D. all the above are true
2. Low Pressure: Which is a false statement?

PRESSURE.
3. Warm Front: Draw the symbol (on the line) for a warm front.
(The semi-circles on line point in the direction the warm front is moving.)
4. Cold Front: Draw the symbol (on the line) for a cold front.
(The points that look like ice cycles show which direction the cold front in moving.)
5. Which is true about a cold front?
A. there is the boundary between warm and cool air. The warm air is
replacing (overtakes) the cold air. The warm air slides over the top of the
cold air. The water air rises, cools slowly, condenses into liquid clouds and
can produce light rain, snow, sleet or freezing rain.
B. there is the boundary between warm and cool air. The colder air is
replacing (overtakes) the warmer, moist air. The cold air pushes under the
warmer air. The warm air cools, water condenses and a thunderstorm can
occur.
6. What happens if there is a great temperature difference between air
masses?
A. nothing
B. only a cold front
C. only a warm front
D. severe weather such as a tornado can occur
7. Which is true about a warm front?
A. there is the boundary between warm and cool air. The warm air is
replacing (overtakes) the cold air. The warm air slides over the top of the
cold air. The water air rises, cools slowly, condenses into liquid clouds and
can produce light rain, snow, sleet or freezing rain.
B. there is the boundary between warm and cool air. The colder air is
replacing (overtakes) the warmer, moist air. The cold air pushes under the
warmer air. The warm air cools, water condenses and a thunderstorm can
occur.
