Answer:
The correct option is A) It is not written by an authority
Explanation:
In the English language, credibility can be described as the quality of an object to be reliable or trusted.
A piece of written work which does not mention the name of the writer may be considered to be not reliable and trustworthy. Hence, the correct option is A.
Other options, like option D, is not correct because a peer- reviewed journal carries authentic information as the work has been rechecked by different people who have expertise on the subject.
Answers are in bold.
1. Energy from the sun is transferred to Earth's surface. Some of that energy is then transferred to the air above the surface.
2. The closer a location is to the equator the more energy it receives from the sun. Therefore a location's air temperature is affected by its distance from the equator.
3. An effect may have more than one cause. These may be linked into a chain of causes and effects.

It helps to make scientific inquiries
Explanation:
Environmental science is a broad discipline which includes geology, physics, biology etc.
The nature of inquiries is often scientific. The procedures to follow in making useful deductions about environmental phenomenon must be guided scientifically.
Scientific methods is a systematic approach in which scientists can gather facts. Through their numerous observations, they formulate a sort of scientific guess called an hypothesis. Hypothesis can be tested over time and theory springs up. These theories can then be applied to tackle various related scientific puzzles.
Ionic compounds:
•Have molecules that consists of charged ions and these ions have positive and negative charges.
• ionic compounds are formed by electrical attraction of two of more ions
• ionic compounds have a high melting & boiling points
• the bonds of ionic compounds are crystal like
• can conduct electricity in water
Covalent compounds:
• they are non metals bound together & consist of two electrons shared between two atoms
• formed when two non metals bound together
• they have lower melting and boiling point
• they easily separate because they are formed from distinct molecules that don’t bond together
• covalent compounds are softer and more flexible
• covalent compounds cannot conduct electricity under water because they are non polar
