| describe how radiation and convection are both involved in energy transfer in atmosphere | radiation from sun heats atmosphere, convection currents spread heat throughout |
| which has more THERMAL ENERGY a warm swimming pool or a cup of boiling water | the swimming pool: even though its average kinetic energy is much lower, it has so many more particles than the cup of boiling water that it has a greater amount of total energy. |
| why is it not a good idea to wear a black hoodie in summer (use the term Albedo in your answer) | a black hoodie has a low Albedo, meaning it doesn't reflect much sunlight and abosrbs a lot of heat |
| we are surrounded by nitrogen gas (78%) in our atmosphere....so why can't we use it? | Nitrogen gas is in the wrong form, we have to depend on plants and bacteria to conver it into usable forms |
| describe the temperature pattern in the atmosphere and why it changes as it does. | Gets cooler in troposphere due to the surface of earth being warmer, the stratosphere gets warmer due to ozone trapping heat, the mesophere cools again due to being far from the warm surface and no ozone, the themosphere then gets really hot due to intense solar radiation |
| describe three special features found in the atmosphere | clouds in troposhphere, ozone layer in stratosphere, auroras (northern lights) in thermosphere |
| why is the equator so much warmer? | the sun is more directly overhead, so there is more energy per square meter (more insolation) |
| if the "barometer is falling" what kind of weather is likely? | unstable, cloudy weather, possibly precipiation (a low pressure system) |
| if the "barometer is rising" what kind of weather is likely? | clear skies, stable weather (a high pressure system) |
| why does a high rotate clockwise and lows counter clockwise? | Coriolis effect causes wind to bend is it flows form high to low |
| as air rises it cools....what happens to the realtive humidity? | relative humidity goes up....cold air can't hold as much moisture |
| why does a "good" coffee mug weigher more than a cheap one | most likely because the good mug has two layers with an insulator in between...cheap mugs do not |
| why is it so smoggy near Abbotsford during the day? | A sea breeze develops during the day (due to land heating faster) that blows the smog from Vancouver inland to Abbotsford....reverses at night |
| Why do North East trade winds bend to the right? | The spinning of the earth causes the "Coriolis effect" which makes the winds appear to bend. |
| A "polar easterly" prevailing wind comes from which direction? | From the east. |
| Why do flights from Hawaii to Vancouver (flying east) take less time than flying the other direction? | Flying east gets a "tailwind" from the jetstream, which travels west to east. |
| This is likely to happen when a cold front and warm front meet. | precipitation |
