Answer:
Glomar Challenger studies about the "age of rocks in various places in the ocean" in 1968
Step-by-step explanation:
Glomar Challenger was a "deep sea research vessel" for marine geology and oceanography studies.
The vessel set out in 1968 on a "Deep Sea Drilling Program" in the Atlantic Ocean.
Samples were collected from various drilling locations and the study and analysis of these samples enabled the study of plate tectonics.
These samples also provided more information related to the rocks in oceans.
The vessel drilled cores containing rock salt, gypsum, anhydrite and several other evaporating minerals.
