Where does water from a pond, lake or river get most of its energy to evaporate?
What type of air masses bring cold, dry air which affects the northern US during the winter months?
If you live far from the ocean, it is likely you will have a _______________climate.
Where on Earth do the sun's rays hit least directly?
Earth's atmosphere traps energy from the sun. This allows water to exist as a ____________.
What does the tilt of Earth's axis as it revolves around the sun cause?
Where do the sun's rays hit most directly?
What best describes what scientists measure when they compare the readings of wet and dry bulb thermometers?
What do meteorologists say are caused by uneven heating within short distances or small areas?
What happens to solid molecules when they are heated?
move farther apart (fast moving/less dense)
Molecules in cooler substances _________.
are moving slower (more dense/closer together)
What are caused by uneven heating over long distances or larger areas?
Convection takes place because _______air is more dense than _____air.
Water vapor is water in the form of a _____.
What are the steps of the water cycle?
- 1. Water is heated by sun's energy.
- 2. Water evaporates/turns into water vapor.
- 3. Water vapor rises.
- 4. Water vapor cools then reaches its dew point. (turns back into a liquid)
- 5. Condensation on foreign particles in the air forming clouds.
- 6. Saturation occurs.
- 7. Precipitation.
Mild marine climates, like much of the west coast of the US, have ______ winters and _____summers.
warm winters and cool summers
What often happens when air moves from high pressure to low pressure?
Air in the atmosphere has pressure because air has ______.
Land cooling off faster than water causes _________breezes.
What are the names of the two snowiest cities in the US?
Rochester and Buffalo, NY
_______are caused by differences in air pressure and temperature.
Air pressure decreases as you move away from the Earth. Further in the atmosphere, however, air pressure first _____ then_____.
increases then decreases
Land heating up faster than water causes ____ breezes.
Why does one hemisphere have summer at the same time the other hemisphere has winter?
Due to the tilt of the Earth on its axis, one hemisphere receives direct rays/energy from the sun, causing warmer temperatures during the summer months. The opposite hemisphere receives less direct rays/energy from the sun at the same time, causing cold winter temperatures.
Why does Lake-Effect Snow occur?
Cold, dry air masses (continental polar)from the north travels over the Great Lakes. Land around the lakes cools much more rapidly than the water in the lakes. Warmer lake water is evaporated as the continental polar air mass moves over the warmer water. The evaporated water from the lakes rise, cool, condense and form clouds. Clouds get saturated and precipitate A LOT of snow on the land near the lake. Typically the precipitation is about 3 meters per year.
Make a weather prediction:
Temperature:21 degrees Fahrenheit
Air Pressure:29.5 inches and falling
Cloud Type: stratus
Cold/snow likely 12-24 hours
