Question

Before a star is a star, it is an enormous cloud of gases. At the start, wisps of gas and drifts of dust collect, their gravity drawing them together. As more stuff gathers, its combined gravitation grows stronger. Eventually, the cloud pulls itself into a massive ball of material.

Describe the cause-and-effect relationships in this passage that lead to the formation of a star.

Answer 1

Cause: Wisps of gas and drifts of dust collect

Effect: The cloud's gravitation grows and pulls itself into a massive ball of material

Answer 2

Gravity causes gas and dust to come together. More gas and dust combining causes the gravitation to strengthen. The stronger gravitation causes a massive ball of material that eventually becomes a star.
