when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
What else can I help you with?
Does cooler magama flow more or less quickly than hotter magma?
Cooler magma flows slower than hotter magma.
Does cooler magma flows more or less quickly than hotter magma?

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.
Which process explains why less dense hot magma rises to the surface to displace more sense and cooler magma?
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.
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.
How is convection current related to earth's mantle?
It allows for the cycling of magma that is cooler than the rest to sink further down under where it's warmer and the warmer magma to rise up further because it is less dense and get cooler where the cooler magma used to be.
Do plates become more dense or less dense when they become cooler?
Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.
Can thermal energy be cool when its hot?
Yes. But a cooler body has less energy than a hotter object
What happens when the mantle gets hotter?
When the mantle gets hotter, it becomes more fluid and less viscous, causing it to flow more easily. This increased flow can lead to the movement of tectonic plates and the creation of volcanic activity as magma rises to the surface. Additionally, higher temperatures in the mantle can affect the density of the material and impact convection currents within the Earth's interior.
Are Basaltic lavas generally hotter and more viscous than andesite lavas?
Basaltic lavas are generally hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which makes them flow more easily. Andesite lavas, on the other hand, have higher silica content, making them cooler and more viscous.
Why magma floats to the surface?
Magma floats to the surface because it is less dense than the surrounding rock. As magma rises, its buoyancy overcomes the pressure of the rock above it, allowing it to flow upward towards the surface. The expansion of gases within the magma also helps to propel it upward.
Is red stars cold?
No. Red stars emit less energy so they are cooler than hotter blue stars.
