Today we are going to be investiigating how the Norfolk coast has changed. If you follow my digimap instructions below, you should arrive at this map. The thin blue line is where the sea reaches when it comes in ( it's not a river)

Today's Geography task
To see how the coast line at Happsiburgh in Norfolk has changed since the 1890s.
1. Once you've logged in,
Click the little arrow next to the filing cabinet.
2. You should see the Class 4 Coasts 29th April folder
so now click on this.
3. You should now see 'The moving coast',
so now click on this. You are now on our work map.
4. Now choose the line tool from the drawing option - and scroll down and choose a colour.
5. You can now draw along the length of the coast (the blue line) from the top cross, right down to the bottom cross This shows you where the sea hits the land at high tide.
6. Now click on the 'Map Selector' at the top left, and in the left column, choose 1950s - then slide the slide to the left. Lets see where the sea came in 70 years ago.
7. Now do the same thing as above - choose a different colour and draw along the line of the coast (its black not blue here, and passes behind the Happisburgh' for a short distance).
8. Now go back to instruction number 6, but choose 1890s, choose a new colour and do the same again.
9. Now you should have three coloured lines showing where the sea has moved further away from the coast.
10. Now, slide the map Selector slider back to the right, and click on 'Aerial'. This will show you an aerial photograph of the coast now.
If you have a printer, try to print a copy out for your book - you can use the browser print option, or maybe use a snip tool, or just photograph it.
Your Investigation task:
is to measure how far the sea has worn away the coast since 1890.
- Look along your first line and find the point where you think the land in the 1890s was the furthest distance out to sea..
- Measure the distance with the measuring tool you used last week.
Question: What has happened here at Happisburgh and why has it happened?
What do you think?
Challenge: How far from the sea has the lighthouse moved since the 1890s.
These 2 short Espresso films help explain what's happening.
Let me know how you got on!
