Fill in the table below based on the global temperature record:

Time period Number of years with mean Temp. > 0° to +1° above mean Number of years with mean Temp. more than +1° above mean Number of years with mean Temp. < 0° to -1° below mean

1880-1899 0 0 20

1900-1919

Have global temperatures risen or fallen since 1900, and how much have they changed (how many temperature degrees) .

What is the size of the overall temperature changes in USA (how many degrees has it changed, see previous graph!) and how does this compare to the size of the global temperature change calculated in the previous question?

Are the years with the highest and lowest annual temperatures the same on both graphs (are the same in the USA versus in the world)? If not how much do they differ?

Are the points with the highest and lowest 5 year average temperatures the same on both graphs? If not how much to they differ (i. e. how much time is there between them)?

Suggest a reason why mean annual temperature in USA may differ from mean global temperature. (Hint: think about USA’s geographic position on earth, how is USA different from the average values you would get looking at all of earth, what’s special about it)

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?
