Explanation:
Iguazu Falls are one of the highest waterfalls in the world and the biggest waterfall system in the world. The amount of water that falls down these waterfalls is enormous, and that combined with the height gives the water a lot of power. The water is carrying huge amounts of pebbles, rocks, the debris of all sorts and sizes, and they combined with the water manage to erode the bedrock.
As the water carries all of the material with it, it scratches the surface of the bedrock, and as it does it gradually makes the surface of the bedrock smooth. At the waterfalls themselves, the power with which the water and the material it carries are much bigger so they manage to create a very deep caldron-like hole in the bedrock below the waterfall, and plus smoothens its surface.
Economic development is able to continue in the absence of the resources that first drove it because:
- Countries can trade to get the resources
- Economic development allows for diversification
When a nation is unable to access the resources that made it quite successful, it can resort to buying that resource and then improving on it.
For instance, the U.K. used to produce sufficient coal but now import more than they produce.
Another way a nation can continue developing is diversification. The income gained from the resource that has now finished, will enable a nation to go into other economic activities which will continue their development.
For example, China used to export only agricultural goods but diversified into industrial.
In conclusion, a country can keep developing if their primary resource is finished thanks to trade and diversification.
