What are the three ways heat energy is transferred from Earth to atmosphere? |
- Conduction - Convection - Radiation |
|
|
True or False: Conduction is heat transfer by the mass movement of fluid. Hot molecules vibrate more, fluid expands and rises, and cold air replaces it. |
FALSE: Convection |
|
|
Name this energy transfer process: Direct contact between molecules; relies on temperature difference between the two substances. |
Conduction |
|
|
Name the 3 ways solar energy can be transported through the atmosphere. |
- Reflected (by dust and clouds) through the atmosphere - Absorbed through the atmosphere - Transmitted through the atmosphere |
|
|
True or False: Weather is the result of the re-distribution of energy absorbed buy the Earth's atmosphere. |
True. As much energy that is received by the Earth is also radiated away from the Earth. |
|
|
From Earth outwards, what are the 4 major layers of the atmosphere? |
Troposphere, Stratosphere, Mesosphere, Thermosphere |
|
|
True or False: Atmospheric Pressure is controlled by Temperature, Radiation, and Water Vapour Content. |
False: It's controlled by temperature, WVC, and movement of air. |
|
|
_________ is the boundary between air masses of different densities; usually as a result of differences in temperature. |
Weather Front. |
|
|
Thunderstorms develop in what type of cloud? |
Cumulus cloud. |
|
|
True or False: The formation of lightning involves an exchange of positively charged ions on the ground to negatively charged ions in a thundercloud. |
True. |
|
|
True or False: Tornados' energy sources involve heat from condensing moisture. |
True. |
|
|
The _______ scale measures tornado intensity. |
Fujita Scale |
|
|
True or False: Tornados don't occur in Atlantic Canada. |
False. They can occur, usually more-so in New Brunswick than in NS. |
|
|
The Ice Storm of 1998 affected which two provinces the most? |
Quebec and Ontario. |
|
|
Storm surges are most susceptible in __________ coasts. |
Low-lying |
|
|
Hurricanes' energy source is from ______ water on sea surface. |
warm; sea surface >26 degrees C |
|
|
True or False: Hurricanes can occur in Hawaii. |
False: no hurricanes where surface winds are opposite to winds aloft. |
|
|
True or False: An extratropical cyclone requires: 1) Strong temperature gradient near the surface; 2) Low winds in the lower troposphere. |
False: They require 1) and strong winds in the upper troposphere. |
|
|
The two different types of jet streams are..? |
1) Polar jet streams; 2) Sub-tropical jet streams |
|
|
True or False: Extra-tropical cyclones form through: - A wave forming where winds diverge in a stationary front (winds parallel). - A surface low develops through cold air being pushed south and warm air being pushed north - Cold air moves faster, pushing warm air aloft |
True... Sorry for such a crappy question |
|
|
True or False: Droughts affect the US and Canada more than any other natural disaster. |
True |
