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.
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.
Potential energy is found when the lava(magma) is hardened. Kinetic energy is found when the volcano is erupting.
volcano
A cinder cone erupts quickly and makes a hill made of small pieces of hardened lava.
A shield volcano
The hardened layer of lava is called "igneous rock".
A hardened layer of magma is called a lava flow or volcanic rock.
No, it forms a volcano.
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.

There is no specific term for the outer layer of a volcano.

The volcano that made the Laetoli footprints possible is the nearby Sadiman volcano, which erupted about 3.6 million years ago and covered the site with a layer of ash. This ash then hardened, preserving the footprints made by early hominins as they walked across the area.
igneous dike
There was a small volcano and when it erupted, it hardened and created islands.
Shield volcano
