Question

earths average temperature has risen over the past century. most of this rise is because certain gases released into the atmosphere by humans. this rise in average temperature caused by humans is known as global warming.
this graph shows earths average temperature change between 1900 and 2015. the temperature change for each year is the difference between the average temperature in that year and the average temperature in 1900. the data come from averages of measurements taken at weather stations around the world.
temperature change since 1900
complete the sentence.
based on this graph, earths average temperature increased by about between 1900 and 2000.
0.5°f
1°f
1.5°f
2°f

Explanation:

Step1: Locate the temperature change in 1900 and 2000

In 1900, the temperature change is near \(0^{\circ}F\). In 2000, the temperature change is near \(1^{\circ}F\).

Step2: Calculate the increase

The increase is \(1 - 0=1^{\circ}F\)

Answer:

\(1^{\circ}F\)
