30 Questions
How does a large body of water impact the temperature of adjacent land in the summer?
It cools the land
What effect do ocean currents have on coastal regions?
They influence temperature and precipitation patterns
What weather condition results from the meeting of the Labrador Current and Gulf Stream?
East Coast Convergence Zone storms
What is an air mass primarily characterized by?
Consistent temperature and humidity
How do air masses originating over water differ from those originating over land?
Land-originated air masses are more humid
What is the primary reason for Canada's climate having great variety?
Influence of ocean currents and westerly winds
What is the primary cause of wind?
Interaction of different air masses
Which location marks the southernmost point of mainland Canada?
Point Pelee, Ontario
What is the latitude of Cape Columbia, the most northerly point of Canada?
Approximately 83.13° N
How does an increase in elevation affect temperature?
Temperature decreases
Why does temperature decrease with an increase in elevation?
Factors such as atmosphere and albedo
Besides proximity to the sun, what other factors influence temperature?
Atmospheric conditions and albedo
What primarily causes wind?
Unequal heating of the Earth's surface
How do hurricanes in the Northern Hemisphere rotate?
Counterclockwise
What type of precipitation occurs due to warm air being slowly pushed up over cold air?
Cyclonic (Frontal) Precipitation
How is a rain shadow created?
By warm air being pushed up over mountains
What temperature does water need to be for hurricanes to develop?
27 degrees Celsius
Which type of precipitation occurs due to the sun heating the ground and creating clouds throughout the day?
Convectional Precipitation
What is the main difference between a tornado watch and a tornado warning?
A watch means a tornado is possible, while a warning means a tornado has been detected.
What is the role of the greenhouse effect in maintaining Earth's temperature?
It keeps the Earth 30 degrees celsius warmer than it would otherwise.
What is the primary cause of the 'enhanced' greenhouse effect?
Burning of fossil fuels and methane emissions
Why is carbon dioxide often linked to the 'enhanced' greenhouse effect?
It contributes to over 60% of the 'enhanced' greenhouse effect.
Which of the following is NOT listed as a natural cause of the 'enhanced' greenhouse effect in the text?
Burning of fossil fuels
What do 97% of climate scientists agree on regarding climate-warming trends?
The trends are extremely due to human activities.
Why does the temperature decrease as you move away from the equator?
The sun's energy spreads out and loses its heating power away from the equator.
Why does the temperature of air passing over an ocean current change?
The temperature of the ocean current affects the temperature of the air passing over it.
How does elevation impact temperature?
The higher you go, the cooler the temperature becomes due to air expansion and loss of heating power.
Why do mountain barriers create wet conditions on the windward side?
Mountains block warm, moist air masses, forcing them to release precipitation on their windward side.
How does nearness to water affect climate?
Larger bodies of water moderate temperatures, resulting in cooler summers and warmer winters.
Why does Canada have varied climate conditions?
Canada's climate is influenced by its diverse topography and proximity to water bodies.
