What else can I help you with?
What type of volcano has a circular base?
uhm i think its shield volcano but im not sure ...... but i kno its between A, HOT SPOT B, CINDER - CONE VOLCANO C, COMPOSITE D, SHIELD VOLCANO or the storage of magma under the volcano
The temperature of magma is between degrees Celsius?
false
What might cause a bulge in the slope of a volcano?
the magma growing in size and large cracks forming
Why do Crystal have different shapes?
They have different developing sites. Restricted, open, magma, and minerals from solution.
How do diamonds get to the surface?
Via rising molten magma or by mining.
Does it take 200 million years for magma to complete one circular convection flow?
Yes it does
Does it take 200 million years for the magma to complete one circular convection flow?
No, the time it takes for magma to complete one circular convection flow can vary depending on factors such as the temperature gradient, viscosity of the magma, and size of the magma chamber. In general, the process of convection in magma chambers can occur on timescales ranging from hundreds to thousands of years.
Does it take about 200 million years for magma to complete one circular convection flow?
No, it does not take 200 million years for magma to complete one circular convection flow. The process of convection in Earth's mantle occurs on a much shorter timescale, typically estimated to be in the range of tens to hundreds of thousands of years. This movement of magma is what drives tectonic plate motion and leads to volcanic activity.
How long does it take the magma to complete the circular convection flow?
The time it takes for magma to complete a circular convection flow can vary depending on factors such as temperature, viscosity, and the size of the magma chamber. In general, this process can take anywhere from days to centuries.
Does it take a million years for magma to complete one circular convection flow?
No, the convection flow of magma within the Earth's mantle is a continuous process that occurs over much shorter timescales, on the order of millions of years, rather than a million years to complete a single circulation. This movement is driven by the transfer of heat from the Earth's core, causing the magma to rise, cool at the surface, and then descend back into the mantle to be reheated.
How can mantle flow because its made of hot liquid magma?
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.
Is cool magma sinking and warm magma convection?
Yes, cool magma tends to sink due to its higher density compared to warmer magma, which rises due to its lower density. This movement leads to convection currents in the magma chambers beneath the Earth's surface.
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 relationship between convection and plate techines?
I'm not familiar with the term 'techines' but I assume it's another word for tectonic plates (i.e. the Earth's crust). In the Earth's core there is a lot of heat produced from the molten iron (magma) of nuclear reactions. As we all know, heat rises. This creates an upward push, forcing the magma to underneath the Earth's crust. The magma then cools as it reaches the top (away from the nuclear reactive core) so then comes down in a circular motion, this circular convection creates a current heading in a certain direction - pushing the tectonic plates in that same direction. This is how plate tectonics are effected by convection currents.
What is the circular motion of heated materials thought to be driving force of plate tectonics?
The circular motion of heated materials in the Earth's mantle is thought to be the driving force behind plate tectonics. This convection current in the mantle causes plates on the Earth's surface to move and interact with each other, leading to processes like seafloor spreading, subduction, and continental drift.
What is the driving force of plate tectonics'?
That force is caused by the convection currents in the magma below the plates.
Describe the mechanism of plate motion?
Plate motion is primarily driven by the process of mantle convection beneath the Earth's lithosphere. Heat from the Earth's core causes material in the mantle to move in a circular pattern, exerting forces on the tectonic plates above. This causes the plates to move, resulting in processes such as subduction, seafloor spreading, and continental drift.
