Definitions
Definition of weather.
Conditions such as rain, clouds, and wind at a particular time and place.
Definition of air parcels.
Definition of temperature
A measure of how hot or cold something is.
Definition of wind.
The movement of air in a particular direction.
What can wind do?
Transport air parcels by pushing them higher up into the troposphere.
Definition of atmosphere.
The mixture of gases surrounding a planet.
The sun ______ the air parcels up, then it rises into the troposphere.
Heats
The higher the temperature, the higher the _______ rises.
Air parcels.
Air moving from areas of high pressure to area of low pressure is ______.
Wind
What is the first step of the water cycle?
The sun heat up the surface water (air parcels).
Definition of evaporation.
The process by which a liquid changes into a gas.
The warmer the air parcels are, the higher it ______.
Rises
Air parcels can be pushed up into the ______ by wind.
Troposphere
What is humidity?
The amount of water vapor in the air.
Definition of precipitation.
Rain, snow, sleet, or hail that falls from clouds onto the ground.
The higher the air parcels rises, the more _______ there is. Leading to more rain and clouds.
Condensation
How does temperature affect the amount of rainfall?
Warmer air can hold more moisture, leading to more rainfall when that air cools and condenses.
They cool down. It stops when its temperature is equivalent to the temperature of the surrounding air.
Definition of condensation.
The process by which a gas changes into a liquid.
Warmer air parcels hold more _______ than cooler air parcels.
Moisture.
What does wind do the air parcels?
It pushes the warm/moist air higher up into the air, causing it to cool and condense more effectively, leading to more rain.
What cause air parcels to expand when it cools?
Lower air pressure
