• When the plant moves water from the roots to the leaves, the rock breaks.

Weathering is the process of -

• Moving sediment from one place to another

• Dropping or leaving sediment in a location

• Breaking down rocks into sediment

An example of chemical weathering is -

• Ice wedging

• Oxidation

• Animals burrowing

• Crashing waves

An example of physical weathering is -

• Plant roots and leaves releasing acids

• Carbonic acid dissolving limestone

• Large temperature changes

• Lichens growing on rocks
