GeoWilmington>Year 7>Earth’s Topography map (TABLET version) GeoWilmington>Year 7>Earth’s Topography map (TABLET version). Have your ‘####_wgsg’ ArcGIS login ready. Students open the map. The link http://arcg.is/2cMMAXy is on GeoWilmington. Use the handouts with the credentials to view the map

Homework instructions: Log into ArcGIS (link on Geowilmington) Use the next 3 slides to help you label your map You need to label using codes Do not colour: Ice sheets = IS Plains = PLN Mountain Range= MR Plateau= PLAT If you have time label the ocean features also Mid-ocean ridges: MOR Ocean trenches: OT Continental shelves: CS Abyssal plains: AP

Terrestrial topography (Ice sheets) Turn on layer 8 only Ice sheets are large and white. Altitude over 2000m. Use pencil and write “IS” on your map

Terrestrial topography – (Plains, Mountain ranges, Plateaus) Layers 2 and 3 only. Plains are green. Altitude under 200m. In pencil write: “PLN” Mountain ranges are brown in narrow belts. Altitude 2000m. In pencil write: “MR” Plateaus in yellow/brown. Mostly 1000m (from 400m to 5000m). In pencil write “PLAT”

Marine topography Layers 4, 5 and 6 Mid-ocean ridges are lightish blue. Depth approx. 3000m. In pencil write: “MOR” Ocean trenches are dark blue in very narrow belts. Depth 6000m. In pencil write: “OT” Continental shelves are very light blue. Depth less than 100m. In pencil write “CS” Abyssal plains are large dark blue areas. Depth 5000m. In pencil write “AP”

IS Orange Yellow Green Light Blue Dark Blue Purple Red Hand out the world maps. Students will need to colour code and annotate their map (see next slide). This is their visual literacy assessment.
