Question

Which of the following examples of weathering are in the correct sequence?

Ice wedging: water freezes and expands in rocks → water seeps into cracks of rocks → rocks break apart


Chemical weathering: water containing acid seeps into a sedimentary rock → sedimentary rock reacts with the acid → sedimentary rock dissolves


Mechanical weathering: roots grow and expand inside the cracks of rocks → growing roots cause pressure to break down rocks → roots find cracks in rocks


Cavern: temperature changes weaken the structure of rocks → at night rocks cool down and during the day rocks heat up → rocks start to flake or peel like an onion over time

Answer 1

the chemical weathering one

Answer 2

b

Step-by-step explanation:

acid seeps into a sedimentary rock → sedimentary rock reacts with the acid → sedimentary rock dissolves
