What type of weathering is shown in the picture? a) Mechanical; b) Biological; c) Chemical; d) Magical
b) Biological (plant roots can enter a small crack in a rock. As the root grows larger the crack gets larger. This weakens the structure of the rock).

What happened to this rock?
This boulder was split by gelifraction (water freezes and expands, working to wedge the rock open). This is a type of mechanical or physical weathering.

Chemical weathering is most likely to take place in environments that are: a) cold; b) wet; c) dry.
b) wet (These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best.))
