Why are intrusive rocks coarse-grained and extrusive rocks fine-grained?.
densk [106]

Answer:

Explanation:

Because extrusive rocks cool quickly, they only have time to form very small crystals such as basalt or none at all. On the other hand, intrusive rocks grow larger crystals because they take longer to cool. Extrusive rocks are usually fine-grained or glassy while intrusive rocks are coarse-grained.

Arisa [49]

Answer:

If a penny represents one years, 4.54 billion pennies are needed to represent the age of the Earth.

Explanation:

The equivalent number of pennies is the age of the Earth divided by the age of a penny. That is:

n = \frac{4.54\times 10^{9}\,years}{1\,\frac{year}{penny} }

n = 4.54\times 10^{9}\,pennies

If a penny represents one years, 4.54 billion pennies are needed to represent the age of the Earth.
