What is dust sized particles of hardened lava?
Dust-sized particles of hardened lava are known as volcanic ash. They are created during volcanic eruptions when molten lava is explosively ejected into the air, cools rapidly, and shatters into tiny fragments before falling to the ground. Volcanic ash can travel long distances and have significant impacts on human health, agriculture, and the environment.
Does the lava harden?
Actually, it does not. It is soft.
Does steam gas and dust pile up harden and form a volcano?
Steam and gas cannot pile up. Stratovolcanoes are composed of piles of volcanic ash ("dust") and lava flows. Cinder cones are composed of piles of rock fragments. Shield volcanoes are composed of layers of lava flows.
What are the names of rocks that harden before they come out of the volcano and the name of rocks that harden after they come out of a volcano?
It is called Lava
What happens to magma and lava when they coll and harden?
it turs to rock
How do volcanoes shape the Pacific Northwest?
volcanoes will erupt and let out lava then the lava will harden and that will be new land.
Compared to the particles in a hardened lava sample the particles in a liquid lava sample?
The particles in a hardened lava sample will be solidified and compacted, while the particles in a liquid lava sample will be molten and in a flowing state. The hardened lava particles will have a crystalline structure, whereas the liquid lava particles will lack a fixed arrangement due to their high temperature.
Why does lava harden?
Because it cools down and changes its state of mater.
How was a diamond formed?
lava helps harden with stone and minerals grow it
What happens after lava harden and turnes into igneous?
It hardens and turns it to rock.
What rock is formed when magma and lava cool and harden?
Igneous Rock.
Is during an volcanic eruption particles called lava ranging from very fine dust to pieces weighing several tons are ejected?
They are called fragments, fragments.
