Answer 1

1. Solar energy from the sun
2. Uneven heating of the Earth
3. Areas of high and low pressure are created
4. Global winds are created
5. Wind creates surface currents

a. Ocean currents
b. The Coriolis Effect
c. The uneven heating of the Earth
d. The movement of areas high and low pressure

Answer 2

c. The uneven heating of the Earth

Question 3

Answer 3

high-pressure, low pressure

Question 4

b. Deep Ocean Currents
c. Riptides
d. Surface Currents

Answer 5

Surface Currents

Question 6

Deep ocean currents are affected by differences in ________, which is determined by the waters’ temperature and __________ level

Answer 6

density, salinity

Question 7

What type of weather is associated with Low pressure?

What type of weather is associated with High pressure?

Answer 7

Low Pressure: Lousy weather, humidity, light precipitation, warm temperatures

High pressure: Sunny skies, cool temps, no clouds

Question 8

When warm air rises, an area of low pressure is formed. When cool air falls, an area of high pressure is formed. True or False: “The barometric pressure of an area of high pressure is greater than the barometric pressure of an area of low pressure.”

Answer 8

True

Question 9

Which kind of pressure is associated with humidity?

Answer 9

Low pressure

Question 10

What is the difference between weather and climate?

Answer 10

Weather is a condition of the atmosphere in one place during a short period of time while climate is weather patterns typical for an area over a long period of time.

Question 11

What kind of weather should you expect after a cold front passes through?

Answer 11

Sunny skies, cold temps

Question 12

Pt 1. Name two conditions that will cause a hurricane to lose strength?

Answer 12

Pt 1. Move over cooler water, Move over land

Question 13

What causes hurricanes to rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere?

Answer 13

Coriolis Effect (caused by the rotation of Earth on its axis)

Question 14

What kind of weather should you expect after a cold front passes through?

Answer 14

Clear and cool weather once the front passes (High and dry not a cloud in the sky)

Question 15

Pt2. What factors contribute to the formation of hurricanes?

Answer 15

2nd part: Tropical winds, Warm water, Warm air
