Final Answer:
Option 4: Almost 50% of the major types of minerals found in Australia are not found in the United States.
Step-by-step explanation:
Upon analyzing the chart depicting the major types of minerals mined in the United States and Australia, it is evident that Australia has a more diverse range of minerals compared to the United States.
Specifically, approximately half of the major types of minerals found in Australia are not found in the United States. This conclusion is drawn by observing the distribution of minerals between the two countries on the chart.
The chart provides a visual representation of the types of minerals in both countries, and by calculating the proportion, it becomes clear that the statement in Option 4 is accurate. The diversity in mineral resources is a crucial factor in understanding the comparative advantages and economic activities related to mining in each country.
