Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen on the graph?

Whenever the population has increased, steel consumption has increased as well

A larger population consumes greater amounts of fossil fuels like steel

When the population first started to increase, there was a need for much more construction

Steel consumption increased when people started to use computers.

A. Whenever the population has increased, steel consumption has increased as well.

Explanation:

Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen  on the graph is that whenever the population has increased, steel consumption has increased as well.

A critical look at the graph, you will discover that the population and the steel consumption are moving upwards (i.e they are increasing). It's seen that as the population increases, steel consumption increases. This is true because as the population increases, people are building houses, more transportation systems that require steel are being manufactured, more household utensils that are steel products are being fabricated etc; therefore the consumption of steel increases.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

lol idk man i guess u gotta ask bill nye the science guy
