The study of rocks is called Petrology, and the scientists that study them are called petrologists. Petrology is a sub branch of geology.
Volcanoes are studied by volcanologists.
geologist study geography such as waterfalls (dont know the specific type of scientist)
Geology
extrusive igneous rock (study island)
A vulcanologist
A vulcanologist is most likely to study the cooling of lava after a volcanic eruption
geologist
lava volcano#
Volcanologists, or scientists who study volcanoes, are most likely to study the cooling of lava. They are interested in understanding the behavior, properties, and processes associated with volcanic eruptions, including the cooling and solidification of lava after it is erupted from a volcano. By studying the cooling of lava, volcanologists can gain insights into various volcanic phenomena and hazards.
When they study the lava they study what is inside the lava like how much silica, magnesium, iron etc then they can tell what kind of eruption it was.
pure scientists
Vulcanologists are scientists that study volcanos and anything relating to volcanos (including magma, lava, etc...).
Ornithologists
A microbiologist.
The study of rocks is called Petrology, and the scientists that study them are called petrologists. Petrology is a sub branch of geology.
Vulcanologists and, at a later stage, geologists.
