Answer:

D

Explanation:

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.

How much energy does an autotroph derive
prohojiy [21]

Answer:

Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Food is chemical energy stored in organic molecules. Food provides both the energy to do work and the carbon to build bodies. Because most autotrophs transform sunlight to make food, we call the process they use photosynthesis.
