Magma
Volcanoes melt the rock and eventually erupt. Once it erupted the rock starts to setal and cool into a certain type of rock
is a volcanic eruption part of the rock cycle
is a volcanic eruption part of the rock cycle
Heat, pressure, weather, gravity, plate tectonics--all play a part in the rock cycle.
Yes. Most volcanoes on Earth are associated with plate boundaries.
sedimentary rock
Both water droplets and droplets from volcanoes are part of the water cycle. Water droplets form from condensation when water vapor in the air cools and changes phase. Droplets from volcanoes are created from the ejected molten rock, ash, and gases that cool and solidify in the atmosphere.
A river can cause a cliff when moving the soil and rocks out to somewhere else. Volcanoes can make the Earth's crust wider.
They all are part of the rock cycle
compaction and cementation are the only parts of the rock cycle that cannot be observed.
it depends what part of the world you come from. because pumice is a type of rock produced by volcanoes if you lived in a part of the world where ther are lots of volcanoes then no it would not be a rare substance but if you lived in a part of the world that ther was no volcanoes then pumice would be rare .Pumice is not rare it is a very common volcanic rock.
Heat from the earth's core, via the magma drives the tectonic part of the rock cycle. This heat is derived mainly from radioactive fission of the heavy elements in the Core.Gravity drives much of the weathering part of the rock cycle. Via evaporation of water, and rain and rivers, and glaciation.Some solar radiation also energizes part of the weathering part of the rock cycle.
