Question

a the heat that drives mantle convection comes from the sun and is absorbed by earths surface. b the primary source of heat for mantle convection is the radioactive decay of unstable isotopes in the crust and mantle, which causes density - driven motions. c friction from tectonic plate collisions, due to varying densities, generates heat that drives mantle convection. d heat from the inner core spreads outward through the mantle, driving mantle convection and tectonic plate movements. question 7 the following table contains information on landforms. landforms type formed by details himalayan mountains convergent boundary converging plates carrying 2 continents mariana trench convergent boundary subduction 2 oceanic plates peru - chile trench/andes mountains convergent boundary subduction oceanic and continental plates east pacific ridge divergent boundary separates nazca plate from pacific plate san andreas fault transform boundaries north american plate sliding past pacific plate which can be inferred from the information in the chart about boundaries? a trenches form at divergent boundaries. b underwater ridges form at transform boundaries. c faults form only at convergent boundaries. d mountain ranges form at convergent boundaries.

Explanation:

The table shows that Himalayan Mountains and Peru - Chile Trench/Andes Mountains, which are mountain - range related landforms, are formed at convergent boundaries. Option A is incorrect as trenches form at convergent boundaries, not divergent. Option B is wrong since underwater ridges form at divergent boundaries, not transform. Option C is false as faults can form at different types of boundaries, not just convergent.

Answer:

D. Mountain ranges form at convergent boundaries
