Find the right answers!

1) Why do weather balloons burst at altitudes between 30 and 35 kilometers?    The balloons burst, because:
a) very aggressive birds fly in this region.
b) the air pressure decreases with increasing altitude and the gas
    inside the balloon expands more and more.
c) the balloons are equiped with a self destruct mechanism. This
    mechanism explodes the balloon at these altitudes.
d) sunlight destroys the skin of the balloon at these altitudes.

2) Which measuring method uses the interaction of molecules and light?
a) SONAR
b) SODAR
c) LIDAR
d) RADAR

3) Which measuring device is used to make measurements at altitudes above 40 km?
a) satellites
b) airships
c) weather balloons
d) research air planes

4) What proportion of the stratosphere does the ozone layer take up?
     It is about:
a) 1/10.

d) 1/1000 000 000.

5) Which statement(s) is (are) true?
a) In the troposphere, the temperature increases with increasing
    altitude.
b) The tropopause is a very calm region of the atmosphere.
c) In the stratosphere, the temperature decreases with increasing
    altitude.
d) The tropopause is characterised by a temperature minimum.

6) What is the air pressure at a height of 11,000 metres?
