Answer:
7. Tsunami
— A tsunami is a series of ocean waves with very long wavelengths (typically hundreds of kilometres) caused by large-scale disturbances of the ocean, such as: earthquakes.
8.Volcanoe islandarc
— The magma produced by this mechanism varies from basalt to andesite in composition. It rises upward to produce a linear belt of volcanoes parallel to the oceanic trench, as exemplified in the above image of the Aleutian Island chain. The chain of volcanoes is called an island arc.
9. Mountain
— A mountain is a large landform that rises above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally considered to be steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth.
10. Convergent Boundaries
— Convergent boundaries occur where two plates slide towards each other to form either a subduction zone (if one plate, normally an oceanic plate moves underneath the other) or a continental collision.
