The statement is - True.

The avalanches are a very dangerous occurrence. They are very heavy, carry a lot of snow, and are also very fast, so for anyone on their way it is likely to end up very tragically.

The avalanches are essentially a downhill fast moving snow. They usually appear after 24 hours of when a heavy snow of over 12 inches fell. They mostly appear on very steep slopes. Because the large amount of snow brings in a lot of weight and pressure, and the steepness of the terrain can not support all that weight and pressure in one place, the snow starts to move. The movement is sudden, with the snow managing to accelerate to 80 mph/h in just 5 seconds.

Which of the following statements correctly explains the tectonic plate activity on the west coast of the united states?.

The statement which correctly explains the effect of tectonic plate activity on the west coast of the United States of America is that: Earthquakes occur at the San Andreas Fault when stored energy is released from locked plates.

A tectonic plate is also known as lithospheric plate and it can be defined as an enormous, solid, irregularly shaped rock slab, that is made up of two (2) main plates:

Oceanic plates

Continental plates

According to the theory of plate tectonics, the arrangement of continents, oceans, volcanic activity, earthquakes, and the formation of landforms such as mountains, are caused by the movement of tectonic plates over millions of years.

In this context, the effect of tectonic plate activity on the west coast of the United States of America is that earthquakes would take place at the San Andreas Fault when the energy stored in locked plates are released, as shown in the image attached.
