Conversation

Did you know that quartz has an orthorhombic structure?

Really? I always thought it was just a regular crystal.

Yeah, it's fascinating how different minerals can have such unique forms, like the orthorhombic system.

I guess there's a lot more to learn about crystals than I realized!

Synonyms & Antonyms

Root Explanation

Orthorhombic → It is formed from "ortho-" (from Greek "orthos", meaning straight or correct) and "rhombus" (from Greek "rhombos", meaning a shape with equal opposite angles). The term describes a crystal system characterized by three mutually perpendicular axes of different lengths, reflecting the idea of straightness and symmetry in its structure.

Memory Tip

Think of 'straight' ('ortho-') and a 'shape' ('rhombus') to remember that 'orthorhombic' refers to a crystal system with straight, symmetrical angles.
