Question

q2. how many years can carbon stay in the form of coal in the environment?
q3. how does human activities create pollutants?
q4. what is the other name of water cycle called as?
q5. where does the energy that propels the water cycle come from?
q6. what is the energy that distributes the water vapors around the world?
q7. which system is supported by condensing of water vapor on land?
q8. how does water circulate through living organisms?
q9. what are the channels of water that reach oceans called as?
q10. what is responsible for which processes in a living cell?

Explanation:

Q2: Coal - formed over millions of years, carbon can remain for very long periods, often millions of years.
Q3: Human activities like burning fossil fuels release pollutants into air, water, and soil. Industrial processes also produce waste products that are pollutants.
Q4: The water cycle is also known as the hydrologic cycle.
Q5: The energy that propels the water cycle comes from the sun. Solar energy causes evaporation of water from oceans, lakes, etc.
Q6: Wind energy distributes water vapors around the world. Wind moves the moist air masses.
Q7: The terrestrial ecosystem is supported by the condensing of water vapor on land as it provides water for plants, animals, etc.
Q8: Water circulates through living organisms via processes like ingestion, transpiration (in plants), and excretion.
Q9: The channels of water that reach oceans are called rivers and streams.
Q10: The question is too general. However, various components like enzymes, water, and nutrients are responsible for different processes in a living cell such as metabolism, growth, and reproduction.

Answer:

Q2: Millions of years
Q3: Burning fossil fuels, industrial processes etc. release waste products as pollutants
Q4: Hydrologic cycle
Q5: The sun
Q6: Wind energy
Q7: Terrestrial ecosystem
Q8: Ingestion, transpiration (in plants), excretion etc.
Q9: Rivers and streams
Q10: Enzymes, water, nutrients etc. for processes like metabolism, growth, reproduction
