What is the dew point?
The dew point is the temperature at which air becomes saturated with moisture and water vapor begins to condense into liquid.
True or False: The dew point is always lower than the air temperature.
False
Fill in the blank: Humidity is the measure of the amount of ______ in the air.
water vapor
What are the two main types of humidity measurements?
Absolute humidity and relative humidity.
What is relative humidity?
Relative humidity is the ratio of the current amount of water vapor in the air to the maximum amount of water vapor the air can hold at that temperature.
What happens when relative humidity reaches 100%?
The air is saturated, and condensation occurs, leading to cloud formation or precipitation.
Multiple Choice: Which process is NOT part of the water cycle? A) Evaporation B) Condensation C) Compression D) Precipitation
C) Compression
What is evaporation?
Evaporation is the process by which liquid water is transformed into water vapor.
Short Answer: What role do clouds play in the water cycle?
Clouds store water vapor and release it as precipitation, returning water to the Earth’s surface.
What is condensation?
Condensation is the process where water vapor cools and changes back into liquid water, forming droplets.
True or False: Clouds are made up of solid particles.
False
Fill in the blank: The process of water vapor cooling to form clouds is called ______.
condensation
What are cumulus clouds?
Cumulus clouds are fluffy, white clouds often associated with fair weather.
Multiple Choice: Which of the following clouds is typically associated with thunderstorms? A) Stratus B) Cirrus C) Cumulonimbus D) Altostratus
C) Cumulonimbus
What is the significance of the water cycle?
The water cycle is crucial for distributing water across the planet and supporting all forms of life.
What is the main source of energy driving the water cycle?
The Sun.
True or False: Higher temperatures generally increase the air’s capacity to hold moisture.
True
What term describes the amount of water vapor present in a given volume of air?
Absolute humidity.
Fill in the blank: The process of water movement from the surface to the atmosphere is known as ______.
evaporation
What type of cloud is typically layered and covers the sky?
Stratus clouds.
Short Answer: How does temperature affect relative humidity?
As temperature increases, relative humidity decreases if the amount of water vapor remains constant.
What is the role of condensation nuclei in cloud formation?
Condensation nuclei provide surfaces for water vapor to condense upon, forming cloud droplets.
Multiple Choice: Which phenomenon occurs when warm air rises and cools, leading to cloud formation? A) Inversion B) Convection C) Frontal lifting D) Both B and C
D) Both B and C
What is the difference between weather and climate?
Weather refers to short-term atmospheric conditions, while climate refers to long-term average weather patterns.
True or False: Clouds can form at any altitude in the atmosphere.
True
What is the primary factor that determines the type of cloud formed?
The temperature and humidity of the air.
