The sharpest rocks on Earth are typically volcanic glass, such as obsidian, which can fracture with razor-like edges. These edges can be incredibly sharp and are often used for cutting tools in ancient and modern contexts. Other sharp rocks include certain types of quartz, particularly when they are finely fractured, allowing for sharp points and edges. Overall, volcanic glass is renowned for its exceptional sharpness.

Geologists can't use rocks from Earth to determine the planet's age because those rocks have all been recycled through the rock cycle over time. This means that the original rocks from when Earth formed no longer exist. Instead, geologists use radiometric dating of rocks from Earth's surface to estimate its age.
