Tsunamis are large and powerful ocean waves generated when earthquakes occur in the ocean. as evidenced by the picture, tsunamis can cause immense amounts of damage. why are tsunamis so destructive?
a) tsunamis carry material from the ocean which causes damage when they collide with land.
b) tsunamis often damage power plants, releasing energy that causes most of the destruction.
c) earthquakes deep under the ocean's surface are associated with volcanoes, tsunamis transmit this super-heated water to land.
d) when tectonic plates move against each other they generate large amounts of seismic energy which is transmitted by the waves of tsunamis.

D) When tectonic plates move against each other they generate large amounts of seismic energy which is transmitted by the waves of tsunamis

Explanation:

Tsunamis or tsunamis are gigantic waves that have a large volume of energy and that occur in the oceans.

These waves are caused by the movement of tectonic plates located below the oceans. The denser ocean plates slide under the continental plates which are less dense, in a process that is called subduction.

These marine earthquakes, also known as tidal waves, displace a large amount of water, forming one or more waves (tsunamis) that can reach the coasts of the oceans, causing catastrophes.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
