What is evaporation?
Evaporation occurs when liquid water turns from a liquid to a gas called water vapor.

In South Florida there is a rainy season and a dry season. Northern areas of the United States have a normal four-season cycle.
In the northern states it can snow for many months during the winter.
Sometimes the snow can pile up and create very large mounds.
What will happen to most of the snow when spring arrives?
A. The snow will freeze into snowballs and roll down the mound.
B. The snow will melt and runoff into the ground or local water table.
C. The snow will evaporate and create amazing looking clouds.
D. The snow will condense into hail stones and remain on the mound.
B. The snow will melt and runoff into the ground or local water table.
Water runs down creeks and rivers until it flows into the ocean. At what stage in the water cycle does the water return to the creeks and rivers?

c.precipitation
d.vapor formation
c.precipitation
Which of the following best describes what clouds are made of?
a.fog that has risen from the ground
b.large amounts of water that has evaporated
c.water vapor that has condensed into droplets
d.rain or snow that has been pushed together by wind
c.water vapor that has condensed into droplets
Micheala read that without the ocean, the water cycle could not take place. Why is the ocean so important to the water cycle?
a.The ocean provides the heat necessary for evaporation to occur.
b.The ocean is where most of the evaporation process takes place.
c.The salt in the ocean keeps Earth's water from being evaporated.
d.The ocean reflects the rays from the Sun so that not all water is evaporated.
b.The ocean is where most of the evaporation process takes place.
Felicia and Peter were spending a July morning out in the Everglades.
It was extremely hot that day, so they decided to head home early.
On their way home they stopped for lunch at a diner.
When they got back into car to drive home it started to rain very heavily.
What is the best explanation of why it started raining so heavily on their way home after lunch?
A. It always rains near the Everglades because there is so much water.
B. The warm temperatures caused the clouds to evaporate and turn into rain.
C. The hot temperature increased evaporation in the morning which condensed in the clouds and fell as precipitation when the temperature fell in the afternoon.
D. The hot temperature decreased the amount of water vapor in the clouds which caused a heavy rainstorm.
C. The hot temperature increased evaporation in the morning which condensed in the clouds and fell as precipitation when the temperature fell in the afternoon.
Which answer best explains why clouds usually form high in the sky?
a.It is cold enough there for the water vapor to begin condensing
b.It is warm enough there for evaporated water to expand into clouds
.cIt is dry enough there for precipitation to form from condensed water vapor
d.It is windy enough there for water droplets to get pushed together into clouds
a.It is cold enough there for the water vapor to begin condensing
