in demographics, process whereby you divide 70 by the population growth rate to estimate how many years it will take for the countrys population to double

35. recession
loss of jobs+ less money spent because of bad economy
36. What are the winds that influence us in summer, winter?
• winter= jet stream pulls down cool arctic air
• summer= jet stream pulls up warm gulf air
37. What are the two currents that collide to make fog?
Cold Labrador current and Warm gulf stream
38. mt, mp,ma, ct,cp,ca
• maritme= wet(formed over water)
• continental= dry(formed over land)
• Ploar=formed between 55N and 66N
• Artic= very cold, formed over arctic
