A hurricane is a large, rotating storm system that forms over water, bringing high winds, rough seas, and heavy rain. Hurricanes occur where —
the ocean has extremely high tides.
ocean water is the coolest, near the pole in the late winter.
ocean water is the warmest, near the equator in the late summer.
the ocean has extremely low tides.
During an El Niño weather event, trade winds across the Pacific Ocean weaken, and waters along the coast of Peru and Ecuador become unusually warm. The warmer ocean waters result in —
the formation of numerous thunderstorms along the South American coast.
many days of clear, cold weather along the South American coast.
many days of clear, warm weather along the South American coast.
the formation of numerous hurricanes along the South American coast.
La Niña is a weather event that can cause floods and droughts in different parts of the world. La Niña usually begins with a cooling of the —
soil in North America.
mountains in South America.
sea ice in Antarctica.
tropical eastern Pacific Ocean.
Tropical depressions tend to originate over —
sandy deserts, where water is likely to rise as vapor and remain in the air as clouds.
sea ice, where water is likely to rise as vapor and later fall as snow.
large lakes, where water is likely to rise as vapor and remain in the air as fog.
warm oceans, where water is likely to rise as vapor and later fall as rain.
Changes in ocean temperature affect weather because they influence interactions between the —
land and air at the edges of the ocean.
air and water at the bottom of the ocean.
air and water at the surface of the ocean.
land and water at the bottom of the ocean
The ocean most affected by the El Niño weather event is the ______ Ocean.
Arctic
India
Atlantic
Pacific
During the time period that an El Niño is occurring —
The food supply for fish in the region is increased.
There is a buildup of warm water off the coast of South America.
The trade winds get stronger and cause a cooling of the surface water of the ocean.
The normal weather does not change very much.
What is the main obstacle that fish moving from freshwater to marine environments must deal with?
Sand on the floor
Wind
The salinity of the water
Ship traffic
A scientist learns about two currents in an ocean. Arrows on the map show these currents.
Information in the map will MOST help people to —
Predict storms
Build faster boats
Prevent hurricanes
Stop water pollution
A scientist learns about ocean currents between two islands. Arrows on the map show these currents.
What this scientist learned will MOST help people understand why the two islands have different —
Animals
Coastlines
Mountains
Temperatures
Two students are studying a map of the United States that shows July temperatures averaged over a ten-year period. One notices that cities on the East Coast have warmer temperatures than cities at similar latitudes on the West Coast. Which of the following is responsible for the difference?
El Niño brings rain and cool weather to the West Coast but does not affect the East Coast as much.
The Pacific Ocean is larger and deeper than the Atlantic Ocean and is, therefore, colder than the Atlantic Ocean.
Ocean currents from the Tropical Atlantic warm the East Coast, while currents from the Northern Pacific cool the West Coast.
During the summer, the East Coast is often hit by hurricanes, which bring warm air as they move along the coast.
During the climatic phenomenon, El Niño, surface seawater temperatures off the west coast of South America are higher than normal. This tends to increase rainfall in the western parts of North and South America because warm water —
precipitates more easily than cool water
evaporates at a higher rate than cool water
absorbs more heat energy than cool water
condenses at lower altitudes than cool water
Ocean currents move warm and cold water throughout the oceans, affecting weather systems and climates. Where do warm ocean currents originate?
near the poles
near the equator
near continents
near the middle of oceans
A student uses this diagram to understand the parts of a fish. The student then uses an identification key to classify different types of fish.
Based on the key, which of these fish is most likely a bluegill?
The textbox contains information about salmon.
How do populations of juvenile salmon respond to changes in salinity as they migrate?
The juvenile salmon alter their behavior but do not utilize special structures.
The juvenile salmon alter their behavior and utilize special structures.
The juvenile salmon utilize special structures but do not alter their behavior.
The juvenile salmon utilize special structures to alter their behavior.
What structure is an adaptation for fish that enable the fish to breath by extracting dissolved oxygen from the water?
gills
fins
scales
mucus layer
Fish have an organ called a swim bladder. The pictures show the swim bladder in use by a fish. What function does the swim bladder provide for the fish?
It allows the fish the ability to see in deeper waters.
It allows for the fish to scare off predators by increasing its size.
It allows for extra storage of food for the fish.
It allows the fish to vary its buoyancy in the water.
Scientists use this tool to identify organisms by their physical characteristics—
anemometer
cladogram
dichotomous key
topographical map
Animals that live in estuaries-
tend to produce few offspring.
are usually found in unpolluted environments.
must be adapted to varying levels of salinity.
are adapted to cold-water conditions.
The types of organisms found in a pond or lake depend on
the amount of sunlight available
the temperature of the water
the presence of nutrients
all of the above
Which of the following statements is NOT correct?
Lakes may contain a region that receives little sunlight
Wetlands help remove pollutants from water
Swamps are dominated by woody shrubs and water-loving trees
Rivers generally move faster, and their oxygen levels decrease, as they near the ocean
