This question is based on the Subduction Zones topic in the Tsunami Initiation Animation. Click here to access it. 1st attempt The initiation of a tsunami by a stick-slip subduction zone is similar to the motion experienced by which type of fault? Choose one: A. strike-slip fault B. normal fault C. reverse fault D. transform fault

C. reverse fault

Explanation:

Most tsunamis are formed by subduction zones that cause earthquakes from the movement of one tectonic plate over the other, below the ocean, promoting the movement of overlapping water. The friction between the plates causes an extensive accumulation of energy that increases to the point of extrapolating the limit between the two plates. In this process, when the initiation of a tsunami through a stick-slip subduction zone is similar to the movement experienced by a reverse failure.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
