(measuring )
Measures the amount of rainfall.
(What is a rain gauge?)
An air mass that forms over water and is humid.
(What is a maritime air mass?)
Wind is caused by ____________ ________.
(What is convection currents?)
As elevation increases, temperature usually does this.
(What is decrease?)
A long-term increase in Earth’s average temperature.
(What is global warming?)
This device measures temperature.
(What is a thermometer?)
An air mass that forms over land and is dry.
(What is a continental air mass?)
Hot air _____ and cold air _____
Rises and sinks
The average weather conditions over a long period of time.
(What is climate?)
These types of gases trap heat in the atmosphere
Greenhouse gasses
This devise measures wind direction
(What is a wind vane?)
A warm, moist air mass originating from the Gulf of Mexico.
(What is a maritime tropical air mass?)
Particles like dust and ash in the atmosphere have this effect on temperature.
They cool the air by blocking out the sunlight
This is a climate zone located near the equator, has high temperatures and a lot of precipitation.
Tropical zone
This greenhouse gas is primarily released from burning fossil fuels.
(What is carbon dioxide?)
Used to measure wind speed.
Anemometer
This type of air mass brings cold, dry weather from Canada.
(What is a continental polar air mass?)
These winds occur at the poles and move east toward the equator.
(What are polar easterlies?)
What two main factors determine climate
Temperature and precipitation
The primary human activity that releases carbon dioxide into the atmosphere.
(What is burning fossil fuels?)
This device measures Air pressure.
Barometer
A boundary between two different air masses.
(What is a front?)
Convection currents are...
When hot material rises and and sinks due to density differences
Why is the equator warm and the pole cold
The sun is more concentrated at the equator and less concentrated at the poles
The process of cutting down forests, reducing the number of trees that absorb carbon dioxide.
(What is deforestation?)
