Here's why your question is a bit tricky:
* Granite is a material, not a defined object: You can't ask the height of "wood" or "steel" because it's a material that can take many forms.
* Granite formations vary greatly: Some granite formations are just a few feet tall, while others, like Half Dome in Yosemite, are over 8,800 feet tall.
So, instead of asking about the height of granite, you might ask:
* What is the height of a specific granite formation? (For example, "What is the height of El Capitan?")
* What is the typical height of granite cliffs? (This is a more general question, and the answer will depend on the specific location.)
Let me know if you have a specific granite formation in mind!
