the mouth of a river is the ? of a river
usually where a river joins the ?
Back
Card 7
Front
velocity upstream:
faster/slower
because water is shallow
more/less friction between bed and banks
Back
Card 8
Front
velocity downstream:
faster/slower
water is shallow/deep from tributaries
more/less friction between bed and banks
Back
Card 9
Front
cross profile and valley downstream:
as ? bring more water from drainage basin, the river becomes bigger/smaller
with more water and ? it's able to erode its channel making it wider/narrower and deeper
