Fog can form through each of the following ways EXCEPT Question 7 options:
Schach [20]

Answer:

The correct answer is the letter D. decreasing the moisture content of the air and increasing temperature

Explanation:

Fog is the result of air humidity, or water vapor in the atmosphere. The mist that forms in the morning is the result of water that changes from a gaseous to a liquid state. It is characterized by a cluster of water droplets, which give rise to a type of cloud that is very close to the Earth's surface arising from the cooling of the air during the night. Thus, it is formed by the suspension of water droplets in an air layer close to the ground. Thus, fog can be considered a cloud that comes into contact with the ground.

The aspect from which a sample is drawn is known as the
PolarNik [594]

We use samples to perform experiments. When sampling, we take test subjects from a larger group often known as "<em>population</em>" or at times "<em>universe</em>".

Sampling is a term we use to describe the process of selecting a small representitive group from a larger population. Sampling can often be divided in its simplest form into:

  1. <u>Random Samples</u>
  2. <u>Non-Random Samples.</u>

Which as their names imply, represent first a sample that is chosen by not specific method and whose probability is equal for the entire <em>population</em>, and secondly a sample chosen based on specific parameters.

Sampling can then become more complex, being divided into more complex methods such as:

  • <u>Systematic sampling </u>
  • <u>Stratified sampling </u>
  • <u>Cluster sampling</u>

etc.

The one thing all of the sampling methods have in common is the fact that they will all draw their samples from one place. This place or aspect from which samples are drawn is known as the <em>population</em> <em>group </em>or sometimes coined as the <em>universe</em>, to represent the group in its entirety.
