a. mountains
b. soil
c. ice cracks
d. glaciers
Soil results from the breakout of rocks and the mixing of resulting particles with organic matter and water. So, the correct option is (B).
Soil is produced from rocks which are the parent material through the processes of weathering and natural erosion. Water, wind, temperature changes, gravity, chemical interactions, living organisms and pressure differences all help break down the parent material.
The four basic processes which occur in soils are
1. Additions
2. Losses
3. Transformations
4. Translocation
The organic part of soil is formed when plants and animals die and then their bodies decompose, or break down, and mix with rock particles. Organic matter which is called humus helps to create pores in the soil. It keeps the soil soft and loose.
Thus, soil results from the breakout of rocks and the mixing of resulting particles with organic matter and water. So, the correct option is (B).

Explanation:
Difference between a runner spitting versus just someone standing still
Explanation:
Runners while running do breathe, pant, and heave heavily which leads to spitting in the open as a habitual practice. This spitting while on motion leads to heavy dispersal of aerosol droplets which suspends in the air.
Droplets due to respiratory or spitting sources from any person who is infected with any infectious and contagious viral, bacterial, or other infectious diseases will have high chances of the pathogen present in them.
Further the rate and spread of droplet dispersal and transmission of pathogen will be higher compared to that from someone standing still. This puts greater potential for the spread of such droplet transmitted diseases.
Hence proper distancing should be maintained between runners and others to prevent spread of droplet transmitted diseases.
