When drawing a Venn diagram to compare and contrast hurricanes and tornadoes, all their properties should be listed. Their similarities should be listed where the circles overlap, and their differences should be listed where the circles do not overlap.
Venn diagrams are usually drawn as circles that represent the similarities and differences between variables. The extent to which the circles overlap represents how similar or different the objects are. If two circles do not overlap at all, there are no similarities between the variables. If there is a small overlap, then there are only a few similarities; a bigger overlap suggests more similarities.
Tornadoes and hurricanes are similar in that both of them are types of storms with strong winds that cause significant damage. When drawing the Venn diagram, this similarity should be written in the zone where the two circles representing hurricanes and tornadoes overlap.
Tornadoes and hurricanes differ in the ways in which they are formed, the geographic regions where they occur, their shape and wind speeds. These differences should be listed in the respective circles for each storm type. For example, the circle for tornadoes should mention that tornadoes are formed over land, and the circle for hurricanes should contrast this by stating that hurricanes are formed over water.
