Global Temperature Graph

1. The horizontal scale is by 20 years. It is showing the years 1880-2000.
2. The vertical axis is showing the temperature anomaly. It goes up by .2. The total range is -.4 to .6.
3. I can tell that it came from a school website on their assignments.

Questions

• 1 - What do you think the global average temperature is?  This means the average for everywhere on Earth, day and night, for an entire year.  Explain why you answered what you did.
• I think it would be 50 degrees because for the most part, half the areas of the earth are really really cold and the other half is really really hot or some areas are in between.
• 2 - People are often talking about "global warming."  How much do you think the average global temperature has increased in the past 100 years?  Do you think that this is a lot?
• I think it has increased around 20 degrees. I think this is a lot because 20 degrees can make a big difference. 
• 3 - What do you think is the hottest the Earth has ever been? (since there has been an atmosphere?)  How about the coldest the Earth has ever been?  Explain why you answered what you did.
• I think the hottest it has ever been is around 150 because in some places the earth is realllllyyyyyyyy hot. I think the coldest it has ever been is around -50 or -50 degrees because it's like that in Antartica.
• 4 - Are you concerned about "global warming?"  Why or why not?
• Yes, because the ice caps are melting which is causing the ocean to rise which means some places will be underwater.

Question 4

The amount of rainfall shows how it can affect the types of soil because of the wet or dryness. In forest soils, the soil is shallow. But in grassland soils, the soil is much deeper. This is because the climate is very hot in the grasslands and doesn't have much rain. So, the rocks weather faster. In the forest lands, there is much more rain and isn't hot year round so it doesn't weather down as easily.
