Urban renewal is a program of land redevelopment often used to address urban decay in cities.
Explanation:
Urban regeneration happens when an urban area is upgraded. The aim is to improve both the economic and social spaces within a city. This usually takes place when areas of dereliction, pollution or brown-field spaces are restored or the area is used for new purposes.
Glacial ice can transport rocks as big as a house. It has very high transport competence and moves very slowly across a very large distance.
The maximum size of particles that a stream can transport is defined as stream competence. This is a concept under hydrology. Streams depending on its velocity can carry sand, mud, silt and cobble along with the dissolved and suspended load.
The process by which Ocean waves transport sediments, large pebbles and boulders is referred to as Coastal Transportation. During Coastal transportation, large pebbles and boulders are rolled along the seabottom, while beach material is bounced along the seabed.
