Many mineral’s elements essential for plants. Released when rocks weather (soil formation ->available for plants

Question 9

Crystaline

Answer 9

Regular arrangement of atoms

Question 10

Amorphous

Answer 10

Atoms do not have a regular order. When atoms do not have enough time to fully organise themselves. (fast solidification)
