Geologists classify a volcano made of ash and hardened lava as a stratovolcano, also known as a composite volcano. These volcanoes are characterized by their steep, conical shape and are formed from alternating layers of explosive ash eruptions and lava flows. The combination of these materials contributes to their complex structure and potential for significant eruptions. Examples of stratovolcanoes include Mount St. Helens and Mount Fuji.

What do geologists classify an volcano that is made up of ash and hardened lava?
Geologists classify a volcano made up of ash and hardened lava as a "stratovolcano" or "composite volcano." These types of volcanoes are characterized by their steep profiles and alternating layers of volcanic ash, tephra, and solidified lava flows. They typically produce explosive eruptions due to the viscous nature of their magma, which can trap gas and increase pressure. Examples include Mount St. Helens and Mount Fuji.
What forms as result of lava that has cooled at the top of a volcano?
When lava cools at the top of a volcano, it forms igneous rocks such as basalt or andesite. These rocks can sometimes create formations like lava domes or hardened lava flows.
Is the build up of hardened lava at openings in the Earth's crust from where magma is able to erupt?
volcano
Where is the potential and kinetic energy in a volcano?
Potential energy is found when the lava(magma) is hardened. Kinetic energy is found when the volcano is erupting.
What is wide gently sloping mountain made of hardened layers of low silica lava?
Shield volcano

Does hardened lava form a vent?
No, it forms a volcano.
How do geologists classify a volcano made of these materials?
Geologists classify volcanoes based on the type of material they are made of, such as lava flows, ash, and gases emitted. They also consider the shape and size of the volcano, as well as its eruptive history. These factors help categorize volcanoes into different types, such as shield volcanoes, stratovolcanoes, and cinder cone volcanoes.

Is a wide gently sloping mountain made of hardened layers of low silica lava a cinder cone volcano?
Shield volcano
Where is the potential and kinetic energy in a volcano?
Potential energy is found when the lava(magma) is hardened. Kinetic energy is found when the volcano is erupting.
Where do lava tube caves form?
Lava tube caves form when low viscosity lava flows beneath the hardened surface of lava flow while the volcano is active. Then when the volcano is dormant or extinct, it leaves cave like channels.
Why don't erupted hardened lava cover up the holes of volcanoes?
Because the lava flows down the sides of the volcano before it hardens.
What is wide gently sloping mountain made of hardened layers of low silica lava?
Shield volcano
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.
What are the physical features of a compostie volcano?
Tall cone shaped mountains that have alternate layers of hardened lava and ash.
