PHYSICAL SCIENCE

**TAKE NOTES IN YOUR SCIENCE SPIRAL REVIEW QUESTIONS

1. Why do we have moderate temperatures on lands bordering the oceans?

Waters high specific heat capacity—it retains heat longer. The fact that water resists changes in temperature affects the climate of areas close to the oceans. Recall the comparison of coastal San Francisco and continental Wichita. San Francisco has small seasonal variations, whereas Wichita shows strong seasonal fluctuations—cold winters and hot summers.

2. Earth’s present atmosphere likely developed from gases that escaped from its interior during volcanic eruptions. What two principal atmospheric gases were produced by these eruptions?

Probably much like the gases found in the volcanic

eruptions of today—water vapor, and carbon dioxide.

3. What elements make up today’s atmosphere? Primarily nitrogen and oxygen, with small amounts of water vapor, argon, and carbon dioxide.

4. Why doesn’t gravity flatten the atmosphere against Earth’s surface?

Energy from the Sun energizes atoms and molecules and keeps them in motion.

5. In which atmospheric layer does all our weather occur?

Troposphere.

6. Does temperature increase or decrease as one moves upward in the troposphere? As one moves upward in the stratosphere?

Decreases; increases.

MANDATORY BONUS QUESTION – WHY IS THE ANSWER TO # 8 WHAT IT IS…

7. What does the angle at which sunlight strikes Earth have to do with the temperate and polar regions?

The lower angle in the sky spreads light over a larger area, reducing the amount of heat energy these regions receive from the Sun.

8. What does Earth’s tilt have to do with the change of seasons?

The tilt of the Earth is what is responsible for the seasons.

9. How does radiation emitted from Earth differ from that emitted by the Sun?

Earth radiates long-wavelength radiation; the Sun emits short-wavelength radiation.

10. How is the atmosphere near Earth’s surface heated from below?

It is heated from below by terrestrial longwave radiation.

HW = RQ 11-20 FOR CH 3011. What is the underlying cause of air motion?

The unequal heating of Earth’s surface.

12. What causes pressure differences to arise, and hence causes the wind to blow?Unequal heating of Earth’s surface leads to temperature differences, which cause the pressure differences to drive wind.

13. In what direction does Earth spin—west to east or east to west?The Earth rotates in a counterclockwise direction—west to east.

14. What does the Coriolis force do to winds? To ocean currents?It deflects wind and water currents.

15. Why are most of the world’s deserts found in the area known as the horse latitudes?As air from the sweltering doldrums rises, it divides and spreads out either to the north or south. At about 30° N and 30° S latitudes, the air has cooled enough to descend toward the surface. As it descends, it compresses and warms resulting

in a high-pressure zone—a belt of hot, dry surface air. On land, these high-pressure zones account for the world’s great deserts.

16. Why are eastbound aircraft flights usually faster than westbound ones?The upper-level westerly moving winds of the jet stream account for faster-moving eastbound aircraft. As the jet stream moves from west to east it carries along everything in its path. To save time and fuel, air pilots seek the jet stream when traveling west to east and avoid it when traveling east to west.

17. Salinity of the ocean varies from one place to another. What two factors lead to an increase in salinity? What two factors lead to a decrease in salinity? Salinity varies according to increases or decreases in fresh water supply. Salinity increases as fresh water leaves the ocean by evaporation and formation of sea ice. Salinity decreases as fresh water enters the ocean as runoff from streams and rivers, precipitation, and the melting of glacial ice.

18. Why do waves become taller as they enter shallow water?As waves enter shallow water, they slow down. The wave period remains unchanged because the swells from deeper waters continue to advance. As a result, incoming waves gain on leading slower waves and the distance between waves decreases. This concentration of water in a narrower zone produces higher, steeper waves.

19. Why are all tides greatest at the time of a full or new Moon?Because the Moon and the Sun are aligned.

20. When would the highest high tides occur: during a spring tide or during a neap tide?Spring tide.

HW WAS: 3=FACTORS ? 4=PROPERTIES OF EXPONENTS

MONDAY = TEST DAY

Remember – FOR ALL CLASSES – to note every 30 minutes!!!option 1 = do 30 min on each class hw - start with math - then you must move on to another class…then come back if you need to…option 2 = there is no option 2.YOU NEED TO SET A TIMER FOR 30 MIN.4=PROPERTIES OF EXPONENTS

ANSWERS: GRADE ‘EM YOU MUST…

**************************************PRECALC:HW 5/6 = ERP 1-20 TRY ALL DO ALL IN SPIRAL SAW FOR EVERY PROBLEM ELSE = 0 CREDIT.
