Question

Metal ores are often formed in locations that had volcanic activity in the past. What information about an area would provide the best evidence that metal ores could be found there in the present?

A) Evidence that metal ores had been brought to the area by ancient humans
B) Evidence that the area had active volcanoes long ago
C) Evidence that humans in the area use lots of metal ores
D) Evidence that volcanoes in the area are currently active

Answer 1

The best evidence that metal ores could be found in an area in the present is evidence that the area had active volcanoes long ago.

Step-by-step explanation:

The best evidence that metal ores could be found in an area in the present is evidence that the area had active volcanoes long ago (option B). Metal ores are often formed in locations that had volcanic activity in the past because volcanoes release magma, which can deposit minerals rich in metals as it cools and solidifies. This process can lead to the formation of metal ores. For example, copper ores are commonly found in areas that had volcanic activity because copper is often associated with volcanic rocks.
