Question

Lava that cools so quickly that ions do not have time to arrange themselves into crystals will form igneous rocks with a
A. porphyritic texture.
B. coarse-grained texture.
C. glassy texture.
D. fine-grained texture.

Answer 1

 glassy texture as seen in the block based game minecraft...

Answer 2

Answer: Option (D)

Explanation: Magmas when comes out of the surface, then it is known as lava and this lava immediately solidifies, and forms igneous rocks. The crystal's size and texture depends upon the rate of cooling of magma.

• Slow cooling rate leads to the formation of coarse-grained rocks and the texture so produced is coarse-grained texture.
• High cooling rate leads to the formation of fine-grained and the texture so produced is fine-grained texture.

Thus the correct answer is option (D).
