Answer:
The best and most correct answer among the choices provided by your question is the fourth choice or letter D "The thin membrane that closes the cavity of the middle ear from the outside changes position."
Your ears pop in airplanes because the air high above the surface of Earth is less dense than air near the surface, because air near the surface has all the air above it pushing down. Your inner ear has air trapped in it and as the atmospheric pressure changes, it causes pressure on your eardrum.

Explanation:
Uplift occurs are converging tectonic plate boundaries and at faults with compressional forces. As two tectonic plates collide, usually, the continental plate os folded due to the pressure hence causing uplift. At reverse faults, the compression causes the earth’s crust to uplift causing a hanging wall over the footwall.
Subsidence also occurs at convergent plate boundaries. The oceanic plate is usually the one that subsidies under the tectonic plate during the collision because it is heavier. SUbsience also occurs at normal faults where the two crust moves away from each other causing a chunk of the crust to subside. The hanging wall goes lower in elevation in comparison to the footwall.
Answer:
Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.

Decomposers, as their name strongly suggests, decompose matter, more specifically dead matter and waste materials. These decomposers break down the dead body of the once living organisms and the living organisms' waste materials to their basic state and disposition. </span>
