Answer:
Normal faults,
Explanation:
Large normal faults allow blocks of crust to be displaced downward, forming a rift.
Basaltic lava erupts within the rift forming pillow ba salts on the seafloor. Other magma solidifies within fissures, forming di kes . As the crust cools, it subsides and is covered by ____________ , which tends to smooth over any rough topography. As two oceanic plates move apart, rock and magma in themantle rise to occupy this space.
Large normal faults allow blocks of crust to be displaced down ward, forming a rift.
Basaltic lava... the rift forming pillow basalts on...
Other magma solidifies... forming di kes.
As the crust... by sediment,...
As two oceanic plates... in the mantle...
Basaltic lava is a molten rock made of iron, silica and magnesium.
Because of its low presence of silica, it is very runny.
When the magma solidifies, it creates di kes.
As the crusts become cools down, it forms sediments.
The movement of plates creates space, which led magma to rise in the mantle and erupts to the surface.
Therefore, we can conclude that the eruption causes many changes in the lave as it appears in surface.
