Grade 8 Science and Technology Strand 5: Water Systems Write down two things that you know about rivers: Science Grade 8
I think you should probably look at your book for this, because clearly you are expected to come up with information from the book. We do not know what sorts of information you are supposed to put down.
After all, just based on this question, you could say that the answer is that 1) rivers are made up of water and 2) that the water in rivers runs downhill. Surely that's not what you're being asked.
A couple more important things about rivers, perhaps:
- All the water in a given area around the river drains into it. This means that runoff from agricultural fields can bring large amounts of chemicals into rivers.
- Rivers used to meander around, flooding their banks a bit here and there quite often. Now, they are forced into channels. When they overflow now, the results are much more catastrophic than before.
