How can we measure the rate of seafloor spreading?

Measure from a spot at which the plate is spreading outward to a spot with a known age point. Use the map's scale to convert the measurement into actual inches of spreading over that time period. Divide the distance the sea floor spread by the time it took to spread that far, to find the rate of spreading per year.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
