Question 1

Used to measure temp

Answer 1

Thermometer

Question 2

Used to measure humidity

Answer 2

Hygrometer

Question 3

Used to measure atmospheric pressure

Answer 3

Aneroid barometer

Question 4

Used to measure wind speed

Answer 4

Anemometer

Question 5

Used to measure the amount of liquid precipitation

Answer 5

Rain gauge

Question 6

What are high and low pressure systems associated with

Answer 6

High- cool air masses sink and do not rise above to form clouds and storms so they bring clear and nice weather

Low- warm moist air conditions cause the air to rise and create clouds so they are associated with stormy weather

Question 7

How do we predict weather

Answer 7

• study of weather is called meteorology
• weather balloons in altitudes of 30km carry small radio transmitters that tell us the temp, humidity, and atmospheric pressure
• this info is fed into a computer for analysis from many balloons across america
• aircraft also collect info
• weather models try to predict future weather

Question 8

Explain how energy from the sun reaches the earth and how its distributed

Answer 8

• the sun’s energy reaches the earth in radiant form
• ozone absorbs UV radiation during ozone formation, so does water vapour
• the earth surface’s albedo determines energy absorption and reflection
  
  • some energy changes into heat and is used to drive the water cycle and ocean currents
  • gasses in air capture the IR and trap its energy and warm the earth (greenhouse effect)
• energy helps in cloud formation and is absorbed by plants for photosynthesis

Question 9

What is a jetstream

Answer 9

Narrow region of fast moving air that is caused by the collision of air masses from the northern hemisphere and the southern hemisphere. The air from the north is cooler and the air from the south is warmer. High and low pressure systems get pushed and follow the jet stream so forecasters use the jet stream to locate these pressure systems.
