EROSION - This process is a chemical process where acids carried in the river water dissolve the minerals in the rock and soil of the river bank and beds. Some rocks such as limestone are more easily eroded in this way.
EROSION - This process is where the river current swirls and flows against the river banks and beds and wears them away. It is particualry effective against lose soft materials and is most active in turbulent waters.
EROSION - This process is where the rock particles carried by the river scrape against the rocks of the river bank and beds so that they are gradually worn away. (Another word for this process is CORRASION).
TRANSPORTATION - This process is where the bed load (the large boulders) are rolled along the bed of the river by the force of the river current. The larger the boulders, the more energy the river needs to move them.
TRANSPORTATION - This process is where material moves along the river bed in a series of short hops. Turbulent currents lift a particle for a short distance. The particle then falls back to the river bed and is lifted again or dislodges another particle and the process is repeated.
TRANSPORTATION - This process is where the very fine load is dissolved in the river water and is then carried along in solution. It cannot therefore be seen and only actually represents a small percentage of the total river load.
EROSION - This process is the wearing down of carried rock particles as they knock against each other and the river banks and bed. They gradually become smaller and more rounded. It only applies to the carried load.
TRANSPORTATION - This process is where small, light particles are carried along within all the levels of the river. This gives the river a muddy look at times of flood when the river has more energy.
