1) SORT THE FOLLOWING STATEMENTS ABOUT COLD AND WARM FRONTS INTO THE THINKING ORGANISER BELOW:
a) Cold and warm air meet
b) Cold air pushes into warm air
c) Warm air pushes into cold air
d) Cold air is below warm air
g) Thunder and lightning
h) Cirrus cloud
i) Stratus cloud
j) Cumulonimbus cloud
k) Usually move from west to east
2) ADD THE CORRECT WORD TO THE PARAGRAPH USING ONLY WARM OR COLD:
___________ and __________ fronts are where two different air masses meet. At a __________ front, cold air is pushing in to warm air. At a __________ front, warm air is pushing in to cold air.
__________ air always rises over __________ air. Cloud forms on both __________ and __________ fronts. The weather is usually more extreme on the __________ front, with heavier rain and possibly thunder, hail and lightning. Cirrus cloud is the first sign of a __________ front approaching. Where a __________ front is near the ground, you can expect to see featureless sheets of low, grey stratus cloud from which rain can fall. __________ fronts move faster than __________ fronts, leading to the formation of an occluded front. __________ fronts are marked with a semi-circle, pointing in the
direction the front is moving. __________ fronts are marked with a triangle, pointing in the direction the front is moving.
3) TRUE OR FALSE?
|Cold air pushes under warm air at a cold front|
|The weather is usually worse on the warm front|
|Warm air pushes into and over cold air at a warm front|

|The temperature is colder at a cold front than at a warm front|
|Cold fronts are marked by a line with triangles on it|
|Cold fronts usually travel from west to east|
|Warm fronts move faster than cold fronts|
Rewrite any of the statements that you think are false so they become a true statement.
