Sample D will undergo the fastest rate when subjected to chemical weathering.
What is weathering?
It is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
Physical weathering is also known as mechanical weathering. It entails breaking rocks into smaller sized chunks.
Chemical weathering is the decomposition of rocks by chemical action.
From the given choices, option D will have the largest surface area exposed to chemical actions. It has more surface area compared to the others. The more broken a mass is, the more its surface area is.
Reaction rates are affected by:
Increase in surface area
Increase in temperature
Higher concentration
Increase in pressure
The last cube has the highest surface area and will have the fastest rate of weathering.
The world's oceans are rising due to the distribution of water: snow and ice on land, on average, are melting, and that water ultimately ends up in the oceans.
Hearing voices is common in schizophrenia patients. This type of false sensory perception is called an auditory hallucination. A hallucination is a perception of something that is not there or does not exist.
