Scientists can tell the average temperature of the earth by studying an ice core.
true
false

The given statement is true.

Explanation:

The given statement that is the scientists can determine the usual temperature of the Earth by reviewing an ice core is correct. By evaluating and studying the ice cores, scientists become familiar with the changing atmospheric levels of carbon dioxide, about the glacial-inter-glacial cycles, and the stability of the climate over the past 10000 years.  

It also allows scientists to determine the past modifications in both the atmospheric concentrations of greenhouse gases and temperature.  

it would be the percentage of food eaten by the flock
