Answer:
Attractive forces between particles.
Explanation:
Solids keep its shape and volume because of strong attractive forces between the particles.
Other options are incorrect:
Because there is no space between solid particles.
The shape of solid does not depend upon type of particles present.
The shape and volume of solids not depend upon the volume and shape of container.
Properties of solids:
Solids have definite volume and shape.
In solids molecules are tightly pack and very close to each other.
Their melting and boiling point are every high.
The densities of solids are also very high as compared to the liquid and gas.
There are very strong inter molecular forces are present between solid molecules.
Answer: Positive: Coastal areas help prevent erosion; filter pollutants; and provide food, shelter, breeding areas, and nursery grounds for a wide variety of organisms.
Negative: Added to this are impacts such as increased erosion due to coastal development, increased pollution, and increased boat traffic - all of which lead to further habitat loss and put increased pressure on marine species. ...
