Air Parcels
This is an amount of air that moves as a unit.
Air parcel
This is the ultimate source of energy that causes weather to occur on Earth.
The sun
The gaseous form of water is known as this.
Water vapor
This is the measure of how hot or cold something is.
Temperature
This is the process by which a solid becomes a liquid.
Melting
An air parcel over the Pacific Ocean would have this characteristic.
High humidity
If an air parcel is warmer than the surrounding air, then this will happen.
Energy will transfer from it to the surrounding air
Water vapor in the air is specifically known as this.
Humidity
After an air parcel is warmed, it will do this in the troposphere.
Rise higher
This is the process by which a liquid becomes a solid.
Freezing
An air parcel over Antarctica would have these two characteristics.
Low temperature and low humidity
Energy transfer always happens in this direction.
From higher to lower energy
An air parcel that has higher humidity could result in a storm with greater amounts of this.
Precipitation
The temperature of an air parcel will decrease until is is the same as this.
The temperature of the surrounding air
This is the process by which a liquid becomes a gas.
Evaporation
Air parcels can rise higher and lower in this layer of Earth's atmosphere, where weather occurs.
Troposphere
In the thermometers we've used in class to measure air temperature, energy transfers from air molecules to this liquid inside.
Alcohol
Clouds form when this happens to the water molecules in the air.
They lose energy (energy transfers out)
If you have two air parcels with different starting temperatures, this is the one most likely to result in more rainfall.
The warmer one
This is the process by which a gas becomes a liquid.
Condensation
Air parcels are full of air molecules. The most abundant being this gas.
Nitrogen
The energy that causes the warming of the atmosphere comes directly from this.
Earth's surface
Dew point is the temperature at which liquid water droplets begin to do this.
Form
Higher temperatures have this effect on humidity.
Higher humidity
Phase changes occur because this changes.
The kinetic energy of the molecules (temperature)
