How does seafloor spreading explain continental drift?
Seafloor spreading is caused by two plates moving apart. This is caused by plate tectonics. Continental drift is also caused by plate tectonics. Therefore, we can conclude that continental drift is related to seafloor spreading. When the plates move, it carries the continents with it, and thus the continents drift away from each other.
What structure on the seafloor would have magnetic striping?
astherosphere
The oldest rocks on the seafloor are much younger than the oldest rocks on the continents?
true
How does seafloor spreading affect us?
seafloor spreading affects us with help from continental drift. seafloor spreading creates new seafloors, but moves the continents a few centimeters apart from each other every year. in many years, pangaea will become aeagnap, because the continents will become one big land again, but backwards, and will damage the faults and the only land we have severely.
How do magnetic signatures support the idea that continents move?
Scientists indicated that the seafloor was spreading, so the poles "reverse"

What is the idea that continents have moved horizontally through the seafloor to their current locations?
seafloor spreading by Harry Hess
What does seafloor spreading have to do with the theory of continental drift?
Seafloor Spreading helped move the Continents to their current location.
Why are there fewer large impact craters on the Earth's seafloor than on the continents?
The seafloor crust is younger than the continental crust.
What caused the continents to rise from the seafloor millions of years ago?
floaties
Are all plate boundaries located along the margins of continents?
No. Many plate boundaries are on the seafloor far from continents and several are well within continents.
What primary force that causes the seafloor to spread and continents to drift?
Geothermal Drift.
What structure on the seafloor would have magnetic striping?
astherosphere
The oldest rocks on the seafloor are much younger than the oldest rocks on the continents?
true
How did the continents move from pangaea to their current location?
by the wegner theory that seafloor spreading is going on
Why can't someone feel the seafloor spreading?
We can't feel seafloor spreading because the ocean is super deep that the continents will not shake or burst in somewhat actions.
What is a seventeen letter word for a primary force that causes the seafloor to spread and continents to drift?
thermal convection
