A huge, jagged rock sits atop a windy cliffside. Over a period of many years, how will the rock MOST LIKELY change?
Kaylis [27]

Answer: A huge, jagged rock sits atop a windy cliffside. Over a period of many years, how will the rock MOST LIKELY change? It will become larger and smoother.

                                 or

Option (D)

Explanation:

Wind erosion will take place extensively as the cliff-side is exposed on the outcrop. Due to the wind erosion, the large, jagged rock will undergo the process of weathering where the softer parts of the rock will be eroded much rapidly in comparison to the harder parts, as a result of which the overall size of the rock will decrease and the surface will be uneven and somewhat rough. This will take place over a due course of time. The main agent that is responsible for erosion is the wind.

Thus, the given rock will become smaller and less smooth after a definite period of time.

Thus, the correct answer is option (D).

Hope this helps..... Stay safe and have a Merry Christmas!!!!!!!! :D

a rural kansas watershed that is ungauged has an area of 475 acres and a main channel length of 6870 feet with an average slope
dlinn [17]

Answer:

\mathbf{Q_p  =682 \ \  ft^3/s}

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 t_c = 0.0078L^{0.77} S^{-0.385}

where;

L = 6870

S = 5/264

t_c = 0.0078(6870)^{0.77} (\dfrac{5}{264})^{-0.385}

t_c =32.34 min

Since 60 min = 1 hour

32.34 min will be (32.34*1)/60

= 0.539 hour

Lag time T_l = 0.67\times t_c

T_l = 0.67\times 32.34

T_l = 21.6678\ min

The time to peak i.e

T_p = \dfrac{D}{2}+ T_L \\ \\  T_p = \dfrac{15}{2}+ 21.6678 \\ \\  T_p = 29.168 \ min

T_r = \dfrac{T_p}{5.5} \\ \\  T_r = \dfrac{29.1678}{5.5} \\ \\ T_r = 5.30 \ min

Since D = 15 min is not equal to T_r, then we hydrograph apart from T_r duration lag time.

Then;

T_p \ ' = T_p + \dfrac{D-t_r}{4} \\ \\ T_p \ ' = 29.168 + \dfrac{15-5.30}{4} \\ \\ T_p \ ' = 31.593

Now, we need to determine the peak discharge Q_p by using the formula:

Q_p  = \dfrac{484 \times A}{T_p \ '}

where

484 = peak factor

Recall that A = 475 acres, to miles, we have:

A = 0.7422 mile²

T_p \ ' = 31.593/60

∴

Q_p  = \dfrac{484 \times 0.7422}{\dfrac{31.593}{60}}

\mathbf{Q_p  =682 \ \  ft^3/s}

How did people find there way before the invention of maps?
Zanzabum

They used the Moon and the stars at night as guides. In the daytime, they used rivers, mountain ranges, and cities as ways to find their way from one place to another.
