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 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?
Does The mantle of the earth continually heats up and cools down using convection currents?
Yes, the mantle of the Earth continually heats up and cools down using convection currents.
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.
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.
Describe the convection currents that occur inside Earth?
Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global scale flow of magma.

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.
Does The mantle of the earth continually heats up and cools down using convection currents?
Yes, the mantle of the Earth continually heats up and cools down using convection currents.
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.

Does the magma and lava from a volcano come from the mantle?
Yes it does , The magma finds gaps through the crust ( oceanic or continental) and comes up as a volcano. It is originally in the mantle.
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).
How do volcanoes errupt?
Volcano's errupt from the magma from the mantle making it's way up to the surface, or A hole in the mantle making a magma chamber deep inside the volcano. And when it gets very high pressure then it errupts according to magma composition either it is acidic or basic in nature.
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.
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.
