Give two pieces of evidence for seafloor spreading?
Geographic similarities between continental margins on both sides of the Atlantic Ocean and similarity of strata and fossils found on those margins.
What is it called when two oceanic plates move apart and new crust is formed?
Seafloor Spreading
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.
Why seafloor spreading is like a moving conveyor belt?
because the two plates are pushing away from each other like a conveyor belt
What are two pieces of evidence that support the theory of sea floor spreading?
1) mapping of magnetic reversals 2) the nice fit you get by placing places like South America and Africa next to each other. ( &3) fossil evidence of both plants and animals.)

What is rorpsfgnloedaeasi unscrambled?
The anagram is two words: seafloor spreading.
What was the two discovery Harry Hess?
The Seafloor Spreading Theory
How magnetic reversal provides evidence for seafloor spreading?
The Earth's crust is broken into many slowly moving plates. Sea floor spreading occurs at the mid ocean ridge where two plates are moving away from each other. Magma rises up from below and cools to form new seafloor rock
What is deep sea trench?
a part of seafloor spreading where the deep sea splits in two
What two scientist proposed the theory of seafloor spreading in the early 1960s?
Alfred wegner

What Is the mechanism responsible for producing the new seafloor between two diverging plates?
Sea Floor spreading
Sea-floor spreading is a result of?
Seafloor spreading occurs when two tectonic plates move further away from each at mid-ocean ridges. In these ridges new crust is formed through volcanic activity and thus expanding the seafloor.
Place where seafloor spreading occurs?
Seafloor spreading occurs at the boundary between two tectonic plates. As the plates divide, magma comes up through the crack and cools to form new sea floor. The farther away the floor is from the boundary, the older it is.
