Astream is flows towards the southeast. it is 50 miles long and it flows from a mountain spring 3450 feet above sea level. the stream discharges into a river at an elevation of 1100 feet above sea level. what is: a) the bearing of the stream's headwaters and b) what is the gradient of the stream? a) southeast, b) 47 feet/mile a) northwest. b) 47 feet/mile a) northwest. b) 4 feet/mile a) northeast, b) 400 fcet/mile a) southwest, b) 40 feet/mile

a) northwest. b) 47 feet/mile

Explanation:

The gradient of a stream is calculated by subtracting the dis charge height from the height of its headwater and then divided by the distance the stream covers or its length.

Here the height of the headwater = 3450 feet

                            dis charge height = 1100 feet

                                          distance = 50 miles

The gradient of the stream = (3450 feet - 1100 feet) / 50 miles

                                             = 47 feet/mile

A Stream's  gradients is usually higher in a stream’s headwaters than at dis -charge

If he bearing of a stream is SouthEast then that of its headwaters is NorthWest.

if he does not use open the compass the a width greater than half of po, he will not be able to find the midpoint of the line, without the midpoint of the line, he will not be able to bisect the line.   to find the midpoint of a line the circles drawn with a compass must either intersect or be touching.

i think option c is most appropriate
