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

2. 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

3. 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

4. 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”

5. 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”

6. 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.
