What color is pumice when smashed?
Pumice, being a rock composed of possibly a number of various minerals, does not have a streak color as such. Powdered pumice would reflect a combination of the streaks of the constituent minerals.
When you rub a pumice rock on a streak plate what color is left on the streak plate?
The streak left on the streak plate by rubbing a pumice rock usually appears white or colorless. This is because pumice is a light-colored rock composed of volcanic glass with a frothy texture due to gas bubbles trapped in the rock, causing it to create a light streak when rubbed on a streak plate.
Does black rocks float?
No rocks float, irrespective of color with the exception of pumice, a solidified lava froth.

What type of rock is porous volcanic rock?
Porous volcanic rock is commonly classified as either pumice or scoria. Pumice is often lighter in color and has a very porous texture due to the presence of numerous gas bubbles, while scoria is darker and similarly porous but is typically more dense than pumice. Both are formed from volcanic eruptions and can float on water.

Why is pumice white not black?
Pumice can vary in color from white to gray to black. Much of it has to do with the chemical composition. Felsic varieties are most commonly light in color. Mafic varieties can be darker in color.
What is the streak of pumice?
Pumice forms when frothy lava cools rapidly, trapping gas bubbles within the rock. This gives pumice its characteristic streaks or veins, which are typically lighter or darker in color than the rest of the rock. The streaks in pumice can vary depending on the mineral and chemical composition of the magma from which it formed.
