Rivers are more_than_water

  1. 1. Rivers are more than water Keith Le Matti
  2. 2. Young, Mature, and Old Age There are three different STAGES of rivers: the youthful stage; the Maturity of a river; and the river’s Old Age. The differences between these types of rivers are very obvious. They all have very different processes, and change / communicate with the landscape that surrounds them in different ways.
  3. 3. Young, Mature, and Old Age • Youth • Another name for the youth of a river is the river’s source • When a river is young, it is fast • It erodes the land faster than in its older stages • These rivers are located high up in the mountains, forests, etc, in landscapes that have a very high elevation The youthful stage of a river
  4. 4. Young, Mature, and Old Age Maturity • In the maturity of a river, erosion changes • The river begins to erode sideways (horizontally) • This creates meaners (bends in the river) as it moves closer to ground level (0 metres of elevation)
  5. 5. Young, Mature, and Old Age Old Age • The final stage in the river has many meanders • It is the slowest stage of the river, and flows at almost ground level • Here, deposition occurs • The river lets go of its rocks and other materials (the load), which is left at the bottom of the river • These processes of the old river make lakes that are separate from the river
  6. 6. Other types of rivers We can identify different landscapes created by rivers: • Estuary • Delta • Lake • Rejuvenated river • Bays
  7. 7. Back to business… Rivers are a lot more interesting than just being water running through the world Rivers provide so much life everywhere, without rivers, forests and parts of the countryside wouldn’t survive to the extent that it does Rivers give life to villages, towns, and cities through the nutrients (like little pieces of life) they give to the green landscape
  8. 8. People and Rivers We interact or communicate with rivers • We use rivers for transport, build bridges to move across the landscape • We use rivers for sport and athletics • Rivers are used for tourism • People visit countries to see these beautiful landscapes, and this gives money to the governments of those countries
  9. 9. The River Nile - Egypt
  10. 10. The River Nile - Egypt • It’s 4,150miles long, and it’s the second longest course of water in the world • However, most of the tourism in Egypt is centred on this phenomenon
  11. 11. Estuaries • Estuaries are bridge environments between rivers and oceans • They are influenced by river processes • This includes deposition at the mature and old age stages of a river, and erosion of the youthful and mature stages • They also see oceanic processes, for example tidal waves, erosion of coastal areas, etc
  12. 12. Estuaries • What was an estuary? • Estuaries can come from river valleys near or far from coasts that have been drowned by flooding and / or high tides from the sea • They can also be created by the movement of plates, of oceanic into continental crust
  13. 13. Bays and estuaries • https://www.youtube.com/watch?v=ryrXAGY1 dmE
  14. 14. Bays and estuaries • The Giants Causeway was formed when the North American plate and the Euroasian plate moved apart millions of years ago • From the core of the earth, magma spilled across the ocean as lava, and deposited these landscapes of basalt rock
  15. 15. Bays and estuaries
  16. 16. Estuaries
  17. 17. Bays and Estuaries
  18. 18. Bays • A bay is a part of the sea/ocean, or a lake which is between two pieces of land on the coast • Bays can be created by the processes of glaciation (ice), volcanism (volcanoes), and changes in the sea • Bays can also be estuaries
  19. 19. Bays • The water in bays is calm, tranquil • Because of the land on either side of the water, winds are not strong • The bay of Bengal is the world´s largest bay • The land on either side is from two different countries • The continents moved apart, and the bay was created
  20. 20. The Bay of Bengal
  21. 21. Dundalk Bay
  22. 22. Lakes • A lake is a standing body of water • What does this mean? • It means that it has no connection with the ocean • They can be connected to rivers, that can make the lakes bigger, or make them smaller
  23. 23. Lakes
  24. 24. Rivers on Mars Life on other planets
  25. 25. This is Dao Vallis, an interesting river system on the surface of Mars. It is a river that flows below a large volcano named “Hadriaca Patera.” I think that the river has communicated with the volcano. This interaction has made a number of landforms between the two landscapes. We will compare it with pictures of some rivers on planet Earth.
  26. 26. Dao Vallis and Earth Similarities •Dao Vallis is constructed by big flood called a “megaflood”, which was strong enough to flood all of Spain. •Valleys in the river channel are similar to channels of rivers on Planet Earth
  27. 27. Conclusions • Look at the earth image on the bottom right, then look at the image of Mars on the left, do they look similar? What do you think?
