Various gasses escape from magma. Water vapor is the most abundant, but other common gasses include carbon dioxide and sulfur dioxide.
Hot mantle rock rises to fill rift zones. When rock rises, a decrease in pressure causes hot mantle rock to melt and form magma.
Yes, rising magma can become less fluid as it decompresses. When magma rises towards the surface, the pressure decreases, which can cause dissolved gases to come out of the magma and create gas bubbles. These gas bubbles can increase the viscosity of the magma, making it less fluid.
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.
Volcanic eruptions occur when magma rises to the surface and is released as lava, ash, and gases. The build-up of pressure from the molten rock beneath the Earth's crust causes the volcano to erupt. Factors such as the composition of the magma, gas content, and the volcano's geological setting can influence the eruption style and intensity.
The process that explains why less dense hot magma rises to the surface is called buoyancy. When magma is heated, it expands and becomes less dense than the surrounding cooler magma, causing it to rise due to the upward force of buoyancy. As it ascends, it displaces the denser, cooler magma, which sinks. This movement is a key aspect of magma dynamics within the Earth's crust.

A geological hot spot is where hot magma rises from the earth's mantle, which creates volcanic activity.

well, it does. haven't you ever heard of hot lava? that's magma rising from the surface.

Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.

It depends on where the hot spot is located. Felsic magma would be produced if it was under a continent (such as in Yellowstone) whereas Mafic magma would be produced if it was under oceanic crust (such as in Hawaii)
Magma rises to the Earth's surface through volcanic eruptions via conduit or lava channels within the Earth's crust. The buoyant force of the magma, caused by the difference in density between the magma and surrounding rocks, helps drive its upward movement. As the magma rises, it can also accumulate in magma chambers beneath the surface before erupting as lava.

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.
