When a mass increases, its gravitational force
A. Increases
B. decreases
C. stays the same

A) Increases

Explanation:

There will be more gravitational pull since there is more mass.

The answer is A

Explanation:

The gravitational force between two objects depends on 2 factors,mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases!!

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
