What else can I help you with?
What type of volcano is build almost entirely from ejected lava fragments?
The type of volcano that is built entirely of ejected lava fragments is a volcanic cone. Volcanic cones can be of varying types, and it depends upon the nature, and size of the fragments ejected during the eruption.
What is the definition of lava bomb?
A lava bomb is a large rock fragment that is ejected from a volcanic vent during an eruption. These fragments are molten when airborne and can solidify into igneous rock as they cool and fall back to the ground. Lava bombs can range in size from small pebbles to massive boulders.
What Magma and lava can both solidify to produce?
They are both the same thing, which is melted rock, which means they solidify to form rock. The only difference between magma and lava is that magma is underground, and lava is not.
Is scoria volcanic glass?
Yes.Scoria ("lava rock") is found on the surface of lava flows or in fragments that have ejected from the volcano's explosive opening. In these conditions, the molten rock was immediately exposed to the open air on the Earth's surface, causing it to cool and solidify very rapidly. This solidification process is too quick for atoms within the solution to bind together to form large crystals, so the solid rock is consequently made up of tiny glassy fragments that are amorphous, or do not contain crystalline structures. Since scoria is made up of these glass fragments, it is defined as VOLCANIC GLASS.
What are the pieces of moten rock called that are thrown out of a volcano?
The Rock That Comes Out Of A Volcano Is A Igneous Rock.
Does nothing beat lava?
Cold (almost freezing) water applied to lava can slow the flow and eventually cause it to solidify.
What type of volcano is build almost entirely from ejected lava fragments?
The type of volcano that is built entirely of ejected lava fragments is a volcanic cone. Volcanic cones can be of varying types, and it depends upon the nature, and size of the fragments ejected during the eruption.
What does cooling magma solidify into?
Lava
What type of volcano is built almost entirely from ejected lava fragments?
A cinder cone volcano is built almost entirely from ejected lava fragments. These fragments can range in size from ash to bombs and are ejected during explosive eruptions. Over time, these layers of eruptive material accumulate to form a steep-sided cone-shaped volcano.
What is the definition of lava bomb?
A lava bomb is a large rock fragment that is ejected from a volcanic vent during an eruption. These fragments are molten when airborne and can solidify into igneous rock as they cool and fall back to the ground. Lava bombs can range in size from small pebbles to massive boulders.
Can lava be a crystal?
Lava itself is not crystalline as it is liquid. Crystals are solid. However, lava can contain crystals of minerals that have started to solidify.
What Magma and lava can both solidify to produce?
They are both the same thing, which is melted rock, which means they solidify to form rock. The only difference between magma and lava is that magma is underground, and lava is not.
WHERE DOES LAVA COOLS QUICKLY?
Lava cools quickly when it comes into contact with water, such as in the ocean or a river, where it can solidify rapidly due to the contrast in temperature. Additionally, lava can cool quickly when it flows over ice or snow-covered terrain, causing it to solidify and form unique lava formations.

What is the difference between cinder cones and spatter cones?
A spatter cone is formed of molten lava ejected from a vent of a volcano. Expanding gases in the lava fountains tear the liquid rock into irregular gobs that fall back to earth, forming a heap around the vent. The partly liquid rock splashes down and over the sides of the developing mound is called spatter. Because spatter is not fully solid when it lands, the individual deposits are irregular in shape and weld together as they cool, and in this way differ from cinder and ash. A cinder cone is a volcanic cone built almost entirely of loose volcanic fragments called cinders. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most cinder cones have a bowl-shaped crater at the summit.
What are the pieces of moten rock called that are thrown out of a volcano?
The Rock That Comes Out Of A Volcano Is A Igneous Rock.
What happens to lava when its been lying on the ground for a while?
The lava which at first is liquid rock, will solidify into extrusive igneous rock.
