It can be estimated if the ages of rocks in layers above and below the volcanic rock are known.
It can be measured reasonably precisely using uranium-lead radioisotope dating as well as techniques based on alpha particle damage to crystals formed in the rock.

What measures the age of volcanic rock.?
Potassium Argon
How can you find the age of a layer of a rock that is surrounded by layers of volcanic ash?
Use PEMDAS
How can you find the age of a layer of rock that surrounded by layers of volcanic ash?
Once you have found a radiometric age for the surrounding layers of volcanic ash, you can safely state that the age of the intervening layer is intermediate between those dates
Volcanic rock a compound or nonmetallic?
Niether. Volcanic rock is a mixture.
What are Frothy volcanic rock are called?
Pumice is a frothy, bubbly, light volcanic rock.
Measures the age of volcanic rock.?
Potassium Argon
What measures the age of volcanic rock.?
Potassium Argon
Whit what unit of measure would scientists use to measure the thickness of the rock layer created as a result of volcanic activity?
Grams
What is the difference between viscosity and volcanic erutions?
Viscosity is a measure of resistance to flow in a fluid. A volcanic eruption is a violent discharge of molten rock and ash.
Is pumice a volcanic rock?
Yes,it is a volcanic rock.
How can you find the age of a layer of rock that is surrounded by layers of volcanic ash?
Use PEMDAS

Can you make fire with volcanic rock?
No. Volcanic rock is not flammable.
Why would you find a volcanic rock on a volcanic island?
Volcanic islands are formed by volcanoes and are therefore composed of volcanic rock.
Scientists use radioactivity in rock samples to measure?
The exact age of the rock.
How can you find the age of a layer of rock that surrounded by layers of volcanic ash?
Once you have found a radiometric age for the surrounding layers of volcanic ash, you can safely state that the age of the intervening layer is intermediate between those dates
Which method for determining the age of artifacts measures the rate of decay in atoms in volcanic rock?
The method used for determining the age of artifacts by measuring the rate of decay in atoms in volcanic rock is radiometric dating, specifically the potassium-argon dating technique. This method relies on the radioactive decay of potassium isotopes into argon isotopes in volcanic rock to determine its age. By measuring the ratio of potassium to argon isotopes, scientists can calculate the age of the rock and any artifacts contained within it.
