Some estimates put the first human settlements in the Amazon at 32,000 to 39,000 years ago. Since that time, Amazon people have developed lifestyles that are well integrated with the benefits and constraints of rainforests.
An estimated 7-10 million Amerindians (the term for American Indigenous peoples) lived in American rainforests, half of them in Brazil, at the time of European arrival. When Pizarro arrived in Peru, more land was under cultivation and more food was being produced in the Andean region than today.
Answer:
Movement of people between places on a regular basis → cyclical migration
Study of population → demographics
average number of children a woman will have in her lifetime → fertility rate
the number of people who live in a square mile or kilometer → population density
people who leave their homelands seeking safety in a foreign country → refugees
Explanation:
Migration is the movement of people from from one place to another. A cyclical migration is a kind of movement that is a routine and are usually short.

Answer:
zenith distance = 39 degree
Explanation:
given data
declination of star = -13.00º
latitude = 26.00º N
to find out
distance in degrees between the star and zenith
solution
we know the formula that is
latitude = star declination+ its zenith distance ....................1
and
zenith distance = latitude - star declination
zenith distance = 26 - ( -13 )
zenith distance = 26 + 13
zenith distance = 39 degree
