Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the best reason for scientists to study ice cores obtained from Earth’s ice caps?
A
to evaluate potential oil drilling sites
B
to study the quality of water stored in glaciers
C
to determine the rate of melting in polar regions
D
to study past climates by analyzing trapped gases and particles
Explanation: 

Detailed explanation-1: -They collect ice cores in many locations around Earth to study regional climate variability and compare and differentiate that variability from global climate signals. The samples they collect from the ice, called ice cores, hold a record of what our planet was like hundreds of thousands of years ago.

Detailed explanation-2: -Ice cores provide direct information about how greenhouse gas concentrations have changed in the past, and they also provide direct evidence that the climate can change abruptly under some circumstances.

Detailed explanation-3: -Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patternsIce cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns.

Detailed explanation-4: -Through analysis of ice cores, scientists learn about glacial-interglacial cycles, changing atmospheric carbon dioxide levels, and climate stability over the last 10, 000 years.

Detailed explanation-5: -Examining the gasses trapped in ice cores is how scientists first learned that the amount of carbon dioxide and the global temperature have been linked at least the last million years of Earth’s history.
