This is ace. Wolves were introduced back to Yellowstone National Park 70 years after they were last there. As a result the whole ecosystem was altered.
We often bang on in lessons about linking ideas together and how in real life there are so many knock on effects. Well have a look at this video and see for yourself
More wolves means less deer (especially in the valley floors where they are easier to hunt down).
Less deer means less grazing. Less grazing means vegetation can grow more.
More vegetation means less soil erosion. Less soil erosion means less material in the rivers.
But more vegetation on the valley floors also means more stable river banks. More stable river banks means straighter rivers in places.
The animals the vegetation the ecosystem and the rivers are all interlinked
You would do well to find a better page on the web to explain the differences between these two types of wave than the BBC Bitesize revision one. So click here to have a look. I have posted before about waves in general. You can read that here
There is also a video here, made by another teacher that explains it quite well. It comes with a music soundtrack from the 1980s – around about the time I took my GCSE (well it was called an O’Level in those days)
Typical exam questions on this might be:
Describe the 3 features of a constructive or destructive wave (3 marks)
Explain how a constructive or destructive wave shapes the coast. (4 marks)
Having just taught Blackpool as an example of a UK tourist resort, here is the link you need to access all the resources we used in class
Remember, you need to know …….
A case study of a coastal resort. 1) Why it grew 2) What problems tourists brought to Blackpool 3)How large tourist numbers are managed 4) How the resort plans to continue being successful in the future
Question 2 – Changing Urban Environments “Improving Squatter Settlements”
Question 4 – Development Gap “International Aid” (and how it is sustainable)
Question 6 – Tourism “Tourism in an Extreme Environment”
- Rocinha and the Favela Bairro
- Water aid (and fair trade if you wish)
I won’t link to all the resources on this blog for these 3 case studies. I am sure you can use the category cloud and find them. But here is a link to the skeleton revision cards I have produced that show the sections within each case study you need to know

Well done for getting through the Physical paper on Tuesday. Now there is about 12 days till your last Geography GCSE paper. Its the human paper.
The 3 topics we are doing are:
- Changing Urban Environments
- Development Gap and
They will be questions 2, 4 and 6 in the exam!!
HOW TO REVISE:
a) Go through a PLC (personal learning checklist) for each topic. to see what you know, partly know and don’t know.
changing Urban environments PLC
Dev Gap PLC
b) Revise the stuff you don’t know so well (don’t do the stuff you already know)
c) test your knowledge using past exam questions. These two links take you to all the foundation and all the higher papers over the last 5 years , as well as the mark schemes (so you can check your answers) and the inserts.
(I have already written an article about “Effective Revision” which happens to use tourism as an example so you could watch the video in that. Your PLCs have been updated since then though, so you would be better off using the 3 above)
Finally of course there are a few years worth of resources, revision help, videos et al on the blog so use those too. If you get really stuck ask a question to @stedsgeography on twitter
This video from the New York Times. It is useful to us for 5 reasons:
- It covers a lot of short term responses to the earthquake of 2015
- You can also see some of the effects of the quake.
- This short clip also illustrates how Nepal faces extra problems because it is a less wealthy country
- Finally, really good answers in the exam will talk about how the rural areas of Nepal with their inaccessibility meant both the effects were worse and the responses were made more difficult
- You can even use it in the Development Gap topic about how a natural disaster can hinder development in a country
And all in 3 minutes flat
Here is the powerpoint from the lesson. We covered: why rivers flood, meanders & ox bow lakes and the Rutland Reservoir case study
