National Parks

.Which of the following is an indicator of climate change?

• Decreasing precipitation levels causing hurricanes to form and raise sea levels.

• Increasing in precipitation levels causing hurricanes to form and raise sea levels

• Increases in sea levels causing polar bears to get stuck on ice

• Increase in atmospheric heat causing the melting of ice caps which cause sea levels to raise.

The oceans influence climate in many ways. Which of the following describes one way that oceans influence changes in climate?

• The oceans absorb a large amount of carbon, taking it out of the atmosphere

• The oceans release heat, causing cities to have increased temperatures

• The oceans stores heat until it is needed by plants

• The oceans collect water and release it to fresh water ponds, rivers, and lakes.

Scientists are studying sediment samples from the oceans to understand changes in ocean temperatures throughout the last 6,000 years. This study is employing:

• Direct measurements of changes in temperature

• Indirect measurements of changes in temperature

• Proxy indicators of change in temperature

• Models of oceans sediments to determine temperature

A team of scientists have recorded the air temperature at a ranger station in Blue Springs State Park for the last 10 years. This type of data collection is called:

• Direct measurements

• Indirect measurements

• Models

• Proxy indicators

There are many causes of global climate change. Which of the following creates negative climate change?

• The increase in the use of solar power which raises atmospheric heat

• The increase in greenhouse gases which increase global temp

• The increase in hydro-electric power which pollute oceans

• The increase of nuclear power which increases the amount of atmospheric temp.

Which of the following in NOT a factor that determines climate?

• Latitude

• moon phases

• Oceanic circulation

• volcanic activity

Red tide is an over production of algae in waterways. These algae produce toxins that are released into the water, killing fish and other aquatic life. What is likely a result of an outbreak of red tide along the shoreline?

• People will wear more clothing when going to the beach

• People will wear less clothing when going to the beach

• Fishermen will increase fishing to catch fish before they die

• Fishermen will decrease fishing because fish are infected with toxin

Various atmospheric conditions in Florida have influenced human behavior. Ozone depletion increases UV exposure which can lead to cancer. Which of the following changes in human behavior can we expect to see more of in Florida as time goes by?

• More people wearing face masks to protect from toxins

• More people using wetsuits to keep warm in the winter

• More people wearing flip flops to the beach to keep their feet safe

• More people using sunscreen to protect themselves from the sun

Which practice provides the best means of protecting air and water quality in the wild future generations?

• Driving vehicles with reduced carbon emissions

• initiating recycling programs in neighborhoods

• protecting wildlife areas

• dumping pollutants father from water

13. Most lake ecosystems remain relatively neutral. A chart developed by the Environmental Protection Agency (EPA) indicating the average range of pH levels tolerated by some common lake ecosystem animals is shown in the graph.

pH TOLERANCE LEVELS OF LAKE ANIMALS

The pH of water is 7.0 Which of these organisms should environmentalists observe to obtain the earliest indication of the effects of acid rain on the lake ecosystem?

• perch and frogs

• clams and frogs

• clams and snails

• Mayfly and crayfish
