  1. Earth Science Review The wearing away and movement of sediment by wind, water, or ice is called_______________ Erosion Weathering Deposition Sediment

  2. Earth Science Review Why are “river rocks” usually smoother than other rocks? River rocks are made of a different material than other rocks River rocks have been weathered by wind which makes them smother River rocks have a smaller mass than regular rocks River rocks have been weathered by water which makes them smoother.

  3. Earth Science Review What is the best way to test a soil’s ability to hold water? Mix water with a pile of soil and see if the water changes temperature Pour soil into a bowl of water, stir it up, and see if it disappears Pour water through a funnel of soil and see how much water drips out into a cup Add soil to a beaker full of water and see if the soil sinks

  4. Weather forecasting is a prediction of what the weather will be like in an hour, tomorrow, or next week. Weather forecasting involves a combination of computer models, observations, and a knowledge of trends and patterns. By using these methods, reasonable accurate forecasts can be made up to seven days in advance. How do meteorologists forecast the weather?

  5. A high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds. When viewed from above, winds spiral out of a high-pressure center in a clockwise rotation in the Northern Hemisphere. These bring sunny skies. A high pressure system is represented as a big, blue H. What is a High Pressure System? H

  6. A low pressure system is a whirling mass of warm, moist air that generally brings stormy weather with strong winds. When viewed from above, winds spiral into a low-pressure center in a counterclockwise rotation in the Northern Hemisphere. A low pressure system is represented as a big, red L. What is a Low Pressure System? L

  7. A front is a boundary between two different air masses, resulting in stormy weather. A front usually is a line of separation between warm and cold air masses. What is a front?

  8. A cold front is a boundary between two air masses, one cold and the other warm, moving so that the colder air replaces the warmer air. A cold front is represented as a blue line with the teeth pointing toward the direction on movement. What is a cold front?

  9. A warm front is a boundary between two air masses, one cool and the other warm, moving so that the warmer air replaces the cooler air. A warm front is represented as a red line with half circles pointing toward the direction on movement. What is a warm front?

  10. A stationary front is a boundary between two air masses that more or less doesn’t move, but some stationary fronts can wobble back and forth for several hundred miles a day. A stationary front is represented as an alternating warm and cold front symbol. What is a stationary front?

  12. Lets have some fun predicting the weather and learning how to read a weather map. • http://www.edheads.org/activities/weather/frame_loader.htm • Main web page to Ed: http://www.edheads.org/activities/weather/index.shtml Map Reading Practice
