Which list shows the planets in order from the least diameter.

to the greatest diameter.

CLEAR ALL

Mars, Earth, Neptune, Saturn

Step-by-step explanation:

Planets                   Mars,       Neptune,        Earth,      Saturn

Diameter (km)        6770         49244             12742     116460

The least diameter is of mars, then is of the earth, then Neptune and the greatest in the list is of Saturn.

The list of least to greatest would be

Mars, Earth, Neptune, Saturn

The mars is farther to the sun as compared to the earth. As the planet moves away from the Sun it's orbit becomes bigger and bigger. Neptune is the eigth planet and saturn is the sixth planet.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
