Sea-floor spreading was a key discovery because it showed?
that mid-ocean ridges have rifts at the center.
Are convergent boundaries and sea-floor spreading related in any way?
No, but divergent boundaries are the spreading of the sea floor and convergent boundaries are tectonic plates push together
A mid-ocean ridge forms at what type of plate boundary?
A mid-ocean ridge forms at the divergent plate boundary. This boundary initially forms rifts that later on become rift valleys.
What happens at spreading boundaries?
When a spreading boundary develops on land, two slabs of Earths' crust slide apart. :D :ID (c:
A rift valley forms at a spreading boundary which is?
diverg
Divergent plate boundaries are characterized by what?
Rifts.
What happens along divergent boundaries?
along divergent boundaries tectonic plates move apart & rifts are created
What are spreading boundaries?
Spreading boundaries are places where two plates move apart.
What is the landform type where divergent boundaries take place?
Oceanic or continental rifts.
What forms when continental plates pull apart at divergent boundaries on land?
On land, this forms a rift valley. When the surface is submerged, it is called seafloor spreading.
What occurs at plate boundaries that are associated with seafloor spreading?
When seafloor spreading happens, a rift forms at the bottom of a ocean and separates to form new rock. This is an example of a divergent plate boundary
What three features can be found at divergent boundaries?
Rifts Mid-oceanic ridges Volcanic islands

Are convergent boundaries and sea-floor spreading related in any way?
No, but divergent boundaries are the spreading of the sea floor and convergent boundaries are tectonic plates push together
How are spreading boundaries related to volcanoes?
they are not
Is the place where two tectonic plates move away from one another?
mid - ocean ridges, they're caused by divergent boundaries Rifts are also on land, such as the Great Rift Valley in Africa mid - ocean ridges, they're caused by divergent boundaries Rifts are also on land, such as the Great Rift Valley in Africa mid - ocean ridges, they're caused by divergent boundaries Rifts are also on land, such as the Great Rift Valley in Africa
How does subduction is opposite of spreading boundaries?
it is opposite because subdution sinks in the earth crust and back up and spreading boundaries spread appart.
