THE WEATHER
What is the engine of the weather "machine"?
The sun
To messure the atmospheric pressure we use...
a barometer.
There are five layers in the atmosphere which are...
Troposphere, Stratosphere, Mesosphere, Thermosphere or Ionosphere and Exosphere.
The air is made up of the following gases...
Nitrogen, Oxigen, water vapour and Carbon Dioxide.
Thermosphere is between... (refering to altitude)
80 and 500 km up from Earth's surface.
Weather maps help us to ...
predict bad weather.
Atmospheric pressure is ...
the force or the weight of the air.
It's the layer in which Northern Lights are produced and where International Space Station orbits.
Thermosphere
Nitrogen is pressente in air in a (say the percentage)
78%
Mesosphere takes part from........ to ........ km.
50 to 80 km
What are the six variables to describe weather?
Sunshine, temperature, atmospheric pressure, wind, humidity and precipitation.
The unit of pressure in the International System is...
the Pascal (PA).
When stardust enters the atmosphere and meets the gases, it's appears to shine producing... (say the phenomenon and the layer in which it takes place).
Shooting stars in the Mesosphere.
What are the sources of air pollution?
Chemical pollutants.
Physical sources.
Biological contaminants.
Stratosphere goes up to a height of...
50 km.
In an anticyclone (above 1013mb) the air compresses and...
decends and warms up, which results in clear weather.
In the past, the air pressure was measured with a millimetre fo mecury because of...
Torricceli's experiment.
Where all the meteorological phenomena occurs, where the majority of gases are and and where all living processes take place is....
The Troposphere layer.
Examples of chemical pollutans are...
CLUE (they are NOT the volcanic eruptions, fires, engine combustions...)
nitrogen oxides (NO2, NO3), carbon monoxides (CO), and carbon dioxide (CO2)
The percentage of gases in Mesosphere is...
0.1 % of atmospheric gases.
Below 1013 mb, in low pressure areas or storms, the air...
expands and cools, which causes water vapour to condense and form clouds.
In Torriccelli's experiment, the glass tube with mercury measured...
760 mm.
Responsible for the protective function of the atmosphere. (Say the layer of the atmosphere and the gas that protect us)
Troposphere with the ozonosphere that protect us from ultraviolet radiation from the Sun.
sound level meter in decibels.
The Troposphere expands from the Earth's surface to...
8 or 14 km whether we are at the poles or at the Equator
