No, it decreases. The velocity is highest and the channel narrowest at the headwaters.Does a river's velocity generally increase as one travels towards the river's mouth?
A cone of depression occurs when you drop your scoop of ice cream on the ground on a hot summer day.
No, the velocity is definitely higher upstream, where there can be rapids and waterfalls. The fast-flowing water is able to pick up a lot of sediment. As you get downstream, it can no longer hang on to all the debris, so some of it is deposited. Downstream, there are lots of meanders and sediment deposits, which can form braided streams.Okay. Thanks (:
EDIT: I just took a little review test for the physical portion of this event (so basically stuff on rivers) and when I checked it, the answer key said that the velocity increases as one proceeds downstream in a river. The test came from a textbook, so it should be pretty reliable...
The only information that you really need: Range, introduction, how it is a threat to humans, how it is a threat to ecosystem(s), and of course, what it looks like! They look very different, though, especially the three animals.Hey, do you know where I can get some good info on nuisance species? I know this wiki provides some information, but it doesn't have as much as I would like...
Hey, I did not take the test, however I do think I can help you. Mayfly nymphs and damselfly nymphs look similar in the fact that they both of 3 tails. However, a mayfly's tail is not considered a "true tail" and looks more wispy than the tails of a dragonfly. Also, you can look at their leg alignment. The way you can tell dragonflies and damselflies apart is by the thickness of it's body and the way their wings rest. Hope that helps :]Did anyone take the PA States C division test?
What did you think of the bugs/ what were they? I think I ended up putting mayfly for two of the bugs and I wasn't sure if one was a dragonfly or a damselfly (it had the dragonfly eyes but it was really small....)
