Lots of water will evaporate very fast and the mantle's compositions would harden and solidify to become part of a new sea floor. This is what scientists call 'sea-floor spreading'.
What else can I help you with?
Does The mantle of the earth continually heats up and cools down using convection currents?
Yes, the mantle of the Earth heats up and cools down due to convection currents. Heat from the Earth's core drives convection currents in the mantle, causing hot material to rise and cool material to sink. This movement transfers heat throughout the mantle, driving plate tectonics and volcanic activity.
Area in the Earth's mantle hot enough to melt rock into magma and create volcanoes?
All of the Earth's mantle is hot. And while some geologists believe that there are Mantle plumes (or hot spots) current evidence seems to support a view that mantle plumes do not exist. What causes magma to rise up from the lower crust and mantle is the convection of the mantle and therefore the places where most heat (and magma) is coming up to the surface is along the mid oceanic ridges.
What happens to this crust as it is pushed down into the mantle?
As it is cold and wet, it continues to sink and slowly heats up. This causes partial melting and it acts as a source of magma for volcanoes that form above it. so does other people burn when the go into mantle?
What happens in the mantle?
One of the most significant events that takes place in the mantle is the heat transfer in the form of convection cells. In other words, heat (generated by the core) circulates throughout the mantle and that drives the movement of the tectonic plates.
How does subduction create mountains?
Subduction occurs when one tectonic plate slides beneath another. As the descending plate moves deeper into the Earth's mantle, it heats up and releases water and gases. This causes the overlying plate to melt and form magma, which rises to the surface and creates volcanic activity. The accumulation of this magma and the compression of the overlying plate lead to the formation of mountains.
What happens when the hot core heats the lower mantle?
Lower mantle heats up, rises out to the crust/upper layers of earth, cools down, then circulates back to the core, heats back up, rises, etc. (circulates like ocean currents)
What happens when two tectonic plates move apart?
Magma seeps up through the two plates from the mantle and form volcanos.
What is the mantle and crust made up of?
Nearly all of the mantle and crust are made up of rock, and in the case of the mantle, a small percentage of magma (melted rock).
What might happen on earth surface if magma rises in a convection current?
Most convection currents exist in the mantle, the layer below the Earth's crust. As the semi-molten rock heats up, it rises closer to the surface as magma and hence cools on the earth surface to form rocks.
Does The mantle of the earth continually heats up and cools down using convection currents?
Yes, the mantle of the Earth heats up and cools down due to convection currents. Heat from the Earth's core drives convection currents in the mantle, causing hot material to rise and cool material to sink. This movement transfers heat throughout the mantle, driving plate tectonics and volcanic activity.
What layers makes up most earths mass?
The Mantle. It is the largest and thickest layer in the earth. But this answer might not be actually true. Because the earth has all these layers and the mass is added up. -By Olivia Agbo A 12 year old. Thank you for your support.
Where lava comes out of a volcano?
Lava is the name given to magma which has been erupted onto the earth's surface. Magma in turn forms by the partial melting of material in the upper mantle, usually caused by either the release of "volatiles" - water / gases etc into the mantle from a subducting slab of oceanic crust which acts to lower the temperature at which it will melt or by decompression melting of up welling mantle material.
Is the Mantle made up of liquid or solid magma?
The mantle is made up of solid rock, specifically solid mantle rock in the upper part and more ductile solid rock in the lower part. Magma is only present when it is partially molten rock that forms in specific regions of the mantle.
What do you think happens when some air heats up and other air is cool?
What do you think happens when some air heats up and other air is cool?
Why doesn't the lava in the mantle harden?
Lava is the mantle is called magma. Lava, referring to magma that is flowed out onto Earth's surface, only hardens when the temperature around it drops. This is because lava is very hot, and when the temperature drops, it cools and solidifies due to its thixotropic and shear thinning properties, just like clay. Magma is actually kept in its liquid state because of the temperature of the mantle, which ranges from 500°C to 4,000°C. The magma itself in the mantle is approximately 700°C to 1300°C, which means that the temperature is not low enough for magma to harden. Magma is part of the convection process occurring inside the mantle. Since the mantle closer to the core is of higher temperature than when closer to the crust, there is a convection process where magma heats up from the hotter core side and rises to the cooler crust side and vice-versa. Thus, just like when you keep mixing clay, the moving magma in the mantle will not harden.
What happens to a liquid when energy is added?
it heats up
What of the earth is made up of magma and is found just beneath the earth's crust?
The mantle.
