I don’t expect someone to fully answer these all for me, but Earth Science is a very weak subject for me and i’d like to do well. So if someone could at least help me out by eliminating one or two wrong answers that would amazing. Thank you all very much. Have a wonderful day and God bless.

1. Complete the statement by selecting the correct ending phrase. Statement: Winds blow…

a. counterclockwise in the northern hemisphere and clockwise in the southern hemisphere

b. from the cold fronts toward warm fronts

c. from areas of low pressure to areas of high pressure

d. from areas of high pressure to areas of low pressure

2. What causes the wind zones of the earth?

a. the presence of sustained low pressure over the poles and high pressures over the equator and the Coriolis effect

b. the presence of sustained high pressure over the poles and low pressures over the equator and the Coriolis effect

c. the action of the jet stream along with the presence of low pressures over the poles

d. the high insolation over the poles and low insolation over the equator along with the Coriolis effect

3. What name is given to a warm and moist air mass?

a. tropical maritime

b. tropical continental

c. polar maritime

d. polar continental

4. What is orographic uplift?

a. It is lifting caused by fronts.

b. It is lifting caused by mountains.

c. It is lifting caused by convection currents.

d. It is lifting caused by the jet stream.

5. How do cold fronts produce stormy weather?

a. Warm moist air ahead of the front is uplifted as the front passes, causing the moisture to condense and precipitate.

b. Cold air behind the front causes the water vapor to evaporate, producing the storm.

c. The warm air mixes with the cold air along the front, creating low pressure and storms.

d. The cold air holds more water vapor than the warm air, thus it must precipitate out as rain or snow.

6. What is a wave cyclone?

a. It is a type of cold frontal uplift that occurs in waves along a squall line.

b. It is the rise in sea level of the water underneath a hurricane.

c. It is a spiraling storm system at the boundary between the polar air and the warm mid-latitude air.

d. It is the process of storm development over the mountains as air is uplifted by the mountain slopes.

7. What effect has Doppler radar had on weather forecasting?

a. It has helped monitor storms as they approach a region.

b. It has helped track rain droplets, hailstones, and wind patterns within a storm.

c. It has helped monitor thunderstorms, which may create tornados.

d. All of these are true.

8. What benefits have weather satellites provided?

a. They have gathered vast quantities of data which has improved our weather prediction abilities.

b. They have save lives by giving us advanced warning of storms.

c. They have provided data over remote regions of the earth like the poles and tropical jungles.

d. All of these are correct.

9. Which weather event/atmospheric property is not correctly matched with its measuring instrument?

a. wind direction and speed—anemometer and wind vane

b. humidity—manometer

c. air pressure—barometer

d. temperature—thermometer

10. How are weather graphs like those you analyzed in this lesson useful?

a. The graphs show patterns that may not be apparent in the numerical data.

b. The graphs track rain droplets, hailstones, and wind patterns within a storm.

c. The graphs are used to monitor thunderstorms, which may create tornados.

d. They are useful to predict changes in the Coriolis effect.

11. When is the relative humidity usually the highest?

a. in the early morning

b. in the late afternoon

c. during noontime

d. just after sunset

12. What is the relationship between low pressure and precipitation?

a. Precipitation usually occurs at times of low pressure.

b. Precipitation usually occurs at times of high pressure.

c. Precipitation usually occurs at times of stable pressure.

d. Precipitation occurs at any time; there is no relationship.

13. Which is not a myth of tornados?

a. Areas near mountains or bodies of water are safe from tornados.

b. Tornados usually occur in the spring but can happen during any season.
c. The low pressure in the funnel cloud can cause buildings to explode.

d. Opening windows during a storm is a good idea.

14. Which statement is not a safety rule when faced with an approaching thunderstorm?

a. Find a safe place to go; a basement or interior room without windows is best.

b. Know the geography of your home county including place names and directions.

c. Check the weather forecast before planning a trip or outdoor activity, especially in the spring and summer months.

d. Large rooms like a gymnasium or church meeting hall are best during a severe storm.
