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.
Where does the oceanic crust begin?
The continental shelf is normally made out of continental crust, the oceanic crust begins at the base of the continental rise. However in most places the oceanic crust near the continental margins is covered by continental sediments (eroded form the continents) carried down onto the Oceanic planes by deep sea canyons running off the continental rises.
How do magnetic reversals provide evidence for sea-floor spreading?
The presence of magnetic domains of alternating orientation parallel to the plate boundaries.
How have scientists been able to able to study earth's mantle?
In some places, Earth`s crust thins enough to see mantle.
Places where new sea floor is being created?
New oceanic crust is formed when volcanic activity disrupts the seafloor at the mid- ocean ridge. When this occurs it is referred to as oceanic spreading.
Is magnetic stripes on the ocean floor the places where oceanic crust sinks back to the mantle?
it is right in your book soo... you should be able to answer this
Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?
Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle
What are places where oceanic crust sinks back the the mantle?
A "subduction zone".
Where are the places where oceanic crust sinks back into the mantle.?
A "subduction zone".
What are places where oceanic crust sinks back into the mantle called?
A "subduction zone".
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What is the process in which continents move?
Both continental plates and oceanic plates float on the top of the mantle. Convection currents in the mantle rock cause the top surface of the mantle to move in different directions in different places. The continental plates and oceanic plates floating on the top of the mantle are dragged along in the direction of motion of the top of the mantle directly beneath them.This process is part of the theory of plate tectonics, which explains many other things beyond the apparent movement of the continents.

What is it called when Earth's magnetic poles chang places?
This is known as magnetic reversal when earth's magnetic poles change places.
Where does the oceanic crust begin?
The continental shelf is normally made out of continental crust, the oceanic crust begins at the base of the continental rise. However in most places the oceanic crust near the continental margins is covered by continental sediments (eroded form the continents) carried down onto the Oceanic planes by deep sea canyons running off the continental rises.
Why is continental crust deeper than oceanic crust?
The oceans flow to the places where the crust is the lowest. Gravity causes them to flow downward. The mantle, below the crust, is at the same depth everywhere, so if the crust is lower, it is because it is thinner.
