Question

Quizplus · Accepted Answer

The solar constant is a measure of the amount of energy received per unit time per unit area at the location of Earth, specifically just outside its atmosphere. Therefore, choice B is the correct option. Choice A is incorrect because it only accounts for energy received on Earth's surface, whereas the solar constant refers to the amount received just outside the atmosphere. Choice C is incorrect because the solar constant specifically relates to Earth's location, not any other location in the solar system. Choice D is incorrect because it refers to the energy emitted by the Sun, not the energy received by Earth. Choice E is incorrect because it refers to the total energy emitted by the Sun in all directions, regardless of whether it is received by Earth or not. The solar constant is defined as the amount of solar radiation that arrives at a specific area near Earth's upper atmosphere. It is measured in watts per square meter (W/m²). Therefore, it is a measure of the energy received from the Sun at the location of Earth.
