WATER CYCLE
Liquid water changes into water vapor. What process happened?
What is evaporation?
"It is raining today."
Weather or climate?
What is weather?
Coal, oil, and natural gas are examples of what?
What are fossil fuels?
Under the Sun I heat up slower and cool down slower than land or air. What am I?
What is Water?
Complete the memory clue:
Independent = what I ________.
What is Change
Water vapor cools and changes into tiny liquid droplets. What process is this?
What is condensation?
"Florida summers are usually hot and humid."
Weather or climate?
What is climate?
Burning fossil fuels releases this gas into Earth's atmosphere.
What is carbon dioxide (CO₂)?
Riddle me this: Sunny Skies Send Water High
What is Evaporation
Complete the memory clue:
Dependent = what I ________.
What is Measure
Water droplets in a cloud join together and become heavy enough for gravity to pull them toward the ground. What process happens next?
What is precipitation?
Which would give scientists the BEST information about an area's climate?
A. Today's temperature
B. One week of rainfall
C. One month of humidity
D. Average temperatures collected for 30 years
D. Average temperatures collected for 30 years.
What is deforestation?
A. Planting more trees
B. Removing many trees
C. Cleaning wastewater
D. Water entering an aquifer
B. Removing many trees.
A lamp shines equally on containers of sand and water. Which container's temperature should rise faster?
The sand container.
A student records rainfall every day without changing anything.
Is this an experiment?
No. It is an investigation because the student is recording observations without deliberately changing a variable.
Why is Florida's air often humid?
A. Florida has lots of mountains
B. Warm ocean water evaporates and adds water vapor to the air
C. Florida's rivers freeze
D. Clouds push water into the air
B. Warm ocean water evaporates and adds water vapor to the air.
A city has an unusually cold day in July. Does that one day prove the city's climate has changed?
No. Climate is based on long-term patterns over many years, not one unusual day.
Severe deforestation can damage land and make it dry and desert-like. What is this process called?
What is desertification?
In the sand-and-water experiment, what is the independent variable?
A. Temperature change
B. Type of material
C. Amount of heat
D. Thermometer
B. Type of material, sand or water.
A student changes the type of soil and measures how quickly water drains through each soil.
What is the independent variable?
Soil type.
Put these events in the correct order:
2 → 3 → 4 → 1
Evaporation → cooling → condensation/droplet growth → precipitation.
A scientist wants to determine whether a region normally has hot summers. Which evidence is stronger?
A: Temperatures from yesterday
B: Long-term average temperatures
Explain why.
B. Long-term average temperatures, because climate describes usual weather patterns over many years.
A community begins using cleaned wastewater to water grass and landscaping. How can this help conserve groundwater?
Reclaimed water reduces the amount of groundwater that needs to be used.
In the same experiment, students record how much the temperature changes.
What is the dependent variable?
The change in temperature, because that is what the students measure.
Students cover one container to model cloud cover but leave another container uncovered. They measure the temperature of both.
Why is this an experiment?
Because students change one variable, the cover, and measure its effect on temperature.
