Define air pressure
How many gas particles there are pushing down on the air at any time
Land heats up faster _______________ but the ocean heats up faster ______________
during the day; at night
The four types of precipitation
Rain, snow, sleet, hail
What is denser: high pressure systems or low pressure systems?
High pressure systems
What needs to happen before there can be precipitation?
What is the relationship between air temperature and altitude?
The higher the altitude, the lower the temperature
The closer you are to the ground, the higher the temperature
The effect of the rotation of Earth on Global winds.
Uneven heating creates convection currents and rotation changes the movement of this air and makes it horizontal
The phase change that forms clouds.
What is condensation?
The front that brings thunderstorms.
What is a cold front?
The main heat source of the atmosphere.
What is the Sun?
I have two samples of gas with equal masses. Sample A is warmer than Sample B. Which sample has a higher pressure?
Sample B: sample A is warmer so the particles are going to be more spread out.
The driving force causing land and sea breezes to blow.
What is uneven heating?
What happens when the air is holding as much water vapor as it possibly can?
The water vapor will condense and form clouds/dew and there will be rain
Why does air pressure decrease as you go higher up in the atmosphere?
Most gas producing/using organisms live closer to the surface of Earth, and the force of gravity keeps particles lower in the atmosphere.
Which causes cloudy weather: high pressure system or low pressure system? Why?
Low pressure system because the air is less dense and rises, but in a high pressure system the air sinks so no clouds form.
Describe what is happening during a sea breeze
The land heats up faster than the ocean, so warm air above the land rises and cool air from the ocean moves in to fill the empty space
The relationship between humidity and temperature
The higher the temperature, the more water vapor the air can hold
Draw the lines used to represent the four different types of fronts on a weather map.
