shapes and sizes. Stronger winds tend to make taller dunes; gentler winds tend to spread them out. If the direction of the wind generally is the same over the years, ...
Why does air rise at the equator? How do clouds and precipitation in the atmosphere develop? Please describe the structure of a hurricane, and how they work. Include a discussion of how energy is transferred, from the warm ocean water, up to the sky. ...
Electrical engineers frequently specialize in a particular type of technology and develop expertise in that area, experts say. "Depending on a specific individual's field of practice, one could find themselves designing the latest computer chip, designing electronics systems that must...
The first hardware challenge is to develop CDR solutions that are durable, meaning they sequester captured carbon in a way that won’t leak back into the atmosphere over the next few thousand years. The best way to do this is to remove CO2 from the “fast carbon cycle,” which in...
The specimen usually has to be specially prepared and held inside a vacuum chamber from which the air has been pumped out (because electrons do not travel very far in air). The lenses are replaced by a series of coil-shaped electromagnets through which the electron beam travels. In an ord...
Once the fleas are fully developed they’ll jump onto their new host. They’re stimulated by air currents, carbon dioxide, touch, and light. If you suspect you have fleas you can wear white socks around the areas your dog hangs out. The vibrations and pressure walking creates should trigger...
How are air currents affected by the Earth's spin? Why do magnets lose their magnetism when heated? How badly has the shifting of magnetic poles affected our magnetosphere? How do honey bees use magnetism? How do flowers help plants reproduce?
But how do we get the sails and their spacecraft into space? Let's take a look. You want holes in the sail? Les Johnson, of Marshall Space Flight Center, holds a rigid, lightweight carbon fiber material that gave many solar-sail-scientists pause for thought. This fiber was a departure...
