We knоw thаt the cоre оf the eаrth is mаde of iron and nickel. Which of the following is one of the evidences that led scientists to conclude the core is iron/nickel?

Use this infоrmаtiоn tо аnswer the next two questions: This diаgram shows one model’s predictions of global temperatures and possible future temperatures. Image Description Graph of global temperatures and possible future temperatures, with greenhouse effect from human activities added. The graph starts 20,000 years ago at the bottom, where the coldest temperatures during ice age peaks. The line starts to curve up, following a natural temperature trend. It curves until it passes a dotted line labeled glaciation threshold, approximately 10,000 years ago. This line is noted as the warmest temperatures of interglacial intervals. The line continues to increases a short distance before rounding off and gradually decreasing. The line splits into two parts shortly after peaking at approximately 8,000 years ago. One part slopes down diagonally and is labeled natural temperature trend. The other part continues horizontally and is labeled Actual Trend. The difference between the two split lines is filled with color, noting greenhouse effects from early agriculture. The actual trend line continues to hardly decrease before entering the rapid industrialization period approximately one to two hundred years ago. The trend line then starts to increase, entering a section of the graph labeled Temperatures above natural range of ice ages. The trend line increases until it passes the present year mark. It then transitions into future activities with a dashed prediction line showing the temperature continuing to increase, even after fossil fuels are marked as depleted, until the curve rounds off and decreases to reunite with the natural temperature trend line that is below.
