4. TNReady Question

5. Answer D.

7. Check for Understanding
What is the definition for weather?

8. Answer
Definition- the daily conditions of the Earth’s atmosphere

9. Four Factors that Affect Weather
1. Heat- the sun’s rays strike the Earth at different angles making temperature differences on Earth
2. Air Pressure- depends on the density of the air (cold air is more dense= more pressure)
3. Wind- air pressure differences cause air movement (convection currents)
4. Moisture- Relative Humidity- condensation in the atmosphere causes clouds and rain

10. Check for Understanding
What four factors affect our weather?

11. Answer
Heat, Air Pressure, Wind, and Moisture affect weather.

12. Weather or Climate? Weather and Climate are NOT the same.
Weather is the DAILY events.
Climate is an AVERAGE weather for the area.

13. Check for Understanding
What is the difference between weather and climate?

14. Answer Weather is the daily events.
Climate is an average weather for the area.

15. Four Weather Factors Make Events
Each factor (Heat, Air Pressure, Wind, and Moisture) creates an event that can be measured.
Temperature- hot or cold
Cloudy or Rainy- moisture in the air
Wind- air movement
Pressure- density of air

16. Check for Understanding
What are some weather events?

17. Answer
Temperature, Cloudy or Rainy, Wind, and Pressure

18. How do we measure weather events?
Draw and Label on note page:
1. Anemometer- measures wind speed

19. How do we measure weather?
2. Hygrometer- measures moisture (water vapor) in the air

20. How do we measure weather?
Thermometer- measure the temperature (kinetic energy)

21. How do we measure weather?
Barometer- measures air pressure

22. Check for Understanding
What weather instrument measures…
1. Air Pressure?
2. Moisture?
3. Wind speed?
4. Temperature?

23. Answer 1. Air Pressure- barometer 2. Moisture- hygrometer
3. Wind speed- anemometer
4. Temperature- thermometer
