questions

• what is gravity?
• what caused the sun to form?

Explanation:

The questions "What is gravity?" and "What caused the sun to form?" are related to understanding natural phenomena. Gravity is a fundamental force in physics, and the formation of the sun involves astrophysical and physical processes. So the subfield of Natural Science that best applies is Physics (as gravity is a key concept in physics and the sun's formation is studied in astrophysics, a branch of physics).

Answer:

Natural Science - Physics
