Which allows scientists to investigate what Earth’s climate was like over the past 740, 000 years?
A
volcanic deposits
B
fossils
C
faults
D
ice cores
Explanation: 

Detailed explanation-1: -Paleoclimatology is the study of the climate history of Earth. This science helps people better understand the climate of Earth in the past and how it relates to the present and future climate on the planet.

Detailed explanation-2: -Scientists can use both sea-floor sediment and ice cores to study climates that existed hundreds of thousands of years ago. They can compare evidence from each method to see if both agree about the climate of a particular period.

Detailed explanation-3: -Clues about the past climate are buried in sediments at the bottom of the oceans and lakes, locked away in coral reefs, frozen in glaciers and ice caps, and preserved in the rings of treesTo extend those records, paleoclimatologists look for clues in Earth’s natural environmental records.

Detailed explanation-4: -Scientists often use ice cores to detect changes in temperatures. When snow falls it traps air into the ice. When scientists take a core of ice it reveals the atmospheric gas concentrations at the time the snow fell. This is used to calculate temperature at that time.

Detailed explanation-5: -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.
