How do composite volcanoes form?
Composite volcanoes form from alternating layers of lava flows, ash, and volcanic rocks that build up over time. This type of volcano is created by a combination of explosive eruptions and lava flows, which allow for the formation of the steep symmetrical shape commonly associated with composite volcanoes.
What is layer of lava and ash?
When molten rock (lava) flows from a volcano, it covers the surrounding area in a layer of solidified rock. During the eruption, ash can also be thrown up high into the sky by the volcano, and blown by the wind, could settle in a thick, smothering layer. The city of Pompeii suffered from being smothered by volcanic ash.
Why is another name for composite volcano Strato?
A composite volcano is called a "strato" volcano because of its alternating layers of lava flow and volcanic ash, which can resemble the stratified layers of sedimentary rock ("strato" means layers in Latin). This type of volcano is characterized by its steep-sided profile and explosive eruptions.
Where does the ash of a volcano come from?
Volcanic ash forms when magma is explosively ejected from a volcano. The explosive force of expanding gasses in the magma blasts it apart into small particles, which then solidify to form tiny shards of glass.
What is an ash deposit layer?
An ash deposit layer is a layer of ash that accumulates on the ground after a volcanic eruption. It is composed of fine particles of volcanic ash that settle out of the ash cloud during or after the eruption. Ash deposit layers can vary in thickness and composition depending on the size and intensity of the eruption.
How do composite volcanoes form?

This type of volcano is created by a combination of explosive eruptions and lava flows, which allow for the formation of the steep symmetrical shape commonly associated with composite volcanoes.
A volcano formed over time from thousands of lava eruptions that deposit layer after layer of new crust?
Yes, volcanoes are formed by the accumulation of lava and volcanic materials over time from repeated eruptions. As the lava cools and solidifies, it builds up to create the structure of the volcano. This continuous process can lead to the formation of a cone-shaped volcano with layers of hardened lava.

How is ozone layer formed?
See "How was the ozone layer formed?"
What is the formed of ozone layer?
Ozone layer is formed of ozone. It is a gas.
How it is the ozon layer formed?
The ozone layer is formed by UV rays. It is also formed by thunder.
In the upper layer of the atmosphare ozone is formed by?
The upper layer of the atmosphere is formed by ozone layer. This is a layer of ozone gas.
Where is the ozone layer formed and stored?
Ozone layer is formed all over the earth. It is there in stratospheric layer.

What kind of pyroclastic marterial can reach the upper atmosphere and circle the earth for years?
Volcanic ash, sulfur dioxide, and other particles ejected during explosive volcanic eruptions can reach the upper atmosphere and form a stratospheric aerosol layer. This layer can reflect sunlight, causing cooling effects on Earth's surface and result in the phenomenon known as volcanic winter. Examples of such events include the 1991 eruption of Mount Pinatubo and the 1815 eruption of Mount Tambora.
What is the source of ozone layer?
