Where does pumice form?
Vesicular solidified lava, an extrusive igneous rock.
You find a volcanic rock that is fairly smooth and only has a few small holes made when gas and water vapor escaped as the rock cooled you know that the rock can be classified as?
The rock described would be classified as an extrusive mafic igneous rock.
Why does pumice have a lower density than other igneous rocks?
It is a glassy igneous rock, so there are holes in it. The holes make the rock less dense than other igneous rocks that are Not glassy.
Does igneous rocks absorb water?
igneous rocks do absorb water because of all the pores ,cracks, and holes in them. The holes will absorb the water and the water will get trapped in the rock there for igneous rocks do absorb water.
Why does a rock with lots of tiny holes float?
because the air pockets hold enough air to cancel out the weight because water is heavier than air
What can be inferred about volcanic rocks with gas holes in them?
It can be at least inferred that the rocks cooled quickly enough to retain the shape of the gas bubbles, and that they are therefore extrusive igneous rocks.

Pumice is an igneous rock full of tiny holes. Explain how these holes were produced?
how the holes may get there is from the hot lava or magma and since it is very hot it may cause the holes i am not to sure though about my answer.When rocks are heated to melting point, bubbles of gas can get trapped in them. When the rock cools, the gas is left as a hole. Volcanic rock is chock full of holes.

How do animals float?
well they float coz they would have no holes in the body so it could float
What has holes and can float in water?
a cork
What things float then sink?
Boats that get holes in them.
Why do pumice rocks float?
it has holes in it and has kelfrigis
