Scientists collect data regarding earth's surface temperature over the last 900,000 years using direct and indirect methods. if they construct a graph of this data, which statement best describes the graph? need
a the graph would have a fairly straight line with a sharp curve upward to show recent rising temperatures.
b
the graph would show stable temperatures followed by a sharp curve down as temperatures cooled.
c
the graph would start low, and then curve upward significantly to show a rapid rise in average temperatures.
d
the graph would have both highs and lows to show the periods of warm and cool temperatures.
