Which of the following best explains why waves in the ocean are larger than waves on a small lake?

different amounts of water in them

received different amounts of energy in the fetch

hit the bottom at different angles

are uniform if they are from

Question 7

Surface currents are created by wind and the Earth's rotation. What creates deep water currents?

increase in temperature and decrease in salinity

decrease in temperature and increase in salinity

Increase in temperature and increase in salinity

decrease in temperature and decrease in salinity

Question 8

The following diagram shows a _________________ tide.



spring

neap

normal

diurnal

Question 9

Emperor penguins lay their eggs during the coldest months of the year in Antarctica. This is an advantage for the species because

there are virtually no predators of the penguin during this time of year

they are able to better control their body temperature during the colder months

they are able to huddle together to protect each other's eggs from the cold

the chicks hatch and learn to regulate their body temperature quickly due to the cold

Question 10

On the following diagram what part of a wave is shown by letter B?



wavelength

trough

crest

fetch

Question 11

Predatory fish that swim in the water column, usually have what kind of coloration?

disruptive

counter shading

cryptic

fusiform

Question 12

Which of the following is true about the Mangrove ecosystem?

provide little shelter to organisms but act as a buffer to storm surge

have a high level of plant and animal diversity but erode easily during a storm

provide a habitat to 75% of commercially fished species during some phase of their development

act as a buffer to storm surge but have a low level of plant and animal diversity

Question 13
What is a spring tide?

seasonal tides that occur from March to May in the US and often flood the areas in the Gulf Coast

higher than average high tides and lower than average low tides that occur during the new moon and full moon

lower than average high tides and higher than average low tides that occur during the new moon and full moon

tides that occur during only March and produce lower than normal high tides

Question 14

Deep water currents are caused by ______________________

wind

Earth's rotation

animal movement

changes in salinity

Question 15

Which of the following factors in an estuary is impacted the most by the daily tides?

water temperature

Question 16

Which of the following change in sea surface temperature best describes a La Nina event?

waters in the eastern Pacific show no change in temperature

Waters in the eastern Pacific fluctuate daily in temperature

Question 17 (Multiple Choice Worth 5 points)

Question 22 (Multiple Choice Worth 5 points)

Whales in the order Odontoceti are smaller than whales in order Mysteceti. Which of the following best explains this?

whales in order Mysteceti are filter feeders and obtain lower levels of energy by consuming krill, zooplankton, and small fish.

whales in order Mysteceti are toothed and therefore are high level predators and obtain higher levels of energy by consuming large fish, squid, and seals.

whales in order Odontoceti are filter feeders and obtain higher levels of energy by consuming krill, zooplankton, and small fish.

whales in order Odonto
