An example of this has been in the Pacific Ocean where scientists have observed colder temperatures than average and increased rainfall. This has been the result of what phenomenon?
El Niño
La Niña
melting glaciers at the poles
thermohaline circulation
Which of the following is not caused by the ocean’s increased absorption of heat from the atmosphere?
coral bleaching
ice caps melting
increased oxygen
sea water expansion
What property of water enables oceans to have a significant influence on climate by absorbing and storing heat energy?
high heat capacity

low thermoclines
high thermoclines
When traveling from the coast of Florida to an inland city such as Orlando during hot summer months, temperatures tend to be higher inland than at coastal beaches in the region. What accurately describes why this is the case?
Land temperatures tend not to fluctuate.
Land closer to coastlines will retain heat.
Water reflects heat warming up land farther away.
The ocean water absorbs heat which keeps the coastal areas cooler.
According to the South Florida Water Management District, Florida’s climate has a wet and a dry season. In any year, a drought can take place during the wet season. Which of the following is a true statement about the impact of droughts?
Droughts have no impact on Florida ecosystems.
Droughts improve the quality of soil and landscape conditions.
Droughts affect the water consumption needs of all types of organisms.
Droughts exist in areas where the amount of precipitation is above normal.
Oceans are natural carbon sinks, capable of absorbing at least a quarter of atmospheric carbon. For many years, the atmospheric levels of carbon was lower than the emission levels because of the capture of carbon in the oceans. However, the oceans may be reaching the limit of carbon they can hold. In 2009, a study showed that the southern Indian Ocean was less effective at absorbing atmospheric carbon than it had been previously. Eventually, the oceans will be unable to absorb and hold any additional carbon. What is the most likely consequence for atmospheric carbon dioxide levels if the oceans become unable to absorb and hold additional carbon?
Atmospheric carbon dioxide levels will increase dramatically.
Atmospheric carbon dioxide levels will decrease dramatically.
Atmospheric carbon dioxide levels will rise slowly.
Atmospheric carbon dioxide levels will fall slowly.
Which of these would be the most appropriate human response as a result of this weather alert?
getting into a boat during the storm to prepare for flooding
going outside before the storm to nail boards on house windows
from a tornado
going outside during the storm to avoid being struck by lightning
storm to avoid being struck by lightning
getting into a car before the storm to prepare to drive away from a tornado
Which statement is the most likely reason some people from northern locations move to Florida for a few months each year?
During the spring season, Florida is colder than the northern locations.
During the autumn season, Florida is colder than the northern locations.
During the winter season, Florida is warmer than the northern locations.
During the summer season, Florida is warmer than the northern locations.
A long period of high heat and humidity can have long- and short-term effects on Florida's residents. Which of these is a long-term health risk to Florida residents caused by high heat and humidity?
increased need for hydration
increased mold growth in buildings
increased mold growth in buildings
increased exposure to solar radiation
The Gulf Stream is a strong Atlantic Ocean current that begins at the tip of Florida. The portion that lies off the coast of Florida is called the Florida current. Researchers are working to use the current as a source of renewable energy. How would this research negatively affect Florida?
Aquatic habitats may be disturbed.
Competition with oil companies will increase consumer costs.
Hurricane formation will increase.
Water sports will be limited.
In certain emergency situations, swimmers in waters off the Florida coast are advised to do one of the following: Swim parallel to the shore. Swim at an angle back to shore. *Remain floating until you no longer feel a strong pull.
The above directions are designed as a response to what emergency situation?
flash floods
lightning
rip currents
storm surges

Earth's climate change may be triggered by internal and external conditions. Which of the following would not be considered an external factor that might affect climate change?
the fluctuation of solar radiation
spring flooding after heavy winter snowfall
ability of water to store large amounts of solar heat
volcanic eruptions that send substances into the atmosphere
Surface currents redistribute heat from the equator towards the poles. Why are the climate and waters around the Galapagos much cooler than would be expected, given their proximity to the equator?
There are only cold water currents around the Galapagos.
The warm water cools by the time it reaches the Galapagos.
The current in this area is moving warm water away from the Galapagos.
Heat distribution is uneven and upwelling brings cold water to the surface around the Galapagos.
The Earth's ocean conveyor system helps move water from cold regions to warm tropical regions. Which of the following factors is not a cause of the conveyor system?
carbon dioxide levels
continent size
salinity
surface currents
Which of the following is not a reason that the ocean affects climate?
the high heat capacity of the ocean
the ocean’s ability to produce energy
the large amount of water contained in the ocean
the ocean’s ability to exchange heat with the atmosphere
Even prior to protection by the national government the Florida Everglades were sparsely populated. The density of permanent residents was lower there than in other parts of southern Florida. What is the most probable reason for relatively fewer people living in the Everglades?
seasonal flooding
lack of fresh water
lack of food resources
extreme temperatures
Oceans heat up and release water into the atmosphere as a gas. This helps moderate temperatures. Which of the following is occurring?
condensation
evaporation
precipitation
transpiration
There is a trend among some environmentalists toward heating their homes with wood or wood pellets rather than fossil fuels such as coal, natural gas, or oil. What reason might such people give for using wood rather than fossil fuels?
Burning wood is carbon-neutral.
Wood is less expensive and readily available.
The timber industry employs local workers, and keeps the local economy healthy.
The wood being burned absorbed carbon during its lifetime, and replacement trees will also absorb carbon.
Riptides are dangerous currents that often occur after tropical storms. Florida communities along the coast have put many strategies in place to keep people safe. What is one riptide safety strategy that Florida beach communities avoid?
closing the beaches to all swimmers
teaching people how to swim out of riptides
posting and announcing the presence of riptides
teaching people to recognize riptides in the water
A flash flood is a fast-moving water stream that may occur with little or no warning. In Florida, flash floods are an effect of hurricanes. What is one effect that flash floods have on humans in Florida?
Flash floods increase rock and beach erosion.
hurricanes.
Flash floods provide a safe source of drinking water.
Sometimes surface features change after a flash flood.
Some people move away from coastal areas for fear of hurricanes.
When a tropical storm heads toward Florida, some residents need to evacuate their homes to stay safe from the risks of flooding, damaging winds, and rain. To avoid the risk of evacuation, where should people reside?
bay areas
coastal areas
lower elevations
higher elevations
Earth’s climate can be affected by natural factors such as changes in volcanic activity, solar output, and Earth's orbit around the Sun. Climate change can also be caused by human activities such as the burning of fossil fuels and the conversion of land for forestry and agriculture. The increase of which greenhouse gas due to human activity has had the greatest impact on global climate in the past century?
carbon dioxide
methane
ozone
water vapor
The carbon cycle interacts with the hydrosphere, but carbon is not easily removed from this environment. Therefore, the oceans are often referred to as a carbon sink. What is one way carbon is removed from the ocean?
Carbon is carried by deep ocean currents.
Phytoplankton turns the carbon into organic matter.
skeleton structures.
Organisms use carbon to make calcium carbonate for their skeleton structures.
At the surface, carbon dioxide is exchanged between the ocean and the atmosphere.
