What can't lava burn?
One material lava can't melt is stainless steel.
Why doesn't lava melt the rock around it if it lava usually melts rock?
It takes quite a lot of heat to melt rock, and whatever is melting that rock must loose heat in the process. When molten rock comes out of a volcano, it is closer, in terms of temperature to solidifying than the surrounding rock is to melting. So the lava will cool and harden before the surrounding rock has a chance to melt, especially since the lava is also losing heat to the air. In some cases the surface rock may melt, but in fairly small amounts.
Give one reason that a very hot rock might not melt?
When fluids are added to rocks that are already very hot, the rocks can melt. But, the rock might not melt if it doesn't have any fluid in it.
Will steel melt when touched by lava?
No. Lava is generally not hot enough to melt steel.
How come lava doesn't burn Igneous rocks?
Ignoues rock is not flammable, therefore it does not burn. In order to melt the igneous rock, the lava must transfer an enormous amount of heat to it. However, lava will quickly lose heat to its surroundings and will generally cool before it can do this.
What type of rock does lava turn into if it doesnt melt?
Lava IS molten rock therefore your question is meaningless.

Can rocks melt during the rock cycle?
Absolutely. If a rock is heated up by subduction into deeper parts of the earth, or even if it is in contact with other molten rocks (like lava) it can melt.
What could make a rock melt?
The sun Any extreme heat. Lava, fire, kiln, blowtorch (if the rock is soft enough.)
Can a volcano be red?
yes. lava is red. and if lava heats up the rock alot without melting, the rock will turn bright red but will not be visible from the outside because the extreme heat will melt the rock slowly from the inside
Is lava rock safe for fish?
no, lava is molten rock, it's extremly hot, and can melt even the hardest metals straight away, it would turn fish into a friday night feast.
