Answer:
Explanation:
Given that:
Area = 475 acres
The length of the channel (L) = 6870 feet
The average water shield slope (S) = 100 feet/mile
Since; 1 mile = 5280 feet
Burst duration D = 15 min
∴
100 feet/mile = 100/5280
The average water shield slope (S) = 5/264
Using hydrograph method:
The time of concentration 
where;
L = 6870
S = 5/264
min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time 
The time to peak i.e
Since D = 15 min is not equal to 
, then we hydrograph apart from duration lag time.
Then;
Now, we need to determine the peak discharge 
by using the formula:
where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²
∴
D) all of the above
it is mostly A tho, but im pretty sure there are tourists that go there and that melting water is used for hydro-power too.
So D is your best choice
hope this helps
The correct option is C.
Plate tectonic theory explains the structure of the earth's crust and the many phenomena that are associated with it. This theory enables the scientists to know that there are movements in the interior of the earth which are responsible for volcanic eruptions and earthquakes.

Explanation:
Humans use the Earth's natural resources for a number of purposes, including: energy and fuels for warmth. building materials for shelter. fuels for transport. Earth is the home planet, right for life. But rights, a notable political category, is, unfortunately, a biologically awkward word. Humans, nonetheless, have rights to a natural environment with integrity. Humans have responsibilities to respect values in fauna and flora. Appropriate survival units include species populations and ecosystems. Increasingly the ultimate survival unit isgloba l; and humans have a responsibility to the planet Earth. Human political systems are not well suited to protect life atglobal ranges. National boundaries ignore important ecologicalprocesses ; national policies do not favor an equitable distribution of sustainable resources. But there are signs of hope.
Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals.
