A Line Graph
a line graph
I don't know what visual model is, but 1/2 + 3/16 = 11/16 .
A line graph would show this.
A line graph is used to display data or information that changes continuously over time. Line graphs show overall trends such as an increase or decrease in data over time. In this case, it would show a change in air temp over a long period of time.
Area
a line graph
A map showing the changes in areas covered by ice over time. APEX

you would expect that the populations of animals are increasing or decreasing or because of no rainfall the plants will get dried.
A visual aid of data is giving an example or showing your data in picture or visual form. "I'm going to take over the world!" So you would have a picture of the Earth or showing us how your going to do it.
Scientist
if it did know what it was doing then no but if it did not know better then yes.
months* I think the best choice would be a line graph since line graphs are known to display data that changes over time. In your question the mass probably changes throughout an owl's life. This info would show clearly in a line graph since the mass changes.
it just goes down because of weathering
Fossil evidence would indicate change over time.
Data gathering
The mixing of different people caused changes. English is a combination of a lot of different languages put together over time.
