Question

glaciers are masses of ice that hold important information about earths past. by studying glaciers, scientists can see what temperatures used to be like and how the amount of so - called \greenhouse gases\ has changed. unfortunately, earth is getting warmer, and glaciers have started melting. to prevent the loss of important data, in 2015, scientists collected ice samples from a glacier in the french alps. the team used special drills to extract ice cores that were more than 130 meters long. because the cores were so large, they needed to be brought up in segments. the scientists faced another challenge—finding a place to store the cores where they would remain safely frozen. some of the cores were taken to concordia research station in antarctica. the rest were shipped to other research centers around the world. match the problems with their solutions. the samples were brought to the surface in sections. the samples were taken to antarctica. the samples were extracted. problem solution glaciers started to melt. the samples were huge. the samples had to be preserved.

Explanation:

• For the problem "Glaciers started to melt", the solution is to extract the samples (so that the important data in glaciers can be preserved).
• For the problem "The samples were huge", since they were more than 130 meters long, the solution is to bring them to the surface in sections.
• For the problem "The samples had to be preserved (remain safely frozen)", the solution is to take them to Antarctica (a cold place where they can stay frozen).

Answer:

• Problem: Glaciers started to melt. Solution: The samples were extracted.
• Problem: The samples were huge. Solution: The samples were brought to the surface in sections.
• Problem: The samples had to be preserved. Solution: The samples were taken to Antarctica.
