The Water Cycle
This process, responsible for most of the water entering Earth’s atmosphere, is powered almost entirely by the Sun.
Evaporation
The troposphere is ________ the higher you go.
colder
A measure of how hot or cold something is
Temperature
Which condition is MOST necessary for clouds to form? A. Strong winds
B. High temperatures
C. Cooling air
D. Low humidity
C. Cooling Air
What is the main energy source that drives weather on Earth?
A. Earth’s core
B. The Moon
C. The Sun
D. Ocean currents
C. The Sun
Clouds form during this stage of the water cycle when water vapor cools and turns back into liquid droplets.
condensation
Energy transfers from warm air to cold air until their temperatures become_________________.
Equal
the process by which a liquid changes into a gas
evaporation
Fog is essentially which of the following?
A. Clouds that form underground
B. Clouds at ground level
C. Clouds made only of ice
D. Clouds formed by pollution
B. Clouds at ground level
Which type of front often brings thunderstorms?
A. Warm front
B. Cold front
C. Stationary front
D. Occluded front
B. Cold Front
Rain, snow, sleet, and hail are all examples of this part of the water cycle.
precipitation
What is an important cause of rainfall?
Cooling
Conditions such as rain, clouds and wind at a particular time and place
Weather
Explain what happened during the Great Flood of 1862.
The winter was warmer than normal which let to more evaporation to take place. The air parcel rose higher into the troposphere than the cooler air parcels that caused normal rain storms.
What tool measures air pressure?
A. Thermometer
B. Anemometer
C. Barometer
D. Hygrometer
C. Barometer
This process releases water vapor from plants into the air.
A) condensation
B) transpiration
C) advection
D) deposition
B) transpiration
The warmer an air parcel is, the ________ it will rise into the troposphere.
Higher
Something we observe to be similar over and over again
Pattern
A. Stratus
B. Cumulonimbus
C. Wispy
D. Nimbostratus
C. Wispy
When air sinks in a high‑pressure system, the weather is usually:
A. Stormy
B. Cloudy
C. Calm and clear
D. Windy and rainy
C. Calm and clear
What keeps the process of water moving downward?
Gravity
When the ______ has lost enough energy and become ____ enough, water vapor in the parcel condenses, forming a cloud.
air parcel, cold
To move from one object to another or one place to another
Transfer
Explain why all clouds do not produce rain.
Clouds produce rain when tiny droplets of liquid water began to stick together, forming larger and larger drops. The conditions have to be right from those processes to take place
Which cloud type is most associated with thunderstorms?
A. Cirrus
B. Stratus
C. Cumulonimbus
D. Altostratus
C. Cumulonimbus
