In the past century, the world has recorded a rapid increase and decrease in population in different geographical areas. This has been influenced by different factors such as urbanization and family planning.
Urbanization creates better employment opportunities and wages. It also provides better social amenities such as schools and hospitals. These encourage people to move from rural areas to urban areas in search of a better living. The migration results in a decrease of population is the rural areas and a rapid increase in population in the urban cities.
Increased access to contraceptives has enabled women to limit family sizes. Women are able to plan for the number of children they intend to have. This has generally decreased the population growth in developed regions.
Answer:
Deposition occurs when the sea has less energy, eg in sheltered bays . Material that has been eroded from the coast is transported by the sea and later put down. Longshore drift is a process of transportation that shifts eroded material along the coastline. Swash carries sediment up the beach at an angle.

Answer and explanation:
a) The plate tectonics is a theory that suggests that Earth's outer shell is divided into several plates that glide over the mantle (rocky inner layer above the core), there are seven major plates that make up 94% of the Earth's surface and many smaller plates making up the other 6% (I annexed a map of those tectonic plates). The tectonic plates are in motion (presumably since the beginning of time), the movement of the plates creates three types of tectonic boundaries:<em> convergent </em>(plates move into one another); <em>divergent </em>(plates move apart); and <em>transform</em> (plates move sideways in relation to each other).
b)The Mid-Atlantic Ridge (MAR) is a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean. <em>The MAR developed as a consequence of the divergent motion between the Eurasian and North American, and African and South American Plates</em>
c) In areas where the plates come together, sometimes volcanoes will form, they can also form in the middle of a plate, in places called "hot spots" where magma rises upward until it erupts on the seafloor. The Hawaiian Islands<em> were formed by such a hot spot occurring in the middle of the Pacific Plate.</em>
