The correct answer is <span>D. They break down dead organisms</span>
The two basic factors which are most important in determining the current appearance of a star are its mass and its stage of life. Stars are born with 75% Hydrogen and 25% Helium, with no more than 3% of that being heavier elements. A star burns its supply of elements over its lifetime, the larger the mass of the star then the greater it's brightness, luminosity and surface temperature will be. Dependant on the stage of the star's life, the color of the light will change.

Answer:
Rock that is cooled and solidified above ground is called as extrusive.
Explanation:
The extrusive rocks is an type of igneous Rock. They are produced through the crystallisation process of the molten silicate material that comes out to the earth's surface during the volcanic eruptions.The rocks present below that mantle is melted due to high temperature and the molten magma is pushed out due to high pressure. This magma on reaching the earth's surface cools down rapidly forming extrusive rocks. Rhyolite, andesite are some examples of extrusive rocks. Extrusive rocks contains very few grains that are larger in size
