Rivers
1) change the landscape through erosion
2) are large bodies of contained water
3) usually begin low-lying valleys
4) are usually found near the poles
Which is the correct anwsee
I would prefer 2, most likely it is the answer because even though a river moves it is a large body of contained water, Or you could go with 1 because rivers are formed by landscape change through erosion. I would pick 1
