15 Questions
Which instrument is used to measure air pressure?
Barometer
What is the relationship between air pressure and altitude?
As altitude increases, air pressure decreases
What is the measure of water vapor within the air called?
Humidity
Which type of air mass has lower pressure at its core and higher pressure around the edges?
Low-pressure air mass
What causes clouds to form?
Condensation
Which weather factor is influenced by humidity?
Cloudiness
What is the movement of air caused by the uneven heating of the Earth's surface called?
Wind
What determines the speed and direction of the wind?
Temperature difference between air masses
Which one of the following best describes the difference between weather and climate?
Weather is the current state of the atmosphere at a specific location and time, while climate is the average pattern of weather over an extended period.
Which of the following factors affect weather?
Temperature, air pressure, humidity, cloudiness, and wind.
What is temperature?
Temperature is a measure of the kinetic energy within the particles of an object.
How does an increase in air temperature affect the chances of rain and thunderstorms?
An increase in air temperature leads to an increase in the chances of rain and thunderstorms.
How does temperature vary with height above sea level?
Temperature decreases with an increase in height above sea level.
What is climate?
Climate is the condition of the atmosphere in a specific area over an extended period.
How often is climate determined?
Climate is determined over an extended period, usually 30 years.
Study Notes
Atmospheric Concepts
- Air pressure is measured using a barometer.
Altitude and Air Pressure
- There is an inverse relationship between air pressure and altitude, meaning air pressure decreases as altitude increases.
Atmospheric Humidity
- The measure of water vapor within the air is called humidity.
Air Masses
- A low-pressure air mass has lower pressure at its core and higher pressure around the edges.
Cloud Formation
- Clouds form when air cools to its dew point, causing water vapor to condense into droplets.
Weather Factors
- Humidity is a weather factor that influences the likelihood of precipitation.
Wind Patterns
- The movement of air caused by the uneven heating of the Earth's surface is called wind.
- The speed and direction of wind are determined by pressure gradients and the Coriolis effect.
Weather vs. Climate
- The main difference between weather and climate is that weather refers to short-term conditions, while climate refers to long-term patterns.
Climate Factors
- Temperature, humidity, and atmospheric pressure are all factors that affect weather.
Temperature Concepts
- Temperature is a measure of the average kinetic energy of air molecules.
- An increase in air temperature increases the chances of rain and thunderstorms.
- Temperature typically decreases with an increase in height above sea level.
Climate
- Climate refers to long-term patterns of atmospheric conditions in a particular region.
- Climate is typically determined over a long period of time, often 30 years or more.
