ABSTRACT
Statistics and graphics programmes will provide keys and legends, label axes and format students' data. Students must be critical and make sure the information presented is exactly what students need. Geography, environmental and earth sciences are visual subjects. Graphics, drawing, plans and mapping are core features. Teaching sessions are usually supported with visual materials because they are very effective ways to convey information. Everyone doing science or map work at school learns to add labels, scales, legends, keys and titles because every map and diagram must have them. Plotting, sketching or mapping is used to exemplify and clarify spatial relationships. Sketch maps highlight specific geographical and geological evidence. Either sketch freehand or use a published map as a base, and annotate copiously. A rough sketch can convey considerable geological, environmental and geographical evidence, making sketches invaluable in reports and essays.
