Praxis 5005 Practice Test Practice Question
Which TWO of the following are powered most directly by the Sun's energy?
Correct Answer: A,D
Rationale: Surface currents in the ocean and convection in the atmosphere are both driven primarily by the Sun's energy. The Sun heats the ocean's surface, creating temperature gradients that generate currents, while solar radiation warms the Earth's surface, leading to convection currents in the atmosphere.
In contrast, volcanic eruptions and tectonic plate movements are primarily driven by internal geological processes. Volcanic eruptions result from the Earth's internal heat, while tectonic plate movements are caused by forces such as mantle convection and gravitational pull, rather than solar energy.
