Areas along coastlines, such as Florida, often do not experience winters as severe as areas inland – even though some of these coastal areas lie further north.
Why do coastal areas tend to have more mild winter weather patterns?
Warm ocean waters heat the air above them, the warm air flows over coastal areas, but cannot reach areas inland.
Cold ocean waters cool the air above them, the cool air flows over coastal areas, but cannot reach the areas inland.
Warm ocean currents only flow east to west and cannot reach inland areas.
Cold ocean currents only flow east to west and cannot reach inland areas.
Amy and Scott are preparing a presentation on climate in Florida.
Which of the following statements would BEST support the idea that Florida has a subtropical climate?
Florida has a long pattern of experiencing hot, humid summers and mild to cool winters.
Florida’s location near the equator makes it cooler than most of the United States.
Florida received 35 inches of rain this past year.
Florida had record high temperatures this past summer.
Humid weather occurs most often during warm, summer months. Why are the summer months more humid?
Warm air holds more water vapor than cold air.
Cold air rises quickly into the atmosphere.
Air holds ice in the winter and water vapor in the summer.
Water is only present in the air during the summer.
The surface of the oceans are warmer than deeper ocean waters.
Which of these is a direct result of uneven heating of water in the oceans due to solar energy?
ocean currents
salt in the ocean
icebergs in the ocean
ocean tides
Solar energy does not warm Earth’s surface evenly. For example, during the day, land areas warm up faster than nearby bodies of water.
How does this uneven warming affect the movement of air over land and water?
The warmer, less dense air above the land flows toward the cooler, denser air above the water, causing a land breeze.
The cooler, denser air above the water flows toward the warmer, less dense air above the land, causing a sea breeze.
The cooler air over the water would absorb water vapor and rise, resulting in rainy conditions over the shoreline.
The warmer air over the land would transfer energy to the cooler air by conduction, leading to a uniform air temperature.
The graphs below show the average temperature range and average precipitation in Denver, Colorado.
Using the information from both graphs, what is one true statement that can be made about Denver’s climate?
The winters are cooler and drier than the summers.
The warmest month is February
The temperature and precipitation do not change over the year.
The month with the greatest precipitation is October.
During a summer day on the beach, the sand on the beach and the air temperature feel hot, but the ocean water feels cold.
At night, why would the ocean water be warmer than the air?
Air changes temperature faster than water, so the water is warmer and the air is much cooler than it was during the day.
As a cool breeze blows off the water onto the land, the water warms up.
The heat from the air transfers to the water during the night, making the water warmer than it was during the day.
Air stays warmer longer than water so your body is warm when you jump into the water.
El Niño is a weather event that causes great changes in weather worldwide. During an El Niño event, the polar jet stream shifts northward.
Which change will an El Niño event most likely cause?
warmer than usual temperatures in the northern United States
colder temperatures in the southern United States
drier than usual weather in the northern United States
drier than usual weather in the southern United States
Adding or removing heat from a system may result in a temperature change. Ben found a penny outside on the hot sidewalk. He brought it inside and added it to a cup of room temperature water.
What will happen to the penny’s temperature once he puts it in the cup of water?
the heat will transfer from the penny to the water
the heat will transfer from the water to the penny
the penny will not change temperature
the penny will change state
Jonathan performed an experiment using a heating lamp, a cup of water (A), an empty cup (B), and two thermometers as shown in the illustration below. After 40 minutes he observed the temperature inside each cup.
Based on the illustration above, what do you think Jonathan observed at the end of his experiment?
The temperature measured in Cup A is lower than Cup B.
The temperature measured in Cup A is higher than Cup B.
The temperatures in Cup A and Cup B are the same.
The temperatures in Cup A and Cup B did not change.
The transfer of energy as heat occurs all around us. When a warmer stream flows into a cooler lake, which of the following happens?
The stream water transfers heat to the lake water.
The stream water absorbs cold from the lake water.
The lake water transfers heat to the stream water.
The lake water absorbs cold from the stream water.
A large piece of a glacier broke off into the ocean.
Which of the following actions would you predict will occur to the ocean water?
Heat will flow from the water to the ice.
Heat will flow from the ice to the water.
Cold will flow from the water to the ice.
Cold will flow from the ice to the water.
Mandy is investigating migration. She thinks that birds instinctively fly south for the winter and hypothesizes that they do so because they cannot survive in cold weather.
Which of the following could serve as empirical evidence to support her hypothesis?
charts displaying birds’ migratory patterns in relation to weather
feelings based on her own reactions to winter weather
data from another scientist’s experiment on bird anatomy
inferences made about the birds based on observations of flocks of flying geese
Unprotected exposure to the sun’s rays is a factor in the development of skin cancer.
Which of the following is an example of empirical evidence that supports this hypothesis?
data demonstrating a relationship between amount of sun exposure and incidences of skin cancer
an advertisement for a sun block product that claims it protects skin for ultraviolet rays
a model of a skin cell showing where DNA is in the cell
a skin cancer survivor’s recollection that he had a bad sunburn as a child
Air masses that form over large bodies of water are moist.
What process determines the amount of moisture in an air mass?
Evaporation
Condensation
Precipitation
Runoff
Airplane flight paths often take advantage of the jet stream.
What are jet streams?
narrow bands of strong winds high in the atmosphere
steady, warm breezes
large air masses that flow over Earth’s surface
cold, moist air sinking in the atmosphere
A model can represent an object, system, or process.
Why do all models have limitations?
because a model is never exactly the same as the thing it represents
because all models are two-dimensional
because a model includes every factor that affects it
because a model is smaller than the thing it represents
On any given day, the weather forecast might say that rain, snow, and sleet are expected.
Which of the following statements is describing this area’s climate?
Rain, snow and sleet are common during the month of December.
Sleet is a combination of rain and snow.
Last January it snowed for 17 days in a row.
The rain turned to sleet and snow later that afternoon.
In some parts of the world, yearly flooding is expected. Floods also occur unexpectedly during severe weather and can cause great damage.
What changes in the water cycle would MOST LIKELY result in severe flooding?
increased precipitation and increased runoff
decreased evaporation and decreased condensation
increased evaporation and increased condensation
decreased precipitation and decreased runoff

Roberto does a study comparing how plant growth is affected by sunlight. He shares the following chart with his classmate Ava. Ava is trying to follow the accepted practices of the scientific community, so she asks Roberto to document his research methods.
Which BEST explains why this is an important step?
because Ava and Roberto’s peers will want to repeat his experiment and confirm his results before they accept his explanation
because it is not clear from the chart alone whether Roberto used the same type of plant
because scientists are often dishonest about their results and it’s important to make sure that Roberto is telling the truth
because Ava is curious and may have a better way of doing the experiment
