In the United States, this is obtained by successfully completing four years of undergraduate studies and four years of medical school.hile the requirements to become a neuroradiologist vary among and even sometimes within countries, a career in neuroradiology typically requires many years of study, including a bachelor's degree and a medical degree.
When magma reaches the surface of the earth, it is called lava. Since it its a liquid, it flows downhill in response to gravity as a lava flows. Different magma types behave differently as lava flows, depending on their temperature, viscosity, and gas content.hen magma reaches the surface of the earth, it is called lava.

Report Abuse. A volcano is a mountain where lava (hot, liquid rock) comes from a magma chamber under the ground. Most volcanoes have a volcanic crater at the top. When a volcano is active, materials come out of it. The materials include lava, steam, gaseous sulfur compounds, ash and broken rock pieces.team (water) molten rock Lava and rock fragments this all causes a pyroclastic flow to the person that says pyroclastic flow, pyroclastic flow isn't a material emmitted from the volcano. a pyroclastic flow is what happens using the materials which come out of the volcano.
