• Because rates of evaporation and precipitation
  are constantly changing
• Because the direction of the wind over the ocean
  is constantly changing

123

• 4.Why does the ocean cover different amounts of
  the beach at different times of the day?
• Because the moons gravity pulls the ocean,
  causing it to rise and fall
• Because earth wobbles as it rotates, causing the
  ocean to rise and fall
• Because the ocean currents change, adding sand to
  and removing sand from the beach
• Because sand is able to absorb more water as the
  temperature increases, lowering the ocean level

124

• 7. Which of the following describes the relative
  positions of earth, the sun, and the moon when
  the smallest difference between high tide and low
  tide occurs?
• The sun and earth were at right angles to each
  other relative to the moon.
• The sun and moon were at right angles to each
  other relative to earth.
• The sun, moon, and earth were aligned with the
  moon between the sun and the earth.
• The sun, moon and earth were aligned with earth
  between the sun and the moon.

• 8. Karla is gong to search for clams and oysters
  during low tide. If she knows that high tide is
  at 1000am today, at what time should she plan to
  start searching for shellfish?
• 1000pm
• 400 pm
• 1000 am the next day
• 200 pm

128

• 9. Deep currents form when
• Cold air decreases water density
• Warm air increases water density
• The ocean surface freezes and solids from the
  water underneath are removed
• Salinity increases

129

• 10. When waves approach the shore,
• They speed up
• They maintain their speed
• Their wavelength increases
• Their wave height increases

• Intermediate Zone

132

• 2. Which of the following is typical of a
  tropical climate?
• Cold, dry air
• Cool, moist air
• Hot, dry air
• Warm, moist air

133

• 3. If a rock and container of water have the same
  mass and temperature and are exposed to the same
  amount of heat energy, what will MOST likely
  happen?
• The water will transfer the heat to the rock
• The rock will transfer heat to the water
• The temperature of the rock will rise faster
• The temperature of the water will rise faster.

134

• 4. While visiting the beach during a summer
  vacation, a sea breeze keeps you cool and
  comfortable during the hottest part of the day.
  Which BEST explains why this happens?
• Warm air rising over land allows cooler air from
  the ocean to blow inland
• Cool air rising over land allows warm air form
  the ocean to blow inland
• There are similarities in temperature between the
  land and water
• A storm is approaching

135

• 5. Which statement about Earths heating patterns
  is true?
• The rate of cooling depends on the season
• Large bodies of water cool more quickly than land
• Land cools more quickly than large bodies of
  water
• Land and large bodies of water cool at the same
  rate

136

• 6. Which event will occur next in this series of
  meteorological events at an oceanfront town?
• Bright sunny day
• Night falls
• Land and ocean begin to lose stored heat from sun
• One (land or ocean) first reaches a temperature
  that is equal to one of its surrounding
• High pressure front moves in over the land
• Cool land breeze
• Cool sea breeze
• Warm land breeze
• Warm sea breeze

• Cold air masses that form at high latitudes are
  called
• Polar air masses
• Continental air masses
• Warm air masses
• Maritime air masses

139

• 2. Suppose you are swimming in a lake when a
  thunderstorm approaches. Which of the following
  would be the best way to protect yourself from
  lightning?
• Diving underwater
• Going fishing instead of swimming
• Taking shelter in an automobile
• Taking shelter under a tree

140

• 3. Which of these BEST explains the reason that
  thunderstorms are likely to form on a hot day?
• Warm, humid air rises quickly and then cools
• As air slowly rises it loses humidity and causes
  rain
• The air is usually calm and allows the clouds to
  form
• The air rises quickly and forms low-level cloud
  layers

141

• 4. Warm air rising at the equator and cold air
  sinking at the poles is one reason for which
  event?
• Hurricanes
• Coriolis force
• Earths rotation
• Convection currents

142

• 5. Jennifer measured the temperature difference
  between two areas located next to each other.
  She did this at four locations. Which location
  is MOST LIKELY to have the strongest winds?
• Lake and river
• Forest and field
• Pond and stream
• Ocean and beach

143

• 6. In some years there are more hurricanes than
  usual. This is probably because
• The ocean is warmer than usual
• The ozone layer is very thin
• There are more windy days than usual
• The gravitation pull of the moon is stronger

144

• 7. At the seashore late in the afternoon on a
  hot, sunny day, a person often feels a strong
