Answer:
Chemical differentiation
Explanation:
The process by which minerals crystallize out of magma is termed chemical differentiation. Some times, it is referred to as magmatic differentiation.
- Minerals have different properties and at certain environment, it comfortable for the settle out of magma.
- Some minerals can crystallize out at very high temperature.
- Some will form at medium temperature whereas, some are low temperature minerals.
- Based on the properties of the minerals in a melt, a minerals will differentiate at various temperature and pressure regimes.
Answer:
250 light minutes takes
Explanation:
1 astonomical unit is equal to 1.50x10¹¹m
The light travels at the speed of 3.0x10⁸m/s. That means in 1 second, travels 3.0x10⁸m. To solve this question we must find the distance of neptune to the sun in meters. In this way we can find the seconds (And minutes) that need the light to travel from the sun to neptune:
<em>Distance from Sun to neptune:</em>
30AU * (1.50x10¹¹m / 1AU) = 4.5x10¹²m
<em>Time transcurred:</em>
4.5x10¹²m * (1s / 3.0x10⁸m) = 15000s
15000s * (1min / 60s) =
<h3>250 light minutes takes</h3>
