Answer:
Erosion is the washing away of the uppermost part of the earth crust. Once erosion starts it only gets worse because, erosion wash away further soil, causing the eroding channel to futher expand, increasing the erosion.
Lack of vegetative cover allows erosion which washes away soil nutrients, further worsening the soil against soil vegetative cover.
Answer:
density = 0.822 g/mL
Explanation:
We calculate the density knowing the flowing formula:
density = mass / volume
mass = 2.98 grams
volume = 21.1 × 14.2 × 12.1 = 3625 mm³ = 3.625 cm³ = 3.625 mL
density = 2.98 / 3.625 = 0.822 g/mL
The pH of the solution is 4.
<h3>What is pH value ?</h3>
pH value is the measure of the acidity and basicity of a solution.
It measures the [H+] ion liberated by an acid when dissolved in a solution.
It has a range of 0 to 14 , where 0 to 6.9 indicates acidity , 7 represents neutral solution , More than 7 up to 14 indicates alkaline solutions.
pH value is also used to predict the completion of a reaction .
It is given in the question that
The value of pOH = 10
pH = ?
It is known that the sum of pH and pOH is equal to 14.
pH + pOH = 14
pH + 10 = 14
pH = 4
Therefore the pH of the solution is 4.
