Study Guide – Weather and Atmosphere

1. Name 3 Weather Conditions that we recorded

PRECIPITATION, TEMPERATURE, CLOUD COVER, HUMIDITY, ETC.

2. What are the units of temperature in the:                                                                                      a. customary system                               ^OF

b. Metric (International)System

                                   ^OC

3. What is humidity?

AMOUNT OF WATER VAPOR IN THE AIR

4. What is Risk? 

LIKELKIHOOD OF FUTURE EVENT BASED ON FREQUENCY OF PAST EVENTS

5. For which weather disasters do we face high or severe risk in Connecticut?

HURRICANES.  FLOOD RISK HIGHER IN FAIRFIELD COUNTY PER MAPS IN BOOK

6. Name 3 Factors that affect climate:

LATITUDE, OCEANS INCL. CURRENTS, AMOUNT OF ENERGY FROM SUN THAT HITS SURFACE, LANDFORMS

7. How is climate different from weather?  Explain.

WEATHER IS OUTDOOR TEMPERATURES AND CONDITIONS OVER A SHORT PERIOD OF TIME AND CLIMATE IS OUTDOOR TEMPER-ATURES AND CONDITIONS OVER A LONG PERIOD OF TIME.

8. What are the States of matter?

PLASMA, LIQUID, SOLID , GAS

9. What are the words used to describe the change from one state of matter to another?  EVAPORATION, CONDENSATION, MELT, FREEZE

10. Name and describe the 4 parts of the water cycle.  Give examples of each.

EVAPORATION - liquid changes to gas. Ex: WATER DRYING UP FROM LAKE OR PUDDLE

CONDENSATION - gas changes to liquid. Ex: FOG, MIST, CLOUDS

PRECIPITATION - water falling from the sky; ex: RAIN, SNOW, SLEET, HAIL, FREEZING RAIN

COLLECTION (Runoff + Groundwater) - water from precipitation that flows down to the ocean. Ex: RIVERS, LAKES; UNDERGROUND AQUIFERS.

11. Identify which state of matter/water is found in each part of the water cycle.

EVAPORATION - gas

CONDENSATION - liquid

PRECIPITATION – liquid or solid

COLLECTION (Runoff + Groundwater) – liquid, could be solid

12. What gases are found in the Earth’s atmosphere?  Which gas is at the highest percentage?

            78% N, 21% O, 0.9% Ar; CO2, Neon, Helium, Hydrogen, Krypton, Methane total less than  .1%

13. Name the Earth’s atmospheric layers in order from lowest to highest. 

TSMT – Trophosphere, Stratosphere, Mesosphere, Thermosphere

14.   Compare the composition of the Earth’s atmospheric layers.

                            (Hint: “Composition ” means: what it’s made of)

ALL GASES IN THE LAYERS EXIST IN THE SAME PERCENTAGES, EXCEPT THAT THERE IS SOME WATER VAPOR IN THE TROPOSPHERE AND LOWER STRATOSPHERE, BUT NONE IN THE HIGHER LAYERS.

15. What is air pressure?

THE FORCE OF AIR PUSHING DOWN ON AN AREA

16. What is the formula for air pressure?

P = F/A
