Question

[122]. Read the following passage carefully:

Passage: "A glacier moves so slowly that it seems still, yet over years it carves valleys and carries rocks for miles. Its ice, formed from compressed snow, flows under its own weight, cracking and groaning as it moves. When a glacier melts faster than snow adds to it, rivers downstream first swell and then may shrink, affecting farms and towns. Scientists measure glaciers not only to study ice but to understand water for the future. A glacier, therefore, is not a frozen relic; it is a slow river of ice whose balance shapes water security." What is the main idea of the passage?

1.
Melting glaciers only increase rivers forever.
2.
A glacier is a slow river of ice whose melting balance shapes downstream water security for farms and towns.
3.
Glaciers never move.
4.
Glaciers are frozen relics.
