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 |
