How did the geography and climate of the ice ages differ from today?

First of all, climate of the ice ages was like the ice layers of Greenland and Antarctica all over (meaning freezing cold), that's one of the main differences, and it was more variable than the warm and stable climate we have these days. Besides continental sheets were expanded occupying vast more areas, and off-course less agricultural land available, so the continents shape were extremely different.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !

the answer is a quran
