Magma can partially crystallize at depth and then rise to shallow depths where the remaining magma solidifies. the early-formed crystals are phenocrysts and the texture is porphyritic. in Lava or near the earth surface,very large crystals can grow, forming intrusive rocks or volcanic rocks . magma that cools in <span>shallow magma chambers </span> has a relatively short time to cool and so forms <span>fine grained rocks </span>, but not volcanic glass. in deep magma chamber, magma cools at a slow rate, allowing the formation of extrusive or plutonic rock .
<span>The answer is 4, 6 and 7. Gas and plasma share most similar properties. The difference lies in the fact that plasma is composed of ions and electrons (ionized gas) as opposed to gas that is composed of neutral molecules. Therefore plasma can conduct electricity while gas cannot. </span>
Answer:
Explanation:
His Kinetic energy = 1/2 m v^2
v = 5 m/s
m = 75 kg
Ke = 1/2 75 * 5^2
Ke = 937.5 Joules
This will be converted to PE when he reaches the maximum height he reaches. In other words KE = PE
PE = m * g * h
m = 75
g = 9.81
h = ?
PE = 937.5
937.5 = 75 * 9.81 * h
937.5 = 735.75 * h
937.5/735.75 = h
h= 1.27 meters
A light-year is a unit of distance.
The definition of a light-year is the distance light travels in one year.
