Your friend Angela tells you about a field trip that she went on and learned about mining. She and her classmates had the opportunity to harvest minerals from a local river. They used pans to scoop the materials from the water and washed and shook the pans to separate the minerals from rocks and other debris. Unfortunately, she and her classmates were not allowed to keep souvenirs. What type of mining did Angela and her classmates participate in? (1 point)
Angela and her classmates participated in placer mining.
From the given information, Angela and her classmates were using pans to scoop minerals from a river and separating them from rocks and debris. Based on this, it is evident that they were practicing placer mining. Placer mining involves extracting minerals (such as gold, gemstones, or other valuable materials) from alluvial deposits, such as riverbeds or stream sediments, by washing and shaking them in pans or sluices to separate the heavy minerals from the lighter materials. So, the correct answer is placer mining.
