Answer:
The term that defines masses of rock, earth and/or debris that flow downhill is landslide (option D).
Explanation:
When a landslide occurs, a certain amount of the mass of earth is detached or displaced downwards, due to the instability present in a certain area, especially when there is a slope in that land or slope
.
The area that is unstable is usually in proximity to a stable ground zone, over which the slide occurs. The instability produced by the phenomenon is due to the fact that this ground has reached its maximum tangential tension.
<u>In a landslide, the movement of rocks, debris and everything in the strip of land that slides can also be observed</u>.
The other options are not correct because:
<em> A. </em><em><u>Tsunami</u></em><em> is the term for tidal wave, which impedes the displacement of large bodies of water, like waves, that reach the continent.
</em>
<em> B. </em><em><u>Aftershock</u></em><em> is the term that defines the seismic movements after an earthquake.
</em>
<em> C. </em><em><u>Liquefaction</u></em><em> of the earth implies that a compact terrain loses strength and becomes semi-liquid.</em>
