when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
Cooler magma flows slower than hotter 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.
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.
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.
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.
Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.
Yes. But a cooler body has less energy than a hotter object
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.
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.
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.
No. Red stars emit less energy so they are cooler than hotter blue stars.
