the colder the temperature Latitude Ocean Currents Winds spread heat energy
from the equator to the poles Winds and Air Masses Air temperature decreases as you go up a mountain

The decrease in temperature also affects the type of vegetation Elevation Relief Near Large Bodies
of Water this is because the same amount of energy is spread over a large surface area the equator is hot all year because it gets direct sunlight all year long
as you move towards the north pole and the south pole the climate gets colder In summer the northern hemisphere is tilted towards the sun so we have longer days and more energy. In the winter, the northern hemisphere is tilted away from the sun so we have shorter days and less energy. Cold ocean currents
cool the land next to them.
Warm ocean currents
warm the land next to them. Labrador Current:
cools Newfoundland and Labrador

Gulf Stream:
brings warm, moist air to Halifax

North Pacific Current:
brings warm, moist air to Vancouver Examples: These are called WESTERLIES Most winds in Canada travel from west to east air masses that come from over water are moist
air masses that come from over land are dry
air masses that come from equatorial areas are warm
air masses that come from the poles are cool An air mass is a large volume of air that has the climate conditions of the area where it was created travels at 300-500 km/hr, 9-18 km above the earth's surface Jet Stream a fast-moving wind high in the atmosphere allows warm, moist air to come to Canada in summer moved south in the winter by the cold, Polar air mass from the Arctic W O E R Mountain ranges cause precipitation and affect the flow of air masses N Large bodies of water
moderate the temperature
of the land beside them In the winter, the ocean cools off more slowly than land resulting in a milder winter.

And in the summer, the ocean warms up more slowly resulting in a cooler summer. For example, Vancouver Maritime Climate This is known as a L In the summer, land that is far away from the ocean heats up quickly.
Conversely, in the winter, land that is far away from the ocean cools off quickly. Continental Climate This is called a For example, the Saskatchewan For example, the Coast Mountains
