What else can I help you with?
Could property of magma that cause it to be forced upward towards earth surface?
Because magma is less dense than the surrounding solid rock, it is forced upward toward the surface. When magma reaches the surface and flows from volcanoes, it is called lava.
Is magma more dense then rock?
No. Magma varies in density, but it will be less dense than a solid rock of the same composition.
Is liquid magma less dense or more dense?
Liquid magma is less dense than solid rock because it is a molten mixture of rock, minerals, and gases. When magma rises to the Earth's surface and cools, it solidifies into igneous rock.
What is the magma type for a lava dome?
The magma type for a lava dome is typically viscous and silica-rich. This type of magma often leads to slower, more explosive eruptions that result in the gradual buildup of a dome-shaped feature composed of solidified lava.
Lava and magma?
Lava is molten rock that erupts onto the Earth's surface, while magma is molten rock beneath the surface. The temperature and pressure difference between them affect their behavior and appearance. Lava typically flows more fluidly, while magma can be trapped underground in magma chambers.
When lava breaks through the earth's crust?
that is a volcano starting 100 years would pass and then it becomes more of a volcano.
Why is magma stiffer than lava?
Magma is typically stiffer than lava because it contains more gas bubbles and crystal structures that can restrict flow. When magma rises to the surface and cools, the gas bubbles escape and the crystal structures align, allowing lava to flow more easily.
Lava is more commonly known by what word that starts with the letter m?
magma!
Which process explains why less dense hot magma rises to the surface to displace more densecooler magma?
The process that explains why less dense hot magma rises to the surface is called buoyancy. When magma is heated, it becomes less dense than the surrounding cooler magma, allowing it to rise through the crust. As it ascends, the hot magma displaces the cooler, denser magma, which is more likely to sink. This movement is driven by the differences in density and temperature, contributing to volcanic activity.
What igneous rock is formed from magma or lava cools and hardens?
Cooled magma, lava, or pyroclastic material is igneous rock. Cooled magma forms intrusive igneous rock, while lava and pyroclastic material form extrusive rock. Anything beyond that depends on more specific factors.
Which process explains why less dense hot magma rises to the surface to displace more dense cooler magma?
This process is known as mantle convection. The hotter, less dense magma rises while the cooler, denser magma sinks, creating a circular motion within the mantle. This movement of magma is driven by differences in temperature and density, ultimately leading to the displacement of magma at the surface.
What is the cause of tectonic plates?
One suggestion for the cause of plate tectonics is mantle convection which is the result of cooling and heating magma. You could think of mantle convection much in the same way lava flows in a lava lamp. Lava rises in a lava lamp because it heats up and becomes less dense. While at the top of the lava lamp, the heated lava begins to cool (because it's further away from the heat source (e.g. light) at the bottom) becoming more dense and then sinks back down to the original heat source where it will be reheated. This mantle convection is thought to work somewhat like a large conveyor belt in which the plates sit, moving them along.
