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 extracted.
the samples were brought to the surface in sections.
the samples were taken to antarctica.
problem
glaciers started to melt.
the samples were huge.
the samples had to be preserved.
solution

Explanation:

• For "Glaciers started to melt", the solution is extracting ice samples to prevent data loss.
• For "The samples were huge", since they were large, bringing them up in segments (sections) is the solution.
• For "The samples had to be preserved", taking them to Concordia Research Station in Antarctica (where it's cold to keep them frozen) is the solution.

Answer:

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