What else can I help you with?
When convection takes place in the matle why does cooler material sink while warmer material rises?
Cooler material (magma) shrinks and becomes more dense. Gravity acts on this denser material more strongly because of its greater unit mass (density = Mass/volume). Lighter material rises as the heavier material displaces it below. This produces a the apparent bouyant force.
What is the molten material under the earth's crust?
Magma
What is the melted material beneath the Earth's surface?
This material is most often referred to as magma.
Magma is molten material that forms .?
Magma is molten material that when cooled forms a solid called igneous rock
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.
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.
What is the melted mineral material in the mantle called?
The melted mineral material in the mantle is called magma.
Where do you get your magma from?
Magma comes from the melting of material in the crust or upper mantle.
What is a convectional curent?
A convection current is a type of movement in fluids (liquids or gases) that is driven by differences in temperature or density. Warmer, less dense material rises while cooler, denser material sinks, creating a circular motion of flow. This process helps transfer heat energy within fluids, such as magma in the Earth's mantle or air in the atmosphere.
Melted material that rises from the mantle is called?
Melted material that rises from the mantle is called magma. Once magma reaches the Earth's surface, it is then referred to as lava.

What are convection current and how are they formed?
Convection currents in the earth originate in the mantle. The liquid moves in a circle pattern as the hotter magma rises and the cooler magma falls. This can also be observed in any fluid material, gases or liquids.
What is the molten material under the earth's crust?
Magma
Is a material magma?
No. Magma is molten rock that has not erupted. After it erupts it may or may not form pyroclastic material depending on how explosive the eruption is.
What is the melted material beneath the Earth's surface?
This material is most often referred to as magma.
What kind of material does the composite volcano have?
Magma
What are the two kind of material?
Lava and Magma
