Layers of the Atmosphere
Temperature decreases in this layer as elevation increases and it is where most weather happens.
What is the troposphere?
Energy that is transferred by physical contact of one object to another.
What is conduction?
Fast moving air molecules that strike your skin will cause you to sense this as what type of temperature?
What is higher temperature?
Radio signal transmission is greater at night because of this phenomenon.
What is the ionosphere moving higher at night allowing radio signals to bounce further?
A temperature scale, such as kelvin, that has its zero point at absolute zero, the coldest temperature that is theoretically possible.
What is Absolute Temperature?
This layer is composed of light gasses such as helium and hydrogen. Air molecules and atoms are extremely far apart.
What is the exosphere?
Pressure differences in the air of the Earth's atmosphere are caused by this.
What is the uneven heating of Earth's surface?
The formula for determining atmospheric pressure.
What is force/area?
The reason the thermosphere does not feel warm even though it is as high as 2,000 degrees celcius.
What is because the air molecules and atoms are so far apart from each other.
A box of weather instruments carried by a weather balloon.
What is a radiosonde?
At this layer temperature increases as elevation increases due to gasses absorbing X-Ray and some UV radiation.
What is the thermosphere?
As elevation increases this happens to the atmospheric pressure.
What is the pressure decreases?
Wind blows from areas of ____ pressure to areas of ____ pressure.
What is high to low?
Despite our need for oxygen, this is the most abundant gas in teh atmosphere.
What is Nitrogen?
A measure of the average speed of molecules or atoms in a substance.
What is temperature?
Temperature increases as elevation increases at this level. Most aircraft travel in this level.
What is the stratosphere?
Energy that can be transferred by electromagnetic waves and don't need molecules.
What is radiation?
____ air can hold more water vapor than _____ air.
What is warm and cold?
The reason a DRY heat can feel more 'comfortable'
What is our body cools itself by the evaporation of sweat off of our skin, so in a dry environment this evaporation can happen more efficiently and rapidly.
The temperature at which air must be cooled to become saturated with water vapor, meaning that it can no longer hold additional water vapor.
What is dew point?
The temperature decreases at this level as the elevation increases and the coldest part of earth's atmosphere is here.
What is the mesosphere?
The zone within the thermosphere characterized by ionized gases which reflect some radio signals back towards the surface.
What is the ionosphere?
The ratio of the amount of water vapor in the air compared to the maximum amount of water vapor the air can hold at a given temperature.
What is relative humidity?
The reason the sky is blue.
What is sunlight is composed of all colors however as light enters the atmosphere it interacts with molecules in the air and certain wavelengths scatter more than others. These blues and violets that scatter are then picked up in our visual field from all directions, and so we perceive the sky as blue.
A weather instrument used to weather wind speed.
What is an anemometer?
