Hydrologic Cycle |
The Water Cycle |
|

Wind |
The horizontal movement of air from an area of HIGH pressure TO an area of LOW pressure |
|
|
Wind Chill Factor |
A measure of "cooling" combining temperature and wind speed. |
|
|
Global Winds |
Winds that blow steadily from specific directions over long distances (like Easterlies, and Westerlies). |
|
|
Conduction |
The DIRECT TRANSFER of THERMAL ENERGY from one substance to another substance that is TOUCHING |
|
|
Convection |

|
|
Coriolis Effect |
The effect of the Earth's ROTATION on the DIRECTION of WINDS and CURRENTS |
|
|
Evaporation |
The process by which WATER molecules in LIQUID WATER escape into the AIR as WATER VAPOR. Usually due to HEATING. |
|
|
Infrared Radiation |
Electromagnetic waves with wavelengths that are LONGER than VISIBLE. |
|
|
Jet Stream |
Bands of high-speed air currents in the atmosphere (they do not touch the ground and stay in the atmosphere)...they help define weather patterns. |
|
|
Phases |
Solid Liquid Gas Plasma |
|
|
Local Winds |
Winds that blow over short distances often confined to small, regional areas...think your valley or your county. |
|

|
Barometer |
An instrument used to measure CHANGES in AIR PRESSURE. |
|
|
Rain Gauge |
A weather instrument used to measure the amount of RAINFALL |
|
|
Hurricane |
A large rotating storm that forms over WARM WATERS in TROPICAL AREAS and have WINDS ABOVE 74 MPH and an AREA of LOW AIR PRESSURE in the CENTER called the "EYE". |
|
|
Tornado |
A VIOLENT rotating COLUMN of AIR usually coming from a THUNDERSTORM and TOUCHING THE GROUND with WIND SPEEDS UPTO 300 MPH. |
|
|
Exosphere |
The outer layer of the thermosphere |
|
|
Ionosphere |
The lower part of the thermosphere |
|
|
Mesosphere |
The layer fo the Earth's atmosphere immediately above the stratosphere |

|
Stratosphere |
The second lowest layer of the Earth's atmosphere |
|
|
Thermosphere |
The outermost layer of the Earth's atmosphere |
|
|
Troposphere |
The lowest layer of the Earth's atmosphere |
|
|
Ozone |
A form of OXYGEN that has 3 OXYGEN ATOMS in each MOLECULE = O3 (not O2) |
|
|
Ozone Layer |
A layer in the Earth's stratosphere at an altitude of about 6.2 miles (10KM) containing mostly Ozone or O3 which absorbs and reflects the majority of harmful UV radiation. |
