Answer:
The correct answer is erosion

- Mechanical weathering is the process of breaking of big rocks into tiny or smaller pieces. It is basically a process of conversion of big rocks into sediments thus leading to the formation of soil.
- Chemical Weathering is the process of breaking down of big rocks into tiny pieces by chemical reactions instead of mechanical processes.
- Erosion is the process of removal of soil, sediments and dissolved substance from one location and transporting it to another location on earth crust.
- Metamorphism is the process of change in the structure or com[position of a rock by the action of pressure, temperature or other natural forces.

Answer:
2.62 years
Explanation:
The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.
If a radioactive material is cut into pieces, each piece has the same half life as the whole material.
Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.
