Similar experiential requirements are imposed in other countries as well. To become a neuroradiologist, a medical degree is required. 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.

Confidence votes 703. pahoehoe,lava with a smooth ropy surface. This type of lava is generated by Basaltic magma, which is very fluid in nature and drives very fluid lava flows once on the surface. This type of magma allows gas to flow readily out of it making explosive eruptions a rather rare phenominon.ahoehoe,lava with a smooth ropy surface.
