geography unit 2

2. Weather Systems, Climatic Change, Microclimates

parcels of air rising through the environment have relationships with the surrounding air that causes them to continue to rise or sink beyond the initial triggers
the presence of continents and oceans strongly influences weather phenomena at a smaller scale than the planetary systems
at a smaller scale, human activities such as the creation of large settlements and cultivated lands, have influenced atmospheric conditions in specific areas (microclimates)
human activity has significantly influenced the earth's atmospheric conditions. it is accelerating natural climate change by varying the composition of the air
carbon pollution is resulting in global warming with potentially disastrous consequences such as rising sea level and unpredictable weather. the results of accelerated global warming are becoming more and more apparent
atmospheric pressure falls with height and the parcel expands losing heat
adiabatic cooling the process by which the temperature of an air mass decreases as the air mass rises and expands
there are 2 different adiabatic lapse rates depending on the relative humidity of the rising parcel of air
the 2 different adiabatic lapse rates -dry adiabatic lapse rate (DALR) -saturated adiabatic lapse rate (SALS)
dry adiabatic lapse rate ??
saturated adiabatic lapse rate ??

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
