- 7. Multiple Choice
Which of the following actions causes the deposition of sand at a delta?
river water slowing as it enters the ocean
salt water & fresh water mixing together
ocean waves transporting sand toward land
ocean water slowing as it reaches the coast
- 8. Multiple ChoiceHow do plants weather rocks?During photosynthesisWhen roots grow into cracks of rocks and expand the rock breaks.When the plant moves water from the roots to the leaves, the rock breaks.Plants don't weather rocks.
