What effect does convection currents in the upper mantle have on the crust?
Convection currents in the mantle create plate tectonics.
How do plates move where convection currents are risig?
The lithosphere is the continental crust, oceanic crust and upper part of the mantle. The convection currents move in the mantle mostly in the Asthenosphere layer under the lithosphere. As the convention currents move it makes the lithosphere spread and shake.
What are some effects convection currents have on the world?
Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.
How does oceanic crust form at constructive plate margins?
Do you mean spreading centres or oceanic ridges, where the oceanic lithosphere is renewed by hot, less dense rock rising in convection zones.
Can movement of tectonic plates cause oceanic currents?
yes...it affects a lot.....
What effect does convection currents in the upper mantle have on the crust?
Convection currents in the mantle create plate tectonics.
What causes the oceanic lithosphere to move away from the mid-ocean ridge?
it is caused by convection currents

How do you contrast mid-ocean ridges and trenches?
Mid-ocean ridges are the birthplace of oceanic crust. Trenches represent the destruction and burial of oceanic crust. They are at opposite ends of the Earth's convection currents that move through the asthenosphere.
Where do you find convection currents?
Convection currents occur in the asthenosphere.
In the mantle and core make tectonic plates move?
Convection currents in the mantle and core make tectonic plates move. The continental crust of the Earth is thicker and lighter than the oceanic crust.
What do you call the section of the lithosphere over the asthenosphere that carries continental and oceanic crust?
it is not magma srry guys who read this earlier it is i think convection currents thats wat my school website says so ya.
What does ocanic mean?
It seems like there might be a typo in your question. It's possible you meant to ask about the word "oceanic," which typically refers to things related to or characteristic of the ocean, such as oceanic currents, oceanic fauna, or oceanic climate.
Do oceanic electric fields produce electric currents?
Yes
How plate tectonics move?
== == The main features of plate tectonics are: * The Earth's surface is covered by a series of crustal plates. * The plates are composed of crustal rock and solid upper mantle which is called the lithosphere. * Plates are composed of continental and oceanic crust. * The oceanic crusts are continually moving, spreading from the center, sinking at the edges, in a process of recycling. * Rising legs of convection currents beneath the plates create additional plate material at mid-ocean ridges, sinking legs of convection currents swallow old crustal plates at subduction zones. * The heat driving the convection currents is from radioactive decay of material within the Earth and from residual heat from accretion processes during Earth's formation. Convection cells in the magma of the outer core pull the earth's tectonic plates along the surface. These plates can collide and cause earthquakes.
What causes the plates to move and the sea floor to spread?
Convection Currents: The difference in temperature between the upper and the lower mantle creates these currents that causes magma to rise up through the mantle and out the crust.
