Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
What else can I help you with?
What provides the force that causes magma to erupt to the surface?
The force that causes magma to erupt to the surface is primarily due to the build-up of pressure from the expansion of gases within the magma chamber. As the pressure exceeds the strength of the surrounding rock, the magma forces its way through the crust to reach the surface, resulting in an eruption.
What provide the force that causes magma to erupt to the surface?
Convection, and thermal expansion.
What provides the primary explosive force that results in a eruption?
The primary explosive force that results in an eruption is the release of built-up pressure in the Earth's mantle. This pressure is caused by the accumulation of magma beneath the surface, which contains volatile gases such as water vapor and carbon dioxide. When the pressure becomes too great, it causes the magma to explosively erupt to the surface, resulting in a volcanic eruption.
Can density difference force magma upward into cooler layers of earths interior?
FALSE: gravity cannot force magma upwards, gravity can olny force downwars. the reason magma shoots from the earths interior is because the pressure from the magma trying to push through the force gravity causes an eruption.
The force that cuases magma to erupt at the surface is provided by?
heat
What force pushes out magma out of a volcano onto the surface?
Pressure.
What provides the force that propels magma from a volcanic vent?
Lava moves from its viscosity.
Causes of volcanicity?
Magma in mantal is under great heat and high temperature. Once there is a crack or we called a line of weakness appears on crust's surface,magma would escae to the surface from mantal.Volcanic ashes,gases and magma would throw out and causes volcanic eruptions.
What causes the magma inside a volcano to rise to award the surface?
The molten magma increases in pressure (like a pressure cooker at home) until it is forced towards the surface.
What process causes liquid rock to move?
Vulcanism is the process that forces liquid rock (magma) from deep within the Earth, up to the surface. Once the rock is expelled from a Volcano, the force of Gravity makes it flow down the sloped surface.
What is the force that move the Earth's plates?
The force that causes most of the plate movement is thermal convection, where heat from the earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the of plate the crust along with them.
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.
