Question

1. choose the best answer. without the ____ of the sun, there could be no life on earth. gravity rotation heat and light mass

Explanation:

To determine the correct answer, we analyze the role of the sun in supporting life on Earth. Life requires energy in the form of heat and light for processes like photosynthesis, temperature regulation, and sustaining ecosystems. Gravity (of the sun) keeps planets in orbit but isn't directly about life - supporting energy. Rotation (of the sun) isn't the key factor for Earth's life; it's the sun's emission of heat and light. Mass (of the sun) is related to gravity but not the direct provider of life - enabling energy. So "heat and light" is the correct choice.

Answer:

B. heat and light (assuming the options are labeled with letters, but based on the visual, the second option "heat and light" is correct)
