When Magma Is Forced Upward at Rory Evans blog

When Magma Is Forced Upward. The rifting movement causes the buoyant magma below to rise and fill the space. Magmatic processes occurring within the earth's crust The molten rock, less dense than its solid surroundings, starts to rise toward the surface. Magma from partial melting of mantle rocks rises upward through the mantle, and may pool at the base of the crust, or rise through the crust. Moving magma carries heat with it, and some. Decompression melting often occurs at divergent boundaries, where tectonic plates separate. Magma compositions vary, but will have eight main elements in different proportions. Once magma makes it to the surface, it’s called lava. The most abundant elements are oxygen and silicon, followed by aluminum, iron, calcium, sodium, magnesium, and potassium. Igneous rocks form when melted rock cools, and melted rock originates within earth as magma. The end of that journey is eruption, sending the magma out through openings in the crust along with volcanic gases and, depending on the type of eruption, billows of ash.
