Definition: To mine using the technique of hydraulic mining.

Alright class, settle down, let’s take a look! That definition you read – “To mine using the technique of hydraulic mining” – gives us a good starting point. But what does hydraulic really mean? It's more than just digging with water, you see! Let’s break it down in a way that makes sense: "Hydraulic" comes from the Greek word "hydro," which means “water.” Think of words like "hydrate" – it’s all about water! So, ‘hydraulic’ describes something powered by pressure and movement of liquid, usually water. It's about force being transferred through a fluid. Now, let’s connect that to hydraulic mining. Hydraulic mining used powerful pumps to blast away mountainsides with high-pressure jets of water. The water acted like a giant shovel, washing away the soil and revealing the precious minerals underneath! Here's a little rhyme to help you remember: "Hydraulic is flowing, forceful and free, Powered by liquid – for all to see!" Does that make sense? Do you have any questions about what ‘hydraulic’ means beyond just mining? Let’s discuss!
