Science 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. 48 degrees, I don't know why I put this I just thought it was a good guess.
• 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? No not alot, I say at least 1 degree because it takes a long time for the globe to change its overall temperature.
• 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 temperature would have to be at least 600 degrees and the coldest would have to be -135 degrees I picked these because the earth was once molten and I think the coldest would be this cold because the earth has gone through many ice ages.
• 4 - Are you concerned about "global warming?"  Why or why not? Well I'm about half and half because I think the concept of global warming is exaggerated a little bit, but I do think that we need to clean our act up or global warming could be a very serious problem one day.
