Match each activity to its consequence,
Use of extinguishers
Combustion of fossil fuels
Use of carbon
tetrachloride as an
industrial solvent
Agricultural activities
Use of aerosol sprays
containing CFCS
Increase in greenhouse gases
Ozone depletion

1) Use of aerosol sprays containing CFCSIncrease in greenhouse gases and causes Ozone depletion.

2) Use of extinguishers in the Combustion of fossil fuels.

3) Use of carbon tetrachloride as an

industrial solventAgricultural activities

Explanation:

Aerosol sprays containing CFCS which is a harmful substance causes depletion of ozone layer which protects us from harmful radiation of the sun.

Carbon tetrachloride is used in agriculture activities such as a fumigant in the storage house for preventing the grains from pest attack.

Extinguishers are used for controlling the Combustion of fossil fuels.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
