DOS Weather Review All of these questions are a part of your study guide. Please answer on your study guide! Monday: a. b. What is a vortex? Spinning of winds caused by earth’s rotation Circulation of liquids and gases; spiral a. b. c. d. What causes a vortex to form? The uneven heating of the earth’s surfaces Force of gravity Earth’s rotation All of the above Monday: a. b. What is a vortex? Spinning of winds caused by earth’s rotation Circulation of liquids and gases; spiral a. b. c. d. What causes a vortex to form? The uneven heating of the earth’s surfaces Force of gravity Earth’s rotation All of the above Tuesday: How does the air above a heated surface move? How does the air above a cold surface move? a. The air will be warmed, and the warm air will hover low to the ground. b. The air will be warmed, and the warm air will rise because it is light. c. The air above will transfer some of its heat to the surface, leaving cool, dense air hovering low. d. The air will transfer some of its heat to the surface, leaving the cooler air to rise forming clouds Tuesday: How does the air above a heated surface move? How does the air above a cold surface move? b. The air will be warmed, and the warm air will rise because it is light. c. The air above will transfer some of its heat to the surface, leaving cool, dense air hovering low. Wednesday: What happens when cold air meets hot air? a. The two air masses form a barrier that keep storms from forming. b. The two air masses diffuse each other; the air temperature averages and creates higher pressure. c. Winds form and weather patterns change, often bringing storms. Wednesday: What happens when cold air meets hot air? a. The two air masses form a barrier that keep storms from forming. b. The two air masses diffuse each other; the air temperature averages and creates higher pressure. c. Winds form and weather patterns change, often bringing storms. Thursday: How do hurricanes form? How do tornadoes form? a. cold, dry air collides with warm, moist air. b. Hot, dry air collides with cold, moist air. c. Low pressure conditions over cold, arctic waters with wind speeds below 118 kmh. d. Low pressure conditions over warm, tropical waters with winds speeds over 118 kmh. Thursday: How do hurricanes form? d. Low pressure conditions over warm, tropical waters with winds speeds over 118 kmh. How do tornadoes form? a. cold, dry air collides with warm, moist air. Friday: How are tornadoes and hurricanes alike? How are tornadoes and hurricanes different? a. Consists of vortex, strong winds, and an eye. b. Diameter and speed c. Damage to homes and lives d. Form in low pressure conditions e. Location of formation Friday: How are tornadoes and hurricanes alike? Consists of vortex, strong winds, and an eye Damage to homes and lives Form in low pressure conditions How are tornadoes and hurricanes different? Diameter and speed vary Location of formation (hurricanes: warm, tropical water; tornadoes: over land where air masses collide)
