In ridge push, the mantle wells upward because of the
convection and elevates the edges of spreading oceanic plates. Because these
plates are higher at the spreading center, they are forced downhill due to
<em>gravity</em> and eventually flatten out to the ocean floor.
Maybe b might be the answer
Answer:
B. a substance that can accept a proton from an acid
Explanation:
Johannes Brønsted and Martin Lowry independently developed definitions of acids and bases based on compounds abilities to either donate or accept protons (H+ ions).
The acid is the donor of the hydrogen ions while the bass is the acceptor of the hydrogen ions.
Back to the options, the correct option is B. Which is a substance that can accept a proton from an acid. All other options are incorrect.
