Rebekka notices a huge crack in a large boulder in her garden she realizes the crack was caused by frost wedging place the steps of the frost wedging process in order
a. the freeze-thaw cycle continues to deepen the crack until the rock splits into 2 pieces
b. rain water is stored in rock and seeps into a hairline crack during a rainfall
c. because ice occupies more space than water, the ice wedges the crack open
d. rainwater in the rock crack freezes into ice
e. the temperature falls below 0° celsius

The correct order is:

B. Rain water is stored in rock and seeps into a hairline crack during a rainfall;

E. The temperature falls below 0° Celsius;

D. Rainwater in the rock crack freezes into ice;

C. Because ice occupies more space than water, the ice wedges the crack open:

A. The freeze-thaw cycle continues to deepen the crack until the rock splits into 2 pieces;

The water from the rain gradually manages to weather parts of the rock. As it does, small cracks appear in it. Once there's cracks, the water from the rainfall also starts to store inside the rock. When the colder period of the year comes, and the temperatures fall bellow 0°C, the stored water freezes. The ice starts to spread inside the crack, thus creating pressure inside the rock. As the pressure is becoming bigger and bigger, the rock will eventually crack into two or more pieces.
