Answer:

removes the fertile B horizon of soil

Explanation:

Wind erosion has the capacity to remove the fertile B horizon of the soil.

The term wind erosion generally refers to the capacity of high-magnitude wind to cause damages to the terrestrial environment. Soils can get their topmost layers removed by a strong wind if there are no barriers such as vegetation to break the speed of the wind.

The topmost layers in most cases consist of humus and the fertile minerals from parent materials. When the topmost layer is lost, the soil becomes unproductive for agriculture.

At which location in Earth's interior exhibits a change in

uranmaximum [27]

Answer:

The Earth's interior exhibits a change in trend in the "outer core."

Explanation:

The 4 Main Layers of the Earth

1. Crust - This is the outermost layer of the Earth. It consists of igneous, metamorphic and sedimentary rocks. This makes the crust rock solid.

2. Mantle - The mantle is formed by silicate rocks. It is located between the crust and the outer core. It consists of the upper mantle and the lower mantle. The upper mantle lies between the crust and the lower mantle while the lower mantle lies between the upper mantle and outer core.

3. Outer Core- This is the only liquid layer of the earth. It is mostly made of iron and nickel. This causes a change in trend among all the other parts of the Earth which are solid.

4. Inner Core- This is the innermost part of the Earth. The temperature here is hotter than the sun. The solid inner core is said to be growing at the expense of the outer core. This also has the highest density of all.

Answer:

$\boxed{\text{(a) 14 L; (b) 711 kg}}$

Explanation:

(a) Litres of water

$\text{Mass of F}^{-} = 8.5 \times 10^{7}\text{ gal} \times \dfrac{\text{0.2 mg F}^{-}}{\text{1 kg}} = \textbf{14 mg F}^{-}\\\\\text{Volume of water} = \text{14 mg F}^{-} \times \dfrac{\text{1 L water}}{\text{1 mg F}^{-}} = \textbf{14 L water}\\\\\text{The person would have to consume $\boxed{\textbf{14 L}}$ of water per day}$

(b) Mass of NaF

$\text{Volume} =8.5 \times 10^{7} \text{gal} \times \dfrac{\text{3.785 L}}{\text{1 gal}} = 3.22 \times 10^{8}\text{ L}\\\\\text{Milligrams of F}^{-} = 3.22 \times 10^{8}\text{ L} \times \dfrac{\text{ 1 mg F}^{-}}{\text{1 L}} = 3.22 \times 10^{8}\text{ mg F}^{-}\\\\\text{kilograms of F}^{-} = 3.22 \times 10^{8}\text{ mg F}^{-} \times \dfrac{\text{1 mg F}^{-}}{10^{6}\text{kg F⁻}} = \text{322 kg F}^{-}$

1 kmol of NaF (41.99 kg) contains 19.00 kg of F⁻.

$\text{Kilograms of NaF}= \text{322 kg F}^{-} \times \dfrac{\text{41.99 kg NaF}}{\text{19.00 kg F}^{-}} = \text{711 kg NaF}\\\\\text{It will take } \boxed{\textbf{711 kg}} \text{ of NaF to treat the reservoir}$
