Analyze driving forces of plate tectonics

The theory of Plate Tectonics explains that lithospheric plates move over the asthenosphere. This motion is driven by thermal convection currents in the mantle. The source of energy that heats the mantle and drives these currents is the Earth's interior heat, which comes from radioactive decay and residual heat from Earth's formation.

Identify factors increasing weathering rates

Weathering is the breakdown of rocks at Earth's surface. Humidity (moisture) accelerates chemical weathering. High temperatures speed up chemical reaction rates. Chemical exposure, such as acid rain, directly dissolves minerals. Therefore, all of these factors increase the rate of weathering.

Evaluate statements about plate boundaries

Plate boundaries are dynamic regions where tectonic plates interact. While rapid changes do not always occur and plates do not only converge, these boundaries are highly associated with geological activity. Volcanic activity, faulting of Earth's surface, or earthquakes are highly likely to occur at plate boundaries.

Determine processes of surface weathering

Earth's surface is weathered through physical, chemical, and biological processes. This includes physical and chemical interactions with living organisms (biological weathering), water movement of rivers, streams, and oceans (physical/chemical weathering), as well as wind, precipitation, and severe storm events. Since all three options describe valid weathering processes, they are all correct mechanisms.
