natural disasture
| Term | Definition |
|---|---|
| wind | the perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction. |
| air pressure | The definition of air pressure is the force exerted onto a surface by the weight of the air. |
| high pressure system | A high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds. |
| low pressure system | A low pressure system is a whirling mass of warm, moist air that generally brings stormy weather with strong winds. |
| westeriles | a wind blowing from the west.the belt of prevailing westerly winds in the mid-latitudes of the northern and southern hemispheres. |
| easterlies | a wind blowing from the east. |
| trade wind | a wind blowing steadily toward the equator from the northeast in the northern hemisphere or the southeast in the southern hemisphere |
| global wind | Global wind patterns: Winds are named by the direction from which they blow. The globe is encircled by six major wind belts, three in each hemisphere. |
| doldrums | an equatorial region of the Atlantic Ocean with calms, sudden storms, and light unpredictable winds. |
| sea breeze | a breeze blowing toward the land from the sea, especially during the day owing to the relative warmth of the land. |
| land breeze | a breeze blowing toward the sea from the land, especially at night, owing to the relative warmth of the sea. |
| jet stream | a narrow, variable band of very strong, predominantly westerly air currents encircling the globe several miles above the earth. |
| energy | the strength and vitality required for sustained physical or mental activity. |
| Coriolis effect | an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation. |
| hurrican | a storm with a violent wind, in particular a tropical cyclone in the Caribbean. |
| tornado | a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud |
| vortex | a mass of whirling fluid or air, especially a whirlpool or whirlwind. |
| focus | the center of interest or activity. |
| tectonic plates | Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere. |
| normal fault | A normal fault occurs when the crust is extended. Alternatively such a fault can be called an extensional fault. |
| reverse fault | If the hanging wall rises relative to the footwall, you have a reverse fault. Reverse faults occur in areas undergoing compression (squishing). |
| strike-slip fault | a fault in which rock strata are displaced mainly in a horizontal direction, parallel to the line of the fault. |
| p waves | P-waves are a type of elastic wave, and are one of the two main types of elastic body waves, called seismic waves in seismology, |
| s waves | In seismology, S-waves, secondary waves, or shear waves (sometimes called an elastic S-wave) are a type of elastic wave, and are one of the two main types of elastic body waves |
| Richter scales | a numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations. |
| epicenter | he point on the earth's surface vertically above the focus of an earthquake. |
