Answer: A difference in properties between two interacting systems as explained below.
Explanation: Planetary differentiation is the process of separation of different parts of a planetary body as a result of their physical or chemical behavior.
Causes for Physical Differentiation:
1. Melting and crystallization of source rock.
2. Differences in densities
3. Thermal diffusion
4. Collision of large bodies
Chemical Differentiation accounts for differences in chemical compositions of different materials.
The differentiation, or organization, of the Earth into layers led to the formation of a core, a crust, and eventually continents. The light elements were driven from the interior to form an ocean and atmosphere.
Answer:
Explanation:
The horizontal distance traveled by the projectile is given by the formula
The formula for the time of flight is given by
Case I: when the launch angle is 30°
So, 
Horizontal velocity = u Cos 30 = 0.866 u
Case II: when the launch angle is 60°
Horizontal velocity = u Cos 60 = 0.5 u
By observing the case I and case II, we conclude that
R1 = R2
Horizontal velocity 1 > Horizontal velocity 2
T1 < T2
