7 The maps below show the odor
fields from a neighborhood hamburger barbecue. An
X marks the exact location of the barbecue grill. The wind was blowing from the northeast
when map A was drawn. Map B represents the same area drawn 1 hour
after map A
Which conclusion about what happened during the hour is best supported
by comparing these two maps?
The field values changed at many places.
2 The wind direction remained constant.
3 The odor became stronger in the western section of the
4 The size of the field grew.
8 Which equation can be used to
correctly calculate the air-pressure
gradient between two locations?
9 If the axis of Earth were not tilted relative to the plane of
around the Sun, the result would be
a greater number of hours in a day
2 a greater number of days in a year
3 a reversal of polar and equatorial climates
4 an equal number of hours of daylight at most locations
10 If the distance between the
Moon and Earth were double its present
distance, the Moon's cycle of phases would occur
in reverse order and more slowly
2 in reverse order and more quickly
3 in the same order but more slowly
4 in the same order but more quickly
11 The apparent daily movement of
the Sun across the sky is caused
Earth's rotation on its axis
2 Earth's revolution around the Sun
3 the Sun's revolution around Earth
4 the Sun's rotation during a 24-hour period
12 Changing the color of the roof
of a house from light to dark would
probably increase the amount of solar energy that is
