Energy- chapter 10
how energy transfers naturally
Term | Definition |
---|---|
conduction | Directly transferred heat |
convection | heat movement caused by temperature |
electronic energy | radient energy that travels in waves at a high speed |
KMT | A theory that explains the transfer of energy |
Thermal energy | Energy contained in a system that's responsible for temperature |
Atmosphere | Layers of different gases that surround the earth |
Coriolis effect | apparent force caused by earths rotation |
Ozone layer | A layer in earths stratosphere |
Prevailing winds | Winds that are typical for a certain region |
Sea Breezes | Winds that blow from water to land |
KPa | kilopascal measuring system |
Radiation | Energy that comes from a source and travels through space at the speed of light. |
Albedo | Amount of radiation reflected by a surface |
how does Pressure move? | from high to low |
key word for temperature | Average |
key word for Thermal | Total |
key word for Heat | transfer |
Convection current | the process in which warm material expands and rises while cool material contracts and falls |
what is the atmosphere made up of? | 78% Nitrogen, 21% oxygen, 1% other gases |
what are the four atmospheric layers? (in order) | Troposphere, Stratosphere, Mesosphere, thermosphere, Exosphere |
what are the three points of weather? | Altitude, Temperature, Humidity |
how is atmospheric pressure measured | By a barometer |
What is atmospheric pressure effected by? | Altitude and Temperature |
does it get hotter or colder with more W.V | hotter |
which is denser/heavier? dry air or W.V | dry air |
what are the four air masses? | 1. Continental polar 2. Continental tropical 3. martime tropical 4. martime polar |
what are the three main aspects of high pressure? | 1. low humidity 2. blue skys 3. many particles |
what are the three main aspects of low pressure? | 1. Travel over warmth 2. Air thickens 3. Clouds/percipitation forms |
what are prevailing winds? | Moist air masses |
what are three main aspects of OnShore breezes? | 1. occurs mostly in the morning time 2. Regular convection current (counterclockwise) Goes from water to land |
what are the three main aspects of OffShore breezes? | 1. occurs later on in the day 2. reverse convection current (clockwise) Convection current goes from land to water |
what are the two main points about Coriolis effect | 1. Refers to wind 2. It's a difference in pressure according to spin |
