Chapter 6 Study Guide Review Power Point
Answer: Gravity What causes air pressure?
What happens to air pressure as you move from the base of a mountain to the top of a mountain? Answer: Air pressure decreases. Look at the picture of a mountain.
Answer: Gas particles in cool air are closer together than those in warm air. Why is cool air heavier than warm air?
Answer: Large bodies of water affect the temperature of the air above them. How can ocean currents affect the climate of an area?
…continental polar air mass? Answer: cold, dry air …maritime polar air mass? Answer: cold, wet air What type of air exists in a… …maritime tropical air mass? Answer: warm, wet air …continental tropical air mass? Answer: warm, dry air
Answer: a cold front What does this symbol on a weather map show? What about this symbol? Answer: a warm front
Answer: equator At which place on Earth do the Sun's rays shine at the most direct angle?
Answer: warm ocean water What is the source of a hurricane's energy?
Answer: Layers of wind in a storm must blow at different speeds or in different directions. What must happen for a tornado to form?
Answer: Air pressure also exists inside the bag. Why doesn't a closed paper bag collapse under the weight of Earth's atmosphere?
Answer: The warm air will rise. What will happen to warm air that is surrounded by cold air?
Answer: tracking tornadoes What is one important use for Doppler radar?
Answer: 1. An anemometer measures wind speed. 2. A barometer measures air pressure. 3. A rain gauge measures the amount of rain that has fallen. 4. A hygrometer measures the moisture in air. Name four tools used by weather forecasters. Tell what type of information each tool provides.
All places are not heated equally, so there are differences in air temperatures all over. Convection currents form because warm air rises and cool air sinks. How does Earth’s uneven heating cause convection currents to form?
Warm front: warmer air moves against and rises above cooler air. A long period of precipitation is followed by higher air temps. Name and describe three types of weather fronts. Cold front: cooler air moves against warmer air. This warm air rises quickly. Heavy rain falls and temperatures drop. Stationary front: a boundary between 2 air masses moving back and forth. Weather remains cloudy with some rain.
