Why are lower, smaller sand dunes less desirable than higher, larger sand dunes?

Why are lower, smaller sand dunes less desirable than higher, larger sand dunes?
   a. Lower dunes promote more erosion because there is not as much dune sand to absorb wave energy.
   b. Lower dunes cannot prevent waves washing over the dunes to strike the homes.
   c. Lower dunes promote the formation of riptides.
   d. Lower dunes block the wind in unnatural ways, causing more damage to surrounding homes.
   e. Lower dunes are difficult to naturally revegetate.

Question 2

How does faster forward speed of a hurricane affect coastal areas?
   a. higher-level surge and more rain
   b. higher-level surge and less rain
   c. lower-level surge and more rain
   d. lower-level surge and less rain
   e. more wind damage

Question 3

Which roofing design is the most hurricane-resistant?
   a. sloped, clay tile
   b. flat, wood shingle
   c. flat, metal
   d. flat, concrete tile
   e. sloped, stucco

Question 4

Which factor does NOT contribute to increased height of a storm surge?
   a. low atmospheric pressure
   b. strong hurricane winds
   c. fetch
   d. shallow water
   e. deep water

Question 5

When do most hurricanes develop (which months), and why?
   a. July, because that is the hottest month and rainfall is highest in the tropics
   b. July, because winds are the highest over the normally stagnant doldrums of the equatorial ocean
   c. July and August, because those are the hottest months
   d. August and September, because it takes all summer to warm the ocean
   e. November and December, because it takes all year to warm the ocean

Question 6

Where in a hurricane is the atmospheric pressure lowest, and approximately what is that pressure?
   a. lowest in the zone of high winds, just outside the eye; about 950 millibars
   b. lowest just outside the eye wall; about 920 millibars
   c. lowest in the eye; about 960-970 millibars
   d. lowest in the eye; about 1200-1300 millibars
   e. lowest in the zone of high winds, midway between the eye and its outer fringes; about 900-910 millibars

Question 7

Where do hurricanes striking North America originate?
   a. the central Pacific Ocean, near the equator
   b. in the Gulf of Mexico
   c. off the northern coast of South America, near the equator
   d. waters in near-equatorial latitudes off the west coast of Africa
   e. in the steamy jungles of the Congo, in western Africa

Question 8

Where does a tropical cyclone or hurricane get its energy?
   a. in the heat and moisture rising from a low-pressure cell of the tropical ocean
   b. from heat of the sun shining off a hot desert near the equator
   c. from high temperatures of a humid high-pressure weather cell near the equator
   d. from high summer temperatures over humid equatorial jungles
   e. in the dry, cool air coming from a low-pressure cell of an adjacent ocean
