Seafloor Spreading Flashcards
1
Q
- process that occurs at mid-ocean
ridges, where new oceanic crust is formed through volcanic
activity and then gradually moves away from the ridge.
A
Seafloor Spreading
2
Q
basins that develop along the active boundary of
subduction zones.
A
Foreland -
3
Q
- older parts of the oceanic crust that were
smoothed due to sediment deposition.
A
Abyssal Plains
4
Q
- deepest parts of ocean basins (due to
subduction of oceanic crust.
A
Deep Sea Trenches
5
Q
- typical rift system that consists of rift arms
at approximately 120-degree angles
A
Triple Junction
6
Q
- is the flooded edge of the continents
A
Continental Shelf
7
Q
- is the edge or border region of the
continent.
A
Continental Margin
8
Q
Seafloor at subduction zones is destroyed
A
when a new one
is created.
9
Q
Rocks of the ocean floor considered as geologically young
A
as they are constantly subducted and recycled into the
Earth’s mantle.
10
Q
The capacity decreases,
A
during times of active seafloor
spreading.
