Part A – Fill in the Blanks
Fill in the blanks with the correct answer. Write the answer in the blank space at the front
of the question.
1. Five
satellites orbit the earth at about 36,000 km.
2. These five satellites take two kinds of pictures. One kind is an ordinary picture
such as we would take with a camera. The other is
that records
temperature radiation.
3. At about 700-900 km the

satellites collect data which
4. If we can get a big enough picture of what is going on in the troposphere now,
we can predict the weather. We can do this because we know that weather systems
travel at about _____ kph in summer and ______ kph in winter.
5. Global weather watching requires
cooperation.

Part B – True or False
True or False ?
1. In a high pressure area you can expect wet stormy weather.
2. Winds always blow towards higher pressure.
3. The greater the difference in pressure, the harder the winds will blow.
4. In a high pressure area, the air is sinking.
5. A low pressure area is often formed along the boundary, or front, between cold
and
warm air masses.
6. Because of the coriolis effect, winds converging on a low pressure area tend to
turn
clockwise in the Northern Hemisphere.
