List down 3 ways on how you can protect the estuaries and intertidal zones so that interaction of the and abiotic factor in these areas will not be disturbed.

Intertidal zones are regions which lie above the water level which receives low tides. Estuaries are the closed bodies of coastal waters which contain brackish water.

Explanation:

The ways through which the intertidal zones and estuaries can be protected are as follows:

1. The chemical discharge from factories and sewage discharge must be restricted or prohibited in these areas so that the water and air quality remains good necessary for the survival of living beings.

2. Prohibiting the waterways to prevent the discharge of oils which can contaminate water of estuaries and soil of intertidal zones.

3. The trash of polythene bags, plastic materials, vegetable matter discharged from the city must be cleaned up to retain the quality of soil and water.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
