8. In most of the continental US, what fraction of annual precipitation actually moves directly into streams and rivers as surface runoff (without infiltrating into the ground or returning to the atmosphere via evapotranspiration)?
In most of the continental US, only a third of runoff transfers the continental surplus to balance the deficit of the ocean's fraction of annual precipitation.
Water Cycle and Surface RunoffThe physical geology and topography of the ground as well as meteorological conditions all have an impact on surface runoff. Only approximately a third of precipitation that falls on land drains into rivers and streams before being dumped back into the ocean. The remaining two-thirds either evaporate, transpire, or soak into the earth (infiltrate). Humans have the ability to redirect surface runoff for their own purposes.More and more of the natural environment is being replaced by impermeable surfaces, such as roads, homes, parking lots, and buildings, which decrease groundwater infiltration and hasten runoff to ditches and streams as more people inhabit the planet and as development and urbanization increase.To learn more about Surface Runoff refer to:

What typically happens to the size, shape, and sorting of clasts as they are transported from steep mountains toward more gentle settings?
The clast become more rounded as they are transported from steep mountains toward more gentle settings.
The clasts make up 20-30% of rocks. Tumbles, bumps, and wear during transportation may reduce the size of the clast, increase its roundness, and cause the clast to be sorted by size. As sediments are transported and deposited, they leave evidence of modes of transport and deposition.
For example, when a vehicle slides down a slope, the resulting sediments are generally chaotic and have varying grain sizes. Grain size and the interrelationship between particles gives the resulting sediment texture. Clasts are classified by density based on the energy of the transport medium. High-energy currents can transport larger fragments. As the energy decreases, heavier particles are deposited and lighter debris is transported further.

In the accompanying diagram, mLC = 90, mLA = 42, and CA = 10. Which equation can be used to find AB? C 10 42° A
Option D. If mLC = 90, mLA = 42, and CA = 10, the equation that can be used to find AB is [tex]cosine 42 = \frac{10}{AB}[/tex]
How to find ABWe have to find the the way to solve the right angled triangle we have here.
We have the angle at point A.
We have to make use of SOH CAH TOA rule
We would use
Cosine = adjacent / hypotenuse
adjacent = the value 10
The hypotenuse is = AB. This is the sign that is facing the angle.
We would then have the equation to be
Cosine 42° = 10/AB
[tex]cosine 42 = \frac{10}{AB}[/tex]
We can proceed to find AB
To get the value of AB
AB cosine 42 = 10
AB0.7431 = 10
AB = 10/0.7431
= 13.46
The value of AB = 13.46, But the questions only asked us to fing the equation. Hence option D is correct.

The contribution margin is first used to cover fixed expenses. Once the break-even point has been reached, the contribution margin becomes profit.
What Is Contribution Margin?The contribution margin may be expressed as a gross or per-unit figure. After the variable element of the company's costs are subtracted, it indicates the additional revenue made for each product or unit sold.
The selling price per unit less the variable cost per unit is used to calculate the contribution margin. The measurement, also known as dollar contribution per unit, shows how a specific product affects the company's overall profit.
How is Contribution Margin Calculated?
The difference between a product's sale price and the variable costs related to its manufacturing and selling process is calculated as the contribution margin.
Revenue minus Variable Costs equal contribution margin. The contribution margin ratio is computed as (Revenue - Variable Costs) / Revenue.
