Use the graph to answer the question. The vertical axis is labeled millions and ranges from 0 to 900 in increments of 100. The horizontal axis is labeled year and lists dates from 1700 to 2000 in 100-year increments. The line for population starts at 90 million for 1700 and with a slow growth rate reaches to 120 million by 1900. The line then rises with a high growth rate and reaches beyond 600 million by 2000. The line for steel consumption starts from 0 in 1860 and reaches 20 million by 1900. The line then rises with a high growth rate to reach beyond 800 million by 2000. The values used in the description are approximate.

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

(1 point)

Steel consumption increased when people started to use computers.

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

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

A larger population consumes greater amounts of fossil fuels like steel.

When mining occurs, what is a significant direct impact on the environment?(1 point)

More construction can happen with the metals that are mined, which can disrupt new ecosystems.

Fossil fuels burned during mining release carbon dioxide, leading to ocean acidification.

Habitat is removed for wildlife that used the hills and mountains where mines are built.

There are more resources used to recycle the metals that are mined.

Which energy source releases the most carbon dioxide?(1 point)

solar

wind

nuclear

coal

If there is an increased level of carbon dioxide in the atmosphere, what happens to infrared radiation released by the Earth?(1 point)

It is converted to solar energy

It escapes and cools the atmosphere

It is converted to carbon dioxide

It is absorbed and heats the atmosphere

With such huge increases in population, why has there not been a direct and equivalent increase in urban development (i. e., why is it such a small proportion of habitable land use)?(1 point)

People want to live close to where they work, which is usually the city or suburbs.

Habitable land is already being used for livestock and crops.

There is not enough habitable land left for further urban development.

Many people can live in small spaces, such as high rises in cities.

In almost all chains of consequences, what happens over time as the consequences unfold?(1 point)

Consequences spread through the area like a ripple effect, starting in the center and radiating outward.

Consequences increase in size and scale and become longer lasting.

Consequences travel from one type of habitat to another, until multiple habitats are affected.

Consequences decrease in size and scale and become short term.

Which change over time in Landsat maps would most likely be associated with contaminated water habitats nearby?(1 point)

gray areas replaced with light green areas

green areas replaced with yellow areas

increased size of dark green areas

increased size of gray areas

Which human activity can result in the heat island effect?(1 point)

using habitable land for pasture land

covering the ground with concrete and pavement

building green spaces and roof gardens

converting forest to agricultural land

I will give brainliest to whoever give all answers
