A rock containing iron becomes soft and crumbly and reddish-brown in color.  It probably has been chemically weathered by -

• abrasion
• carbon dioxide
• oxygen
• acid rain

A hot wet climate causes weathering to take place -

• slowly
• rapidly
• unevenly
• at the same rate as when the climate is dry and cool
