Question

Which of the following properties of water help to explain why icebergs float in the ocean?

Icebergs are composed of freshwater and freshwater is less dense then salt water.

Icebergs are composed of freshwater and freshwater is more dense then salt water.

Icebergs are colder then the ocean water and cold water is less dense then warm water.

Icebergs are colder then the ocean water and cold water is more dense then salt water.

Answer 1

Icebergs are composed of freshwater and freshwater is more dense then salt water.

Answer 2

Icebergs are made of fresh water, yes.

But fresh water is actually LESS dense than salt water.

Answer 3

No u r wrong @InYourHead we learned this in our AP BIOLOGY class and i got correct in my quiz

Answer 4

This article tells us that fresh water is less dense than salt water.

This article also tells us that fresh water is less dense than salt water, in the second-to-last paragraph.

Oh, look! That last article even talks about why icebergs float! How relevant to our question!

You're in AP Biology, but you don't remember ever having done any water density experiments? In elementary school?

Just take another look at the second link that I've posted.

I thought that all kids had done experiments similar to that one, by the end of elementary school.
