Describing Process Diagrams

Process diagrams are different from all other Task 1 visuals. Instead of describing data, you describe how something works or how something is made. This requires a different vocabulary set and a different approach. Process diagrams test your ability to write clearly about sequences of steps.

What Process Diagrams Show

Process diagrams illustrate:

• Manufacturing processes (how cement is made, how chocolate is produced)
• Natural processes (the water cycle, how a volcano erupts)
• Systems (how a power plant generates electricity)
• Life cycles (the stages of a butterfly's development)

They typically include:

• Arrows showing the direction and sequence of steps
• Labels identifying stages, materials, or equipment
• Numbers or letters indicating the order of steps

Key Differences from Data Visuals

Data Visuals (graphs, charts, tables)    Process Diagrams
═══════════════════════════════════════════════════════════
Describe trends and comparisons           Describe steps and stages
Use past tense for past data              Use present simple (processes are general)
Include specific numbers                  Rarely include numbers
Use comparative vocabulary                Use sequencing vocabulary
Active voice common                       Passive voice essential
