Complete question: (Note: I failed to find the exact same question with its options, so I included many possible statements about convection)

The mantle is the layer in which convection occurs causing the crust to move. Which statement below best describes the convection currents in Earth's mantle?

They transfer potential energy away from Earth's core toward its crust. They transfer thermal energy away from Earth's core toward its crust. They transfer chemical and thermal energy in a circular pattern.

Explanation:

The convection currents are the result of heating by temperature gradients. Differences in temperature and density produce these currents. Warm materials are lighter and can ascend, while cold materials are heavier and denser, so they tend to descend. These materials movements create a circular motion pattern known as convective currents. They occur in the atmosphere, in the water, and the earth´s mantle.

In the last case, while the hot mantle emerges from the deepest areas, the cold mantle sinks, creating a circular convection current. These play an important role in fluids circulation and might be responsible for the movements of the lithospheric plates that are over the mantle. The temperature in the oceanic lithospheric plates is much inferior to the mantle´s temperature, so the lithospheric pieces sink, creating a descendent current.

Near the terrestrial core, the temperature might reach up to 3,500ºC, and solid materials in these areas melt and fuse. When fusing, materials lose density, becoming lighter and ascending again to the surface, creating the ascending currents. The currents of ascending materials are known as thermal feathers or plumes.

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
