Rainforest data
Rainforests grow in tropical countries with hot and humid climates. Look carefully at the line and bar graphs below which
have been assembled for Singapore’s annual temperature range and annual rainfall pattern.

(b) Annual rainfall pattern, Singapore
Now use the climate data below to create a temperature line graph and rainfall bar graph for each of the three locations.

Now grab an atlas and check where Singapore and the other places lie in relation to the Equator. Compare the four sets
of graphs. What conclusions can you draw about these locations and the climate as you move away from the Equator?

Remember!
• Use a line graph to represent temperature.
• Use a bar graph to represent rainfall.
• The average annual temperature or rainfall is calculated by adding all the respective figures for one year and dividing
this total by 12 (because there are 12 months in a year).
• Temperature range is found by using the following formula:
highest temperature – lowest temperature = temperature range
