To form a nebula,_____ pulls matter together or cause
it to clump.
gravity
To find the correct answer, we need to understand what a nebula is and how it forms.
A nebula is a vast cloud of gas and dust in space, often resulting from the explosion of a dying star. These clouds are the birthplaces of stars and planetary systems.
To form a nebula, there are two forces at work: gravity and energy. Gravity is responsible for pulling matter together, while energy, often from a dying star, causes the matter to expand and dissipate.
Based on this information, the correct answer would be gravity. Gravity pulls matter together, leading to the formation of a nebula.
