What parts are youngest on earth's crust?
Directly along active oceanic ridges, such as the mid-oceanic ridge in the Atlantic (which Iceland straddles) and on active volcanoes, such as Hawaii. When lava from volcanoes such as Hawaii and the mostly undersea volcanoes of mid-oceanic ridges cools, it solidifies into brand new rock.
How are mid-ocean ridges and seamount relates to volcanoes?
Mid-ocean ridges and seamount relates to volcanoes by both having lava and it also comes out and cools
Which type of volcanism produces the most lava annually?
Diverging plates or rift volcanos product the most lava annually.
When two oceanic plates diverge?
Volcanoes form from the exposure of lava in the Earth's mantle. B Actually this is wrong, it forms a mid oceanic ridge. Do some more research next time. C. Actually it forms a Mid-Ocean Trench both of you do better reserch next time.
What plate boundary are volcanoes formed at?
Volcanoes can form at three places-1. Divergent boundaries2. Convergent boundaries (oceanic-oceanic and oceanic-continental)2. Above hot spots

What type of lavas are erupted at mid-oceanic ridges?
The lavas erupted from mid-oceanic ridges are called basalts. This lava contains quarts, feldspathoid, and plagioclase. Basalts has gray to black color.
What do the words magma and lava name?
Magma is molten rock deep below the surface of the Earth. Lava is the same stuff when it comes to the surface from a volcano or mid-oceanic ridge. NOW... LOOK UP "mid-oceanic-ridge" AND learn something wonderful! JCF

What is called when lava from undersea rift zones produces volcanoes and mountain chains?
mid ocean ridges
What type of magma forms at mid-ocean ridges?
pillow lava named that because when it cools it looks like pillows.
What types of faults are most common along divergent plate boundaries?
Oceanic-oceanic plate divergence, such as that occurring at the mid-ocean ridges.
Do volcanoes form along mid ocean ridges where two plates move together?
Volcanoes that form along a mid-ocean ridge are called volcanic islands. These volcanoes occur when the plates move apart to produce gaps which molten lava rises to fill.
What types of volcanoes are formed at spreading centers?
Volcanoes at spreading centers is referred to as spreading center volcanism. This usually takes place on mid-oceanic ridges where the plates diverge.
