Answer: Mining and quarrying can be very destructive to the environment. They have a direct impact on the countryside by leaving pits and heaps of waste material. The extraction processes can also contaminate air and water with sulfur dioxide and other pollutants, putting wildlife and local populations at risk.
Answer:
Exposure latitude is the extent to which a light-sensitive material can be overexposed or underexposed and still achieve an acceptable result. This measure is used for digital and analogue processes, e.g. optical micro lithography or photography.
Explanation:
A glacial valley cross-sectional shape is a U shape whereas a stream valley is usually a V shape. The U shape comes from the scouring action of the alpine glaciers which carries rocks with it which can abrade the walls of the valley and the glacier occupies the whole valley so scours out such a shape whereas the stream cuts down and water washes in from the sides of the valley into the stream or river creating the V shape.
Answer: The earth layers and atmospheric layers are distinctly different.
Explanation:
The earth layers are made up of solid matter whereas the atmospheric layers are made up of gases.
The earth layers provide the base for the survival of diversity of living beings whereas the atmospheric layers only allow microbes which can survive in extreme temperature conditions.
The stratospheric layer of the atmosphere protects the living beings from the harmful radiations striking on the surface of earth and they are capable of causing mutation whereas the lithosphere or any other surface layer of the earth also absorb thermal energy from sun but does not provide protection against harmful affects of ultraviolet radiations.
Answer:
There are four main types of species interactions that occur between organisms in an ecosystem: Predation, parasitism and herbivory - In these interactions, one organism benefits while the other is negatively affected. * Competition - Both organisms are negatively affected in some way due to their interactions.
