As altitude increases, air pressure _________
What is McDonalds slogan?
I'm Lovin' It
The energy source of the water cycle
This process is the continuous movement of water throughout Earth's atmosphere
The layer where weather occurs
Troposphere
This is where the ozone layer is located
Stratosphere
What is air pressure?
weight of earths atmosphere pressing down on everything at the surface
Evaporation
Water that collects in rivers, streams, and oceans
Runoff
The hottest layer of Earth's atmosphere
Thermosphere
The ozone layer protects us from this.
UV radiation
This instrument measures air pressure
Barometer
The 4 types of precipitation
Rain, snow, sleet, hail
Gas cooling and changing into a liquid
Condensation
Earth's atmosphere is 78% of this gas
Oxygen makes up ____% of Earth's atmosphere
21%
Why is it harder to breathe at the top of a mountain?
There is lower air pressure, so fewer oxygen molecules per breath.
The process of water evaporating from plants
Transpiration
Water that is absorbed into the ground and forms into pockets of water
Groundwater
The MAIN factor causing the atmosphere to be divided into 5 separate layers
Differences in temperature
The process by which the atmosphere traps the Sun's radiation to warm the Earth
Greenhouse effect
What is air pressure like in the troposphere vs. exosphere?
In the troposphere, the air is heavy and thick, pressing down on us. In the exosphere, it’s so thin that it’s almost like there’s no air at all.
When warm water vapor hits cold air, this is formed
A cloud
The temperature is must be for precipitation to be snow
32 degrees or below (freezing)
