What are ash falls?
An ash fall is a rain of airborne ash resulting from a volcanic eruption.
What are the precautionary measures after volcanic eruption?
People in a volcano zone need to be removed until the ash and lava have finished coming out of the volcano. Homes and businesses need to be evacuated and cars are moved out of the way. The volcano will need to be done erupting before people are allowed back into the area.
Why is volcanic ash such a good time marker?
because it has lots of minerals from the rock in it.
What Stages that lead up to volcanic eruption?
Fire,Ash,smoke clouds, and earthquakes
What is the state of volcanoes currently spewing smoke ash steam cinders and lava?
active
Does volcanic ash create basalt?
No. While volcanic ash can have a basaltic composition, it usually does not. Basalt forms from lava. Volcanic ash forms tuff.
What is volcanic material thrown out during erputions?
volcanic ash, volcano bombs, and lava
What us the surface of volcanic mountains made of?
Solidified lava, sulphur, volcanic ash.
What is the definition of layer of ash and lava?
A layer of ash and lava is a geologic feature formed by the deposition of volcanic ash and solidified lava during volcanic eruptions. These layers can build up over time to create thick sequences of volcanic material, which can be preserved in the rock record as distinct stratigraphic units.
Lava flows and volcanic ash are examples of magma that has reached the earth's surface true or false?
True. Lava flows and volcanic ash are indeed examples of magma that has reached the earth's surface during a volcanic eruption.
Differences between lava and ash landforms and magma landforms?
Lava landforms are created by the eruption and cooling of molten lava on the Earth's surface, forming features like lava flows, lava domes, and lava tubes. Ash landforms are the result of volcanic eruptions that produce ash and volcanic debris, creating features like cinder cones, ash clouds, and pyroclastic flows. Magma landforms are underground structures formed by the cooling and solidification of magma, such as plutons, batholiths, and dikes.
What are rocks produced from lava and ash in volcanoes called?
volcanic rock
What build up a volcanic mountain?
Cinder, cooled lava, and ash
What are formed when the lava and ash escapes at the surface?
Volcanic landforms and features.
What is a sentence using the word volcanic?
The volcanic eruption spewed ash and lava into the sky, causing widespread destruction and chaos.
What is the difference between acid lava cones and ash and cinder cones?
Acid lava cones are smaller and much steeper than ash/cinder cones. Acid lava cones are almost convex in shape and are formed due to thick lava that does not flow freely and cools before reaching very far. This gives in the conical 'dumpy' shape. While ash and cinder cones are more symmetrical and concave in shape. They are formed due to volcanic lava or volcanic bombs (of solidified lava) that was shot up in the air, cool and hardened and broke up into tiny pieces (of ash or cinders) before coming back down to the earth's surface.
Why is volcanic ash magnetic?
Volcanic ash contains magnetite, which is a naturally occurring magnetic mineral. During the cooling of lava, magnetite crystals form within the ash particles, giving them magnetic properties. This magnetic nature of volcanic ash can be useful in various scientific studies and dating techniques.
