Trebuchets could fire rocks at a speed of around 160-200 mph, depending on the size and design of the trebuchet. The larger the trebuchet, the higher the potential speed of the projectile.

Which rocks have a name that means ''fire''?

Igneous rocks are rocks that form from the cooling of magma or lava, and "igneous" is derived from the Latin word for "fire." Examples of igneous rocks include basalt, granite, and pumice.


Can lava rocks be used in a wood buring outdoors fire pit?

Yes, lava rocks can be used as a fire pit filler or decorative element in a wood-burning outdoor fire pit. They help distribute heat more evenly and can help with heat retention. Just be sure to verify that the specific type of lava rocks you have are safe for use in high-heat applications.


How do you make afire with rocks?

To start a fire with rocks, you can use the friction method known as fire plow or fire drill. Rub a harder rock against a softer one to create enough friction to generate heat, which can then ignite some tinder. It requires patience, practice, and proper technique to successfully start a fire using rocks.


What happen when rocks rub together?

Depends upon the two rocks and where they are. You will get dust as one stone wears away the other, or they wear away each other depending on the comparative density. Two rocks in a tumbling drum will slowly round each other off, creating smooth roundish stones. If one has iron content, and the other flint, you could create some sparks that could be used to make a fire. If the rocks are coal, you could get a very fine coal dust that can be lit with a match.


What is the meaning of the Latin term ignis from which igneous rocks derive their name?

"Ignis" in Latin means fire. Igneous rocks are named so because they form from the solidification of molten magma, which is essentially cooled-down molten rock from within the Earth's crust or mantle.

How dangerous is the phenomenon of exploding rocks in fire and what precautions should be taken to prevent any potential harm?

The phenomenon of exploding rocks in fire can be very dangerous. When rocks absorb heat and then rapidly cool, they can explode, sending sharp fragments flying. To prevent harm, it is important to keep a safe distance from rocks near a fire, avoid heating rocks directly in a fire, and wear protective gear such as safety glasses when near a fire with rocks.
