Answer:
pollution and overpopulation
Answer:
There are many causes of soil degradation in Ethiopia, but the main ones are deforestation, overgrazing, and poor farming practices. Deforestation leads to loss of topsoil, which is essential for plant growth, and also exposes the underlying rocks to erosion by wind and water. Overgrazing can also lead to loss of topsoil, as well as compaction of the soil, which makes it harder for plants to grow. Poor farming practices, such as not rotating crops or using too much pesticide, can also lead to soil degradation.
Explanation:
I think it be, option b. weather of the day
Answer:
D
Explanation:
The solution to the problem is 
How did we arrive at this:
We are going to use trigonometric ratios to solve this problem. The diagram of the sail forms a perfect and unique right angle triangle.
From the diagram, we can easily decipher the:
- hypotenuse axis
- opposite axis
- adjacent axis
From the given diagram, we know:
Adjacent axis and the opposite angle;
tan Ф = 
The unknown axis faces the opposite side;
Opposite = adjacent x tan Ф
Opposite = 2 x tan Ф
Note;
tan Ф = 1/ cot Ф
opposite = 2 x 1/ cot Ф
when Earth makes half of a full rotation starting with noon time of spring day, there will be midnight on completion. Thus, option C is correct
<h3>What do you mean by rotation?</h3>
When the earth revolves around its own axis, rotation takes place. This will result in changes day and night. Earth takes 24 hours to complete a rotation on its axis.
When earth revolves around the sun it is called revolution, due to which a year got changed. Earth takes 365 days to complete a revolution.
Therefore, option c when the earth makes a rotation at noon and completes its half-cycle clearly shows midnight.
