what is mountain formed from layers of lava and ash
A mountain formed from layers of lava and volcanic ash is referred to as a composite volcano. Composite volcanoes form over continental hot spots and continental volcanic arcs. Their composition is felsic, meaning that they have high silica content and low iron and magnesium content. Since felsic lava is extremely viscous (thick, as opposed to watery), composite volcanoes are often tall and have steep sides. Mount Fuji in Japan is a composite volcano. When a composite volcano erupts (often explosively), lava flows out of the top and cools on the slope. Pyroclastic debris later settles on the slope. This process is repeated each time the composite volcano erupts, resulting in layers of lava and volcanic ash.
A mountain that is formed by lava ash is a volcano.
Pyrolastic Flow- a super hot avalanche of rock and ash.
Eruption Cloud- ash and toxic gases that pollute the atmosphere.

A glacier forms as layers of snow build up. The weight from the upper layers of snow pack down the lower layers until the lower layers become very hard and form ice.

A dome mountain forms when magma is injected into the Earth's crust and starts to push upward, creating a bulge or dome shape. As the magma cools and solidifies beneath the surface, it forms a layer of hardened rock. Over time, erosion gradually removes the overlying layers, exposing the dome-shaped mountain.
