Boston is just above sea level.
True or False |
True
|
|
|
What is the device called that measures air pressure?
|
Barometer
|
|
|
What are the two main types of barometers?
|
Mercury and Aneroid
|
|
|
What is air pressure measured in inches of?
|
Mercury
|
|
|
What happens when air in the atmosphere is warmed?
|
Particles of air move farther apart and air pressure gets lower
|
|
|
What happens when air is cooled?
|
Particles move closer and the air pressure gets higher
|
|
|
Wind is
|
moving air particles
|
|
|
When the difference in pressure between two areas are great are winds strong or weak?
|
Strong
|
|
|
The direction of the wind is the direction from which it is blowing. What is the direction of wind blowing from east to west
|
East wind
|
|
|
A device used to find wind direction is a
|
wind vane
|
|
|
A cloth bag that is narrow at one end and open at both ends is called what?
|
Wind Sock
|
|
|
How can you try to figure out wind speed if you don't have a special device to measure it with?
|
Beaufort scale
This is a scale to estimate wind speed based on mostly observation. |
|
|
How many forces does the beaufort scale have ?
|
12
|
|
|
The amount of water vapor in the air is called________.
|
Humidity
|
|
|
The amount of water vapor the air holding at a given temperature compared to the total it could hold at that temperature is _____________
|
Relative humidity
|
|
|
When water evaporates it changes from a liquid to a gas
True or False |
True
|
|
|
When water vapor condenses it changes from gas to a liquid
True or false |
True
|
|
|
When water evaporates it changes from a gas to a liquid
true or false |
false
|
|
|
When water vapor condenses it changes from a liquid to a gas
true or false |
false
|
|
|
What is billions of tiny drops of water condensed from the air?
|
A cloud
|
|
|
What is fog?
|
A cloud that touches the earth's surface.
|
|
|
Any form of water that falls to the earth's surface
|
Precipitation
|
|
|
What is used to measure the amount of precipitation
|
Rain Gauge
|
|
|
What are four forms of precipitation?
|
Rain, drizzle, snow and hail
|
|
|
What are the four main parts of the water cycle?
|
Evaporation
condensation precipitation accumulation |
|
|
Evaporation,condensation,
precipitation and accumulation are called the ______________. |
The water cycle
|
|
|
Why would you have more trouble breathing if you were mountain climbing?
|
Air pressure becomes less as you climb a mountain. Less air pressure means less oxygen
|
|
|
How is the Beaufort scale different than an anemometer?
|
The Beaufort scale estimates wind speed by mostly observation and the anemometer is an device that measures wind speed.
|
|
|
The water cycle is the continuous movement of water from the ocean to air and land then back to the ocean in a cyclic pattern.
|
This water vapor then rises to the earth's atmosphere where it cools and condenses (gas to liquid) into liquid droplets.
|
|
|
These droplets combine and grow until they become too heavy and fall to the earth as precipitation.
|
Water accumulate and runs off land collecting in rivers, lakes and oceans and the cycle starts all over again.
|
|
|
The sun heat's the earth's surface water causing the water to evaporate. (liquid to gas)
