What was NOT one of Wegener's 4 pieces of evidence of Continental Drift? Question 2 options:

The coastlines fit together like puzzle pieces

Divergent boundaries causing sea-floor spreading

Same fossils show up on different continents

Different continents had the same ancient climates

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
