Question

Accretion was one of the processes responsible for heating up Earth’s core in the early years of the solar system. WHICH TWO!! observations can be made about the process of accretion?
A.) Gravity increases as mass increases.

B.) There is little or no transfer of energy.

C.) Frequency of collisions increases as gravity increases.

D.) Intensity of impacts decreases as gravity increases.

E.) Heat energy decreases as gravity increases.

Answer 1

Answer:

A.) Gravity increases as mass increases.

C.) Frequency of collisions increases as gravity increases.

Explanation:  

The heating of core of Earth was due to accretion process and some other factors.

Accretion is the process in which particles accumulate due to force of gravity and grow into a massive object. As the mass increase, so does the gravity. The frequency of collisions increases. Particles collide and stick with each other. This generates large amount of heat.

Answer 2

A and C are your answers i think.
