Question 5 - What is a storm surge?
A dome of seawater formed rising above sea level that floods the land during a hurricane.
It refers to intensifying winds combining to reach maximum speed.
The combination of a high tide and a cyclone.
When a hurricane makes landfall.
Question 6 - Oceanographers have determined that sea level has
risen close to 200 cm over the past century.
lowered about 2 cm over the past century
risen about 17 cm over the past century.
remained at the same level for the past century.
Question 7 - Which of the following are depositional features along the shoreline?
sea stacks and spits
sea stacks and bayrnouth bars
spit and barrier island
barrier island and wave-cut terrace
wave-cut terrace and sea arches
Question 8 - In mapping the topography of the ocean floor,
sonar uses light waves to map ocean surface elevation.
satellites use sound waves to enable us to map the seafloor by determining the depth of the ocean.
our knowledge of the seafloor is complete; there are no regions we have not mapped.
deep seafloor research involves drilling, permanent observatories, sonar, ROV's and manned sumbersibles.
Question 9 - Which of the following is the best way to preserve a beach?
Build seawalls to prevent the longshore current from carrying the sand away.
Build groins every 10 meters or so.
Build breakwaters to prevent waves from removing its sand.
Leave it alone, building no groins, seawalls, breakwaters on or near them.
Question 10 - As oceanic crust spreads farther and farther from the ridge:
it accumulates more and more sediments.
it keeps the same amount of sediments.
it is swept clear of sediments.
it accumulates more and more volcanic materials.
Question 11 - Submarine canyons are formed primarily by:
glaciers when sea level was much lower.
rivers when sea level was much lower.
turbidity currents eroding the edge of the continental shelf and slope.
faulted rift valleys
Question 12 - What causes the highest (and lowest) tides to take place every two weeks?
The Sun and Moon are positioned in line with each other with respect to Earth.
Variations in Earth's orbit causes an increase in the gravitational force of the Sun.
The Sun and Moon are positioned at right angles to each other with respect to Earth.
The gravitational force of the Moon is parallel to prevailing wind directions.
Question 13 - What process causes temperature to increase and pressure to decrease as a hurricane forms?
Energy from the sun warms the air and causes low pressure to form.
Water evaporates, cooling air in the vicinity of the developing storm.
Excessive wind speeds creates the low pressure center.
Water condenses, heating air in the vicinity of the developing storm.
Question 14 - How can human activity such as construction of a jetty or groin extending at right angles out into the ocean cause a beach to be altered?
The jetty can reverse the direction of the longshore currents.
The construction of a jetty or groin does not alter the beach.
This usually causes much sand to be eroded away from both sides of the structure.
The jetty prevents input of sand on one side, and part of the beach is removed by erosion.
Question 15 - Longshore currents (choose 3 that correctly apply
are caused mainly by the interaction between the sun and moon.
are erosional and also depositional agents.
have nothing to do with the formation of rip currents.
are shallow currents flowing parallel to shore.
are deep currents flowing perpendicular to shore.
are generated by a combination of swash and backwash.
Question 16 - Which of the following characterizes the West Coast of the United States? (Choose 3 answers)
This is considered a passive margin.
There are subduction zones present.
This is considered an active margin.
There aren't subduction zones close by.
There aren't trenches close by.
There are trenches off shore.
Question 17 - Which of the following characterizes the East Coast of the United States? (choose 3)
There are subduction zones near the continent.
There are no trenches adjacent to the continent.
It is considered a passive margin.
There are trenches present.
There are no subduction zones nearby.
It is considered an active margin.
Question 18 - Waves carry _____ from one place to another often far away place, and the water itself ________.
Water/can move many miles together with the wave.
Energy/moves right along with the waves.
energy/moves in a circle staying basically where it is.
water/loses energy as it travels.
Question 19 - Why are abyssal plains so flat?
Because the volcanic lava flattens as it spreads out.
Because of years of accumulating sediments.
Because of the mid-ocean ridges steadily diverging apart.
Because of the water continuously eroding it away.
Question 20 - What are neap tides? (Choose TWO answers)
Tides that are the result of the sun and moon attracting Earth's water in directions at a right angle to each other.
Tides that result from hurricanes.
Tides that are caused by the sun and moon being in alignment with the Earth.
The tides each month that have the least displacement.
The tides each month that have maximum displacement.
Question 21 - Which of the following is correct regarding hurricanes? (Choose 3)
they form over warm tropical waters.
typically form during the months of May through August.
A storm with 145 miles/hour winds and a storm surge of 4 meters would be a category 4 hurricane.
occur most commonly in the South Pacific.
The deadliest natural disaster of our time was a cyclone that killed 1/2 a million people in Bangladesh in 1970.
A storm with 165 miles/hour winds and a storm surge of 5 meters would be a category 3 hurricane.
The deadliest natural disaster of our time was Hurricane Katrina.
