Why do new stars form from a hydrogen gas and dust clouds? Be sure to discuss the role of gravity and fusion in your explanation. Include evidence to support your claim.

New stars are able to form from hydrogen gas and dust clouds because the hydrogen gas and dust clouds allow for a new star's fuel.

Gravity allows for the hydrogen gas and dust clouds to condense into a star form. With more and more hydrogen gas and dust clouds combining, the pressure increases and the condensing becomes heavier and heavier. The pressure allows for fusion to start occurring.

Once hydrogen gas and dust clouds have finished condensing, the fusion will still be present. The fusion of hydrogen (fuel) into helium (product) allows to the star to emit light and heat.

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
