CGC1D1/1P1 LOWER NEAR WATER Mr. J. McKinnon L for ______________ O for ______________ W for ______________ E for ______________ R for ______________ Near ______________ Latitude The earth's _________ causes the sun's energy to be less ____________ at the poles than near the ________. Places closer to the equator are _________ than places further north or south. Warmer air can hold more _________ than colder air; therefore, areas _______ away from the equator are _______ than areas closer to the equator. Ocean Currents An ocean current (like a _______ within the ocean water) can be warmer or cooler than the water around it. Air above the water is affected by the __________ of the water as it passes over. The west coast has a warm ocean current called the _______________. Brings warm, moist air to the Pacific coastal areas. The cold __________ flows from the north along the coast of Labrador. The warm _________ flows from the south along Nova Scotia and Newfoundland. Where they meet, _____ is created. Air Mass Initials Temperature Moisture CA Cold to very cold Dry Winds and Air Masses Continental Arctic An air mass is a large volume of Continental Tropic CT Hot Dry air that has the _________ and ____________ of the location mT Warm Moist where it was formed. If it formed Maritime Tropic over an ______, it's wet. If it Maritime Polar mP Cool to cold Moist formed over _______, it's dry. If it formed in the _______, it's cold. If it formed in the _______, it's warm. Winds blow these air masses from one location to another. In Canada, most of our winds (the _________ winds) come from the west. They are called the "_________". The Westerlies are controlled by the _________ (a current of fast-moving air high in the atmosphere). North of the jet stream it is colder than south of the it. In the summer, the jet stream moves _________, so we get warmer weather. In the winter, the jet stream moves further ________ and we get colder weather. Elevation Elevation is the _______ the land is above sea level. As air rises, it ___________ due to the decrease in air pressure. As air expands, it _______. Since colder air cannot hold as much moisture (water vapour) as warmer air, when the air cools, the water vapour condenses into liquid water droplets. Once the droplets are big enough, they will fall as _____ or _______, depending on the __________. Summary: Areas lower in _______ tend to be warmer than areas higher in elevation. This factor is not dependent on how the land is shaped. An area of flat land at a higher elevation is colder than an area of flat land at lower elevation. Relief As air is forced over ___________ barriers, it cools and creates ___________. Near Water Areas that are close to water have their climate _______ by the water so that the summer temperature are not as hot and the winter temperatures are not as cold. Creates _________ climates near water and __________ climates away from water. Which of the above factors do you think affect the climate of Whitby?
