Ocean-ocean convergent boundary (two oceanic plates converging). Ocean-continent convergent boundary (an oceanic and a continental plate converging). Continent-continent collision zone (two continental plates converging). All of the above should create a trench. Save sWriting one GEOS11.pdf Writing one GEOS1.pdfExplanation / Answer
1- Contiment-continent collision zone (two continental plates converging) Since no continental plate subduact due to low density and high buoyancy, so the is no trench in this setting.
2- All plate boundaries can produce earthquakes.
3- Japan(Mariana trench) it is formed by ocean-ocean subduction.
While Himalaya is continent-continent collision, San Andreas is transform plate boundary and the mid-Atlantic ridge is divergent boundary.
4- convergent boundaries with subduction ( in subduction zone one plate goes deep inside the earth so deep earthquakes are generated).
5-True are-:
The earth's outer coreis liquid, and we know this because s waves do not travel through the outer core.
The earth's mantle is mistly solid, and both p and s wave travel through the earth's mantle.
P- waves travel through solids and liquids, s- waves only travel through solids.
