Answer 1

What's your best guess?

Answer 2

Think of the graph as representing height with time moving to the right. So the first graph represents that there's a lot of stuff, but over time the amount of stuff goes down gradually over time.

The second one represents that something increases slowly then decreases slowly over time, this makes sense that it represents temperature during the day because the sun comes up and heats up the place and then when the sun sets things cool down. Does that make sense?

Answer 3

Yup in the morning temperature is low... then it gradually increase and then in the evening it decreases.
