Transfer of energy
Science 10
| Term | Definition |
|---|---|
| conduction | direct contact, touch |
| convection | fluids, current, move matter and heat |
| electromagnetic radiation | transfer of energy by waves travelling from a source |
| heat | transfer of kinetic energy |
| kinetic energy | energy of a particle or object due to its motion |
| kinetic molecular theory | all matter is made up of particles |
| temperature | average amount of kinetic energy |
| thermal energy | total amount of kinetic energy |
| thermal | increasing motion of particles |
| density | how far particles are from one another mass/volume |
| infrared | heat radiation |
| humidity | water vapour, |
| particles move from ______ to ______ | hot to cold |
| act of______ creates thermal energy | motion |
| expand density goes ______ | down |
| radiation | wave that comes from a source |
| clouds block _______ | radiation |
| atmosphere | layers of gases that extend above a planet's surface. |
| troposphere | ground, densest, temp ↓ -55, convection currents |
| stratosphere | second,temp ↑ 0, blocks uv, weather, planes |
| mesosphere | middle, temp ↓ -100, shooting stars |
| thermosphere | temp ↑ 3000, northern lights |
| exosphere | last |
| kmt | theory that explains the transfer of energy |
| coriolis effect | difference in pressure caused by rotation, refers to wind |
| ozone layer | layer in the stratosphere |
| prevailing winds | winds that are typical for a certain region, moist air masses |
| sea breezes | winds that blow from water to land |
| albedo | amount of radiation reflected by a surface |
| pressure moves | from high to low |
| convection current | hot air moves to cold air causing a current |
| atmosphere made up of? | 78% nitrogen, 21% oxygen, 1% trace |
| 3 weather points | humidity, altitude, temperature |
| atmospheric pressure affected by? | altitude and temperature |
| dry air is_____ than w.v | denser |
| 4 air masses | continental polar, |
| 3 points of high pressure | low humidity, blue skies, many particles |
| 3 points of low pressure | travel over warmth, air thickens, precipitation |
| onshore breezes | morning, convection current, water to land |
| offshore breezes | evenings, reverse convection current, land to water |
