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
Why do Crystal have different shapes?
They have different developing sites. Restricted, open, magma, and minerals from solution.
What might cause a bulge in the slope of a volcano?
the magma growing in size and large cracks forming
How do diamonds get to the surface?
Via rising molten magma or by mining.
Does it take a million years for magma to complete one circular convection flow?
no it doesnt
Does it take 200 million years for magma to complete one circular convection flow?
Yes it does
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.
Does it take 200 million years for the magma to complete one circular convection flow?
yes it do, basically its simple to know that common sense
How long does it take the magma to complete the circular convection flow?
About 50 minutes.
What is the circular motion of heated materials thought to be driving force of plate tectonics?
Convection / Magma
Is cool magma sinking and warm magma convection?
When cool magma sinks and warm magma rises, yes that is convection.
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.
What is happening to create convection currents in the mantle?
in the asthenosphere, which is in the lower part of the mantle, magma churns in a convection current which is like a cycle. Tectonic plates sit above this movement in the lithosphere. This is what causes continents to move little by little. Hot magma rises and at the lithosphere, it cools and falls because it is now denser. This is like a circular movement, or convection current.
What is tectonic convection?
Your probably referring to the magma convection currents within the mantle. Like normal heaing and cooling convection currents, the magma ebbs & flows, keeping the tectonic plates in motion.
What is the magma cycle called?
a convection current
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.
