Answer 1

The correct answers are:

1) Ice formed thousands of years ago
2) Chemical isotopes in foraminifera shells

Answer 2

tree rings

Answer 3

I apologize for the mistake in my previous response. Tree rings are indeed studied by scientists to determine past climate conditions and infer air temperature at the time the tree rings were formed. Therefore, the correct answers are:

1) Ice formed thousands of years ago
2) Tree rings
