Question

visual literacy: reading graphs
pages 551 - 553 of your textbook show several line graphs about climate change.
remember that graphs show data in a visual way and make it easier for us to see and
interpret information. being able to read and understand graphs is an important skill.
examine the line graph below from page 551 of your textbook and answer the questions that follow.

1. what does this graph show? use the labels to help you.

1. what information is shown along the x - axis? recall that the x - axis is the horizontal axis.

1. what information is shown along the y - axis? recall that the y - axis is the vertical axis.

1. what happened to the temperature between 140,000 and 130,000 years ago?

1. how did temperature change from about 100,000 years ago to about 20,000 years ago?

1. what is currently happening to the temperature on earth?

Explanation:

1. The graph shows the relationship between time (years before present) and temperature change.
2. The x - axis shows the number of years before the present.
3. The y - axis shows the temperature change in degrees Celsius.
4. Between 140,000 and 130,000 years ago, the temperature increased.
5. From about 100,000 years ago to about 20,000 years ago, the temperature fluctuated but generally decreased.
6. Currently, the temperature on Earth is increasing.

Answer:

1. The relationship between time (years before present) and temperature change.
2. The number of years before the present.
3. The temperature change in degrees Celsius.
4. The temperature increased.
5. The temperature fluctuated but generally decreased.
6. The temperature is increasing.
