How can you find the age of a layer of a rock that is surrounded by layers of volcanic ash?
Use PEMDAS
Layers of lava emitted by the volcano?
The different layers of a volcano are made from the lava and ash produced by the volcano. Some volcanoes have different thicknesses of layers or only one type of layer depending on the kind of eruption and how much ash it produces.
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
What kind mountain is mount st Helens?
Mount St. Helens consists of lava rock interlayered with ash, pumice and deposits, together with layers of basalt and andesite.
What are the Layers of volcanic eruption?
In a cinder cone volcano, layers of ejected lava are combined with "pyroclastic" layers, formed of "tephra" : hot gas and rock that flow from the cone. The classic volcanic cones are composed of several parts : * Cone - the mound of ash and cinder * Crater * - the main opening, usually at the peak or summit * Vents - openings from the cone * Conduits - the lava channels connected to the vents * Magma chamber - the underground source of the liquid rock for the volcano *A "caldera" is a collapsed area, usually formed when a magma chamber empties. This is distinct from the term crater.
What type of the volcano has alternate layers of ash and lava?
Composite

What type of volcano is composed of ash and rock?
A a stratovolcano.

What type of rock is tuff?
volcanic - it is made form volcanic ash that has solidified.

Mount St. Helens consists of lava rock interlayered with ash, pumice and deposits, together with layers of basalt and andesite.
Would it be likely to find fossils of the older reptile species in rock layers younger than the volcanic ash?
not really, i don't think so.
What are Ash Eruption?
Ash eruptions are when a volcano emits lots of ash and rock instead of lave and throughs them really high into the air and depending on the type of volcano really far as well.
Why don't sedimentary rocks form from particles deposited by fire?
The volume of ash produced by a fire is not large enough to produce significant amounts of rock. We do find evidence of fires in rock layers, though.
