There is extraneous information in the diagram. There is duplicate information where you have... There are rivers flowing beneath our feet... a myth? Can stay because it’s simplified. The information ...Have you ever heard that there are rivers of water flowing underground? Do you think it’s true? should be deleted because it’s duplicating the simplified statement prior. Also, Some rivers, such as the Alpaha River in northern Florida, USA,can disappear underground during low flow periods isn’t relevant to the rest of the diagram.
