Precipitaion
What process must happen to invisible water vapor in the air for a visible cloud to form?
Condensation
How do plants slow down runoff
Some goes into the soil and feeds plants
After a rainstorm, a puddle on the sidewalk slowly gets smaller and eventually disappears. Where does the water go?
it evaporates into water vapor
What is condensation
When gas turns into a liquid
In the water cycle, what best describes surface runoff?
Why do water droplets and ice crystals in a cloud eventually fall toward the Earth as precipitation?
As droplets merge and grow heavier, the upward air currents can no longer hold them up.
What is the main driving force that causes surface runoff to flow downhill across the land?
Gravity
During the process of evaporation, which changes of state are taking place?
Liquid to gas
How does condensation play a major role in the water cycle?
How does an impermeable surface, such as an asphalt parking lot, affect surface runoff compared to a natural grassy field?
Which step of the water cycle is primarily responsible for returning water from the atmosphere back down to Earth's surface in various forms like rain, snow, or sleet?
Precipitation
What is surface runoff in the water cycle?
runoff is excess precipitation that travels over the landscape into streams, rivers, and eventually oceans.
What best describes the process of evaporation?
A liquid turning into a gas at it's boiling point
During the process of condensation, do water molecules gain or lose thermal energy (heat)?
They lose energy as they cool down

What are the four forms of precipitation
rain, sleet, snow, hail.
Which of the following surfaces is considered impermeable, meaning water cannot soak through it easily?
Pavment/concrete.
Why do wet clothes dry much faster on a hot, sunny summer day than on a cold, cloudy winter day?
In what state of matter is water before it undergoes condensation?
Gas (water vapor)
You take a cold can of soda out of the refrigerator on a warm day, and soon water droplets appear on the outside of the can. Where do these droplets come from?
invisible water vapor in the surrounding air, causing it to condense into visible liquid drops.
What tiny particles floating in the atmosphere do water vapor molecules often condense around to help form cloud droplets
Dust, smoke, and salt particals
How does a steep hill affect the speed of surface runoff during a rainstorm compared to flat land?
The water moves faster and creates more runoff
On a windy day, puddles dry up much faster than on a completely calm, still day. What is the role of the wind?
The wind sweeps away water vapor from above the surface, making room for more water to evaporate.
What happens to water during the process of condensation?
gas turns into a liquid.
What role do microscopic particles like dust, smoke, and salt crystals play in the formation of precipitation?
