Question

Select the correct answer. scientists at russia’s vostok station in eastern antarctica drilled the longest ice core ever recorded. they compiled this graph using the data collected from the ice core. this plot shows the temperature, carbon dioxide (co₂), and dust levels up to 400,000 years ago. which statement best summarizes the data in the graph? a graph showing temperature, carbon dioxide, and dust levels analyzed from ice cores drilled from vostok station in east antarctica

a. spikes in the dust concentration represent interglacial periods, and troughs represent glacial periods.
b. airborne dust concentrations have steadily increased from 400,000 years ago to the present.
c. air temperature and atmospheric co₂ concentrations illustrate a negative correlation.
d. an increase in the air temperature and co₂ levels corresponds with a decrease in dust concentration.

Answer 1

The graph shows a negative correlation between air temperature and atmospheric CO₂ concentrations.

Step-by-step explanation:

The graph compiled using data collected from the ice core drilled at Russia's Vostok Station in Eastern Antarctica shows temperature, carbon dioxide (CO₂), and dust levels up to 400,000 years ago. The best statement summarizing the data in the graph is option C: air temperature and atmospheric CO₂ concentrations illustrate a negative correlation.
