Weather Jeopardy Fronts Reading a Weather Map Water Cycle Wind & Air Pressure Precipitation & Severe Weather
The boundary between two air masses is called… Fronts, 100 A front.
What is this the symbol for? Fronts, 200 Cold front
What kind of temperatures might you find behind a warm front? Fronts, 300 Warmer temperatures
Near what part of the front does weather usually occur? Fronts, 400 The front of the front What happened to the cow that was lifted into the air by a tornado?? Udder disaster!
If all fronts are where air masses meet, how can you tell the difference between a warm front and a cold front? Fronts, 500 The front is named for the moving air. (Cold air moving into warm = cold front)
What direction does a stationary front usually move? Fronts, 600 A stationary front is stationary– it doesnt move.
Where would you expect the warmest temperatures to occur? Reading a Weather Map, 100 The warmest temperatures are found in the warm air mass that lies behind the warm front and ahead of the cold front.air masswarm frontcold front
Where would you expect to find the coolest temperatures? Reading a Weather Map, 200 The coolest temperatures are found in the cold air mass that lies behind the cold front.air mass cold front
Where would you expect to find the highest atmospheric pressure? Reading a Weather Map, 300 The highest atmospheric pressure is found at the center of a high pressure system, labeled with a capital H on a weather map.high pressure system
Where would you would expect to find the lowest atmospheric pressure ? Reading a Weather Map, 400
Where would you would expect precipitation to occur? precipitation Reading a Weather Map, 500
What kind of weather can you expect near the Great Lakes? Reading a Weather Map, 600 Rainy
The water boogies down bringing stormy weather. Why? Water Cycle, 100 Water droplets stick together, become larger and heavier. Eventually, gravity pulls them to Earth.
In the water cycle, what occurs after evaporation? Water Cycle, 200 Condensation
In the atmosphere, dust particles are necessary for what to form? Water Cycle, 300 Clouds
What percentage of the Earths water is salt water? Fresh water? Water Cycle, 400 Oceans make up about 97% Freshwater makes up about 3%
Why is the ocean salty? Water Cycle, 500 As fresh water cycles through the water cycle, fresh water evaporates and leaves minerals behind. Over time, the minerals accumulate and becomes more noticable.
Water reservoirs are used for what? Water Cycle, 600 Storing water for later use.
What causes wind? Wind & Air Pressure, 100 Uneven heating of the Earth Whats the difference between weather and climate?? You cant weather a tree, but you can climate!
Cold air is more dense so it … Wind & Air Pressure, 200 Sinks
Why does warm air expand and rise? Wind & Air Pressure, 300 It is less dense than cooler air.
As you move further up, atmospheric pressure … Wind & Air Pressure, 400 Decreases (there is less air pressing down)
What has a more stable temperature, ocean or land? Why? Wind & Air Pressure, 500 The ocean has a more stable temperature because it takes more sun energy to heat.
During the day, where is the air the warmest? Why? What direction is the wind blowing? Wind & Air Pressure, 600 It is warmest over land because land absorbs heat more quickly than water. The breeze will be moving from the cool ocean to the warmer land.
Name three types of precipitation. Precipitation & Severe Weather, 100 Rain, sleet, snow, hail, …
When water evaporates and becomes water vapor, is it a solid, liquid, or gas? Precipitation & Severe Weather, 200 Gas
What happens in the cloud after lightning discharges? Precipitation & Severe Weather, 300 Thunder. When a lightning bolt travels from the cloud to the ground it opens up a hole in the air, called a channel. Once the light is gone the air collapses back in and creates a sound wave that we hear as thunder. The reason we see lightning before we hear thunder is because light travels faster than sound! What happens when it rains cats and dogs?? You have to be careful not to step in a poodle!
Collisions of particles in a thundercloud create an electric charge. After a while, the whole cloud fills up with electrical charges and causes …. Precipitation & Severe Weather, 400 Lightning
This diagram shows the formation of what? Precipitation & Severe Weather, 500 A hurricane
In what part of the Unites States are tornadoes most likely to occur? Precipitation & Severe Weather, 600
