The weight of a sample of lava can be very heavy (dense), or it can be porous, such as pumice. The rock itself is heavier than water, but if there are trapped air spaces with the rock, the average density can be less than that of water (it could float).

What type of energy does a lava lamp produce?
Light, heat and kinetic energy.
When rocks from cooling lava harden do they have the same magnetism as Earth's magnetism?
No, because Earth's magnetism "flips" about every half million years. When rock form from the cooling lava of volcanoes, the particular magnetic pattern at the time is "frozen" into the rocks. This was evidence that the alternating pattern of the rock has been slowly spreading out as the new crust is formed.
Is super cooled magma is a state of matter?
Lava is magma that has reached the surface.
How durable and light weight is the chicco travel cot?
The durability and light weight of the chicco travel cot is very good. They are one of the most durable and light weight things that are available in today's stores and companies.
Can we use light to measure the weight of any object?
using the light alone to measure the weight of a unknown object is impossible.
What causes igneous rocks to have holes?
The air and gases escape from the lava as it cools. This makes the little holes that you see. The rock is called pumice.
Are all black rocks lava lava rocks?
no, there are more rocks
Can lava rocks destroy a whole town?

How do you get rid of algae?
Black light, Lava rocks, Running the filter, Getting a algae fish
What is the name given to the molten rock which flows from a volcano?
The rocks inside are called intrusive igneous rocks, however when the volcano explodes it lets out lava which drys into metimorphic rocks.
Is it true that magma that is low in silica usually forms light colored rocks?
Magma doesn't produce lava. Magma is lava. Magma is called magma when it is under the ground but when it is released via a volcano it is called lava when it is above ground. The magma or lava can produce dark to light color rocks after it cools depending on the composition of the magma or lava. There is also a range in the color of the lava depending on it composition and temperature also.
Where are the lava rocks on Petpet Park?
I think the lava rocks are in the volcano on Mt. Puka.
Where are rocks came from?
when lava emerges on out of mountain then the molten lava cool to form rocks.
How extrusive rocks form?
extrusive rocks can form from Basaltic Lava and Andesitic Lava. :)
Why aren't igneous rocks affected by lava?
Igneous rocks aren't affected by lava because they are made of cooled lava.
Does a composite volcano have a mixture of both heavy and light rocks?
A composite volcano is called composite because it has alternating layers of lava and ash, formed by quiet lava flow after explosive eruptions. But yeah, it's definitely made up of both heavy and light rocks !!
What rocks are formed after lava dries out?
Igneous rocks are formed from the cooling and solidification of magma or lava.
