Global Temperature

The horizontal scale of this graph starts at 0 and goes to 2,000. Each tick mark represents 100 years. This graph shows 2,000 years.
The vertical axis is showing temperature anomaly in celsius. The total range is -0.8 to 0.8.
The graph came from UAH Globally Averaged Satellite-Based Temperature of the Lower Atmosphere. 

1. I think the global average temperature is the average temperature all over the globe. I answered what I did because of using context clues.
2. I guess a random guess for the amount that the global average temperature has increased is 100-175º (random guess) I guess it is a lot when you are thinking about how hot that is.
3. I don't even have a guess as to how hot the earth has gotten before. Umm I guess the coldest it has been could be -70º (random guess) I answered what I did because I have a pair of hunting gloves that say that they can keep your hands warm in -40º. I mean they can obviously lie about that to make them sound better, but it was just a random guess.
4. I'm really not worried about global warming at all. a) because I really don't know anything about it. b) because I'm not a polar bear. Buuuuut I really don't know anything about it, so I'm really not sure what I'm talking about at all.

Forest Soil/Grassland Soil

Forest Soils need moderate amounts of rain. They need enough rain to support tree growth and to help with crops. You find this soil where weather is usually warm and humid year round. Grassland Soil needs just enough rain to support grass and is found in dry places. Grassland soil is found in places where it is warm all year. It is also found places where there are wet and dry seasons. This soil is also fertile enough for growing crops.
