As lava cools, it hardens and forms a thick layer of rock. These rocks are known as igneous rocks. An example of an igneous rock is pumice, which is used in spa treatments to soften feet.

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.
Why does a volcano shape like a mountain?
When the volcano erupts, lava comes out and hardens on the surface of the volcano. If the volcano keeps erupting, then the hardened lava will create layers which cause the volcano to get taller like a mountain.
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.
Is the build up of hardened lava at openings in the Earth's crust from where magma is able to erupt?
volcano
What type of volcano is a buildup of basaltic layer's forming a broad volcano with gently sloping sides?
A shield volcano

Does hardened lava form a vent?
No, it forms a volcano.
What is a hardened layer of magma called?
laccolith
What is the outer layer of a volcano called?
There is no specific term for the outer layer of a volcano.
What landforms forms from hardened magma in the pipe of an extinct volcano?

What created the hawaiian island?
There was a small volcano and when it erupted, it hardened and created islands.
Hardened magma squeezed into vertical spaces are what type of volcano?
igneous dike
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.

After millions of years what landforms form from hardened magma in the pipe of an extinct volcano?
Volcanic neck
