Answer:
The process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Weathering breaks down and loosens the surface minerals of rock. Hence, the broken rocks are transported to another place where it decomposes and forms soil. Therefore weathering is important for soil formation
Southwards parallel to the shoreline.
A geological course that is made up of the movement of sediments like silt, clay, shingle and sandd within a coast parallel to the shoreline, which is reliant on oblique approaching wind direction is called longshore drift. Oblique incoming wind restraints water along the coast, and so creates a water current which moves parallel to the coast.
Sound intensity is the intensity/volume of sound. Frequency is how high or low the sound is.
