Describe the characteristics of the water at the mountain source:

speed:

temperature:

oxygen level:

nutrient level:

The characteristics of the water at the mountain source will be as follows:

- Speed; the speed will be bigger, and this due to the bigger fall through which the water passes down the mountain's steep slopes.

- Temperature; the temperature will be lower, and this is due to the lesser influence of the sun on the water, both, because of its speed, and because of the shade from the forest (assuming there's a forest on the mountain).

- Oxygen level; the oxygen level will be big, because the water in this part is the purest, and doesn't have debris in it, or it has it very small amounts.

- Nutrient level; the nutrient level will be relatively low, because the water is cold and quick, as well as steep, there isn't a big chance for large nutrition base to form in that part of the stream.

which three statements are true about all alloys?

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
