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).
Approximately 2,700 pounds on average.
Shale is considered a medium-weight rock. It typically has a density between 2.6 to 2.8 grams per cubic centimeter, which places it in the medium weight category among rocks.
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.
When heat is taken away from hot lava, it begins to cool and solidify into solid rock. This process can result in the formation of volcanic rocks such as basalt or obsidian, depending on the speed at which the lava cools.
A lava lamp does not produce energy; it uses a combination of heat from the lamp bulb to warm the wax and density differences to create the mesmerizing lava lamp effect.
no, there are more rocks
Approximately 2,700 pounds on average.
Lava is a liquid, not 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.
when lava emerges on out of mountain then the molten lava cool to form rocks.
I think the lava rocks are in the volcano on Mt. Puka.
extrusive rocks can form from Basaltic Lava and Andesitic Lava. :)
Igneous rocks aren't affected by lava because they are made of cooled lava.
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 !!
The molten rock that flows from a volcano is called lava.
Igneous rocks are formed from the cooling and solidification of magma or lava.
