Только 3 . к границам литосферных плит приурочена сейсмические пояса

Answer 2

The Correct Statement about Lithospheric Plates

The correct statement about lithospheric plates is that seismic belts are associated with the boundaries of lithospheric plates.

Lithospheric plates are large, rigid pieces of the Earth's outermost layer, known as the lithosphere. These plates float on the semi-fluid asthenosphere beneath them. The movement and interaction of these plates give rise to various geological phenomena, such as earthquakes, volcanic activity, and the formation of mountain ranges.

Seismic belts, also known as earthquake belts, are regions where a large number of earthquakes occur. These belts are closely associated with the boundaries of lithospheric plates. The movement and collision of plates along these boundaries can generate significant seismic activity.

It is important to note that the other statements provided in the question are not accurate:

- The collision of lithospheric plates does not form extensive plains. Instead, it often leads to the formation of mountain ranges, such as the Himalayas, when two continental plates collide.

- The structure of continental and oceanic lithospheric plates is not the same. Continental plates are thicker and less dense than oceanic plates. Continental plates are composed of granitic rocks, while oceanic plates are primarily made up of basaltic rocks.

- The boundaries of lithospheric plates do not exactly coincide with the outlines of continents. While some plate boundaries do align with continental margins, others occur within the oceanic crust or even within continents.

To summarize, the correct statement is that seismic belts are associated with the boundaries of lithospheric plates.
