Study Guide for Unit #2 Chapters 5, 6, 8 – 13 1.) How does weather differ from climate? Which two variables determine climate? The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time. 2.) Latitude determines _____________, while altitude determines ____________. b) amount of sunlight, temperature 3.) Earth rotates. This rotation influences wind direction and cause the _________ Effect. a) Coriolis 4.) What is the “Rain Shadow Effect”? Where in North America do you see the rain shadow effect impacting regional climate? A zone on the leeward side of a mountain range that Mountains, which force air to rise, remove moisture from humid air, the air cools as it grains altitude, cloud form, and precipitation occurs, primarily on the windward slopes of the mountains. as the air mass moves down on the other side of the mountain, it is warmed, thereby lessening the chance of precipitation of any remaining moisture. It exists on the west coast of North America. 5.) The ________ side of a mountain range tends to have more precipiatation than the ________ side of the mountain range. d) windward, leeward 6.) What is the albedo effect? Reflectivity Albedo is the proportional reflectance of solar energy from earth's surface Light from the sun is energy --> When this light falls on an object some of it is reflected -->Some of the light is absorbed -->The Albedo is a measure of how much light a surface reflects -->It is mostly determined by the color and texture of the surface -->The Albedo Effect can change our climate. Snow covered land reflects nearly all the light that falls on it-->However dark colored land will absorb nearly all of the light energy turns to heat-->As the world’s climate warms, the snow in some areas of the artic has melted leaving the ground underneath exposed-->The exposed ground absorbs more of the suns energy causing further warming meaning more snow will melt. This is an example of positive feedback 7.) List three conditions that influence global wind patterns. Be able to explain how these three conditions cause wind!! Uneven heating of earth’s surface by sun earth’s axis is on a 23◦ angle, which is why winter is the southern hemisphere is summer in the northern hemisphere.

Rotation of earth on its axis: warmer air at the equator wants to move towards cooler areas as earth rotates, the equator spins faster than the poles causes warm air from the equator to move northeast and southeast. Properties of air, water, and land the cool, dry air sinks back towards earth where it is warmed and picks up water vapor. This warm air now wants to rise, so it moves towards the area of low pressure. 8.) How does atmospheric convection (or a convection cell) help determine the latitude of deserts and
