Which process is the most significant contributor to the generation of internal heat within the Earth, and how does it affect mantle convection? Mark only one oval.

• Gravitational compression during Earth's formation; it creates convection currents by increasing pressure in the mantle.

• Frictional heating from tectonic plate movement; it directly powers mantle convection by increasing the temperature at plate boundaries.

• Radioactive decay of unstable isotopes such as uranium-238, thorium-232, and potassium-40; it generates heat that drives mantle convection and influences plate tectonics.

• Heat from the Earth's core resulting from residual formation energy; it directly heats the mantle, leading to convection currents without the need for radioactive decay.

Which statement accurately describes the differences in density and temperature between Earth's layers, and how these differences affect geological processes? Mark only one oval.

• The crust has the highest density and lowest temperature, leading to the formation of mountains through isostatic adjustment.

• The mantle has a uniform density and temperature throughout, resulting in consistent rates of plate movement and volcanic activity.

• The outer core is less dense than the mantle but hotter, driving the Earth's magnetic field through the movement of molten iron.

• The inner core is the most dense and hottest layer, creating convection currents in the mantle that drive plate tectonics.

What is the primary difference between P-waves and S-waves? Mark only one oval.

• P-waves travel only through liquids, while S-waves travel only through solids.

• P-waves are slower than S-waves and can move through both solids and liquids, while S-waves are faster and only travel through solids.

• P-waves travel faster than S-waves and can move through both solids and liquids, while S-waves are slower and only travel through solids.

• P-waves and S-waves travel at the same speed but through different materials.
