Is a surface wave a whole different type of wave, or is it a transverse wave? Explain. What is the difference between body and surface waves? How are P waves and S waves alike? How are standing waves produced? What breaks surface waves? How are longitudinal waves formed? How are seconda...
Upward air currents, usually either called convective currents or thermals, are typically localized parcels of air that rise from the surface. They are important in the formation of clouds and thunderstorms because rising air cools adiabatically, often to its dewpoint, at which point it is forced ...
If winds affect only the upper 100 meters (328 feet) of water, how are deeper ocean currents formed? Find out on the next page. Current Catastrophes Before much was known about ocean currents, sailors would stop their boats for the night only to wake up extremely confused when they found ...
When an arc jumps across the contacts, it can melt a small section of the contact surface. If the contacts are still closed when the molten section re-solidifies, the contacts may weld together. The spring force in the reeds is often not sufficient to mechanically break the weld after ...
It's a dark, clear, moonless night. You look up into the sky. You see thousands ofstarsarranged in patterns or constellations. The light from these stars has traveled great distances to reachEarth. But what are stars? How far away are they? Are they all the same? Are there otherplanets...
Ocean and wind currents are formed by a process known as convection. Both convection and pressure affect the flow of water and air. As air and water currents move from one area to another, they affect the general climate of the area they are moving into. ...
The aluminum tubes are hinged so that the glider can be easily assembled and folded up for transport. Basically, the pilot unpacks the glider, assembles the control bar, unfolds the crossbar, stretches the sail out, rigs the various wires and inserts the battens. Tandem hang gliding. The ...

Describe and explain how hurricanes are formed and the dynamics that cause them to strengthen or weaken. Why are thick wires rather than thin wires usually used to carry large currents? Explain why the temperature at the equator is always hot and the temperature at the poles is always cold, ...
Monsoons are formed due to the temperature differences between ocean and land which changes seasonally. During summer, the air in the land is warmer... Learn more about this topic: Monsoon Winds | Definition & Causes from Chapter 9/ Lesson 8 ...
