Weather is the condition of the atmosphere at 1) What is the difference between weather and climate? Weather is the condition of the atmosphere at a particular time and place. Climate is the general weather of an area over a long period of time.

Draw a picture to show convection Draw a picture to show convection. Give two examples of where this applies on Earth.

Weather is caused by the Uneven heating of Earth’s surface by the sun. 3) What causes Earth to experience weather? Weather is caused by the Uneven heating of Earth’s surface by the sun.

Maritime: wet Continental: dry 4) What is the difference between maritime and continental air masses? Maritime: wet Continental: dry

4) What is the difference between maritime and continental air masses?

5) What is a hurricane? Explain how and where it forms. A low pressure area that gets energy from warm, humid air over water. Have heavy rainfall and high winds. Wind speeds in excess of 75 miles per hour.

6) What is a tornado? A rapidly whirling, funnel shaped cloud that reaches down from a storm cloud to touch Earth’s surface. Usually occur where warm and cold air masses collide.

An area of the United States that has a high 7) What is tornado alley? Why does it experience so many tornados? An area of the United States that has a high frequency of tornados. It is an area where hot and cold air masses regularly “crash” into each other providing the opportunity for severe weather.

7, cont’d) What is tornado alley 7, cont’d) What is tornado alley? Why does it experience so many tornados?

Cold currents originate from the polar regions 10) Where do cold ocean currents originate? Warm? Cold currents originate from the polar regions Warm currents originate from the equatorial region

Cold currents cool areas they pass by. 11) What effect do ocean currents play on the landmasses they border? Cold currents cool areas they pass by. Example, this area is cooler than other areas due to the cold current that passes it

Warm currents heat areas they pass by. 11, cont’d) What effect do ocean currents play on the landmasses they border? Warm currents heat areas they pass by. Example, this area is warmer than other areas due to the warm current that passes it

12) Fill in the following chart for types of air masses: Where it forms Temp Humidity Maritime Tropical 13) Over water, near equator. Warm 15) Wet (rain, etc) Maritime polar 16) Over water, near one of the poles. 17) cold/cool 18) Wet (rain, snow, etc) Continental tropical 19) Over land, near equator 21) Not much that I’m aware of… Continental polar 22) Over land, near one of the poles 23) Cold/cool 24) cold, dry air, so no humidity!

An isotherm is a line that connects points of equal temperature. What is an isotherm? Draw an example of how this is shown on a weather map. An isotherm is a line that connects points of equal temperature.

There is a low pressure system over the Dallas area. 26) Where in Texas is there a low pressure system? There is a low pressure system over the Dallas area.

A stationary front (bumps and triangles 27) What type of front is in New Mexico & Colorado? A stationary front (bumps and triangles are on opposite sides of the “line.”

28) What type of front is moving through Louisiana? A warm front (bumps)

The shading indicates precipitation…rain! 29) What type of weather is occurring in Georgia? The shading indicates precipitation…rain!

Indiana is under the center of a high pressure 30) What type of weather is Indiana experiencing? Indiana is under the center of a high pressure system and is therefore experience clear skies!

Most of California shows nothing happening 31) What type of weather is San Francisco having? Most of California shows nothing happening and like San Francisco, is experiencing clear skies!

It sure looks like rain is coming! Yes, the skies 32) Would you expect it to rain in Minnesota in the next day or two and why? It sure looks like rain is coming! Yes, the skies in Minnesota are currently clear, but it looks like a front, with a bit of rain, is on it’s way.
