The molten inner mantle of the earth is under extremely high pressure, and is also extremely hot. Therefore, the reason volcanoes are created (and erupt) is because sometimes, the magma begins to go upwards (it can't go anywhere else) because of the immense pressure.
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
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.
This phenomenon is known as a subduction zone. It occurs when one tectonic plate is forced beneath another, leading to the melting of the descending plate and the formation of magma. This magma can then rise to the surface as volcanic activity.
The process that causes water on Earth's surface to change to gas and rise into the atmosphere is called evaporation. This occurs when the sun's heat energy causes water molecules to gain enough energy to break free from the liquid's surface and enter the air as water vapor.
A mid-ocean ridge is where magma pushes up on oceanic lithosphere, creating new oceanic crust as the magma solidifies. The heat from the magma causes the lithosphere to rise and spread apart, resulting in seafloor spreading. This process is fundamental in plate tectonics theory.
The tectonic plates push together thus causing magma to shoot up and rise hence an eruption
During a volcanic eruption or on a constructive boundary
The magma is in the mantle, the layer under the crust. There is a convection current caused by radioactivity in the inner core which causes the plates to move. Therefore the constructive plates move apart which means magma can rise up. It'll then solidify and this is what makes volcanoes. Hence CONSTRUCTive.
Through cracks, holes or vents in the earths crust.
The molten magma increases in pressure (like a pressure cooker at home) until it is forced towards the surface.
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
Magma flows out of a weak spot in the Earth's crust due to the build-up of pressure from the molten rock beneath the surface. This pressure can result from the heat and movement of tectonic plates, creating pathways for magma to rise and eventually erupt onto the surface as lava.
Increasing pressure pushes the magma upwards. This rising pressure can be caused by many different things.
It is less dense than its surrounding rock matter
What property of magam cause it to rise towaed earths surface?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
Magma is less dense than the surrounding rock; as such, it will rise toward the surface.
