How Do Different People View Diverse Living Spaces?

Urban Places Perception of places is dependent on lived experience and understanding of the area. During industrialisation, urban places were perceived as being dangerous and threatening Victorian London, as they were the hotspots of crime, prostitution and...

Six Ways Waves Erode the Coastline

Abrasion- rock and sediment smash and grind against rocks and cliffs, breaking bits off and smoothing surfaces. Hydraulic action- air in cracks in cliffs is compressed when waves crash in. The pressure exerted by the compressed air break off pieces of rock....

Transportation is the Process of Eroded Material Being Moved

The energyprovided by waves, tides and currents transports eroded material. There are four transportational processes: Traction- very big rocks/boulders are rolled along the sea bed by the force of the water. Saltation- pebbles and gravel are bounced along the sea bed...

Deposition is the Process of Dropping Eroded Material

Deposition- when material being transported is dropped on the coast. Marine deposition- when sediment carried by seawater is deposited. Aeolian deposition- when sediment carried by wind is deposited. Happens when the sediment loadexceeds the ability of the water or...

Globalisation

Globalisation is the process by which businesses or other organisations develop international influence or start operating on an international scale. Another definition defines globalisation as the growing economic interdependence of countries worldwide through...

Sub-Aerial Weathering Occurs Along the Coastline

Sub-aerial weatheringthe gradual break down of rock by agents such as ice, salt, plant roots and acids. Weathering weakens cliffs and makes them more vulnerable to   Salt Weathering Caused by saline water. Enters pores/cracks at high tide. Tide goes out, rocks...

How Globalisation Works

Those who make decisions to invest and manufacture overseas, and who help to determine consumer tastes and opinions, come mainly from North America, Europe, and East Asia, as well as oil-rich billionaire investors from Russia, Nigeria, and Saudi Arabia. China, India,...

The Water Cycle and Water Insecurity Definitions

Abstraction: Removal of water from rivers, lakes, canals, reservoirs or from underground strata. Inputs: Ways in which water can get into the system. Store: Ways of storing water in a drainage basin. Output: Ways in which water can leave the system. Flow: Mechanisms...

EQ 1: What is the Geography of Water Supply and Demand?

Know how water supply is controlled by physical factors, within the hydrological cycle. Explain the supply –v- demand balance in specific locations and how this is changing. Explore human degradation of supply by over-abstraction/ saltwater incursion and other forms...

Coasts are Natural Systems

Inputs- sediment; energy from wind, waves, tides and currents. Outputs- sediment can be transported at sea or deposited further down. Flows/transfers- erosion, weathering, transportation and deposition occur. Stores/components- landforms are stores of sediment....

Sources of Energy in Coastal Systems

Wind Created by air moving from areas of high pressure to low pressure. Storms - pressure gradient is high and so strong winds. Generate powerful waves. Waves Created by the wind blowing over the surface of the sea. Friction gives its circular motion. Height is...

Coasts Can Be High Energy or Low Energy

High Energy Coasts Receive high inputs of energy in the form of large, powerful waves. Caused by strong winds, long fetches and steeply shelving offshore zones. Sandy coves and rocky landforms. Erosion is higher than deposition. Low Energy Coasts Receive low inputs of...

Sediment Sources in Coastal Systems

Inputs of Sediment into the System Rivers carry sediment from inland. Sea level rise can flood river valleys, forming estuaries. Eroded material from cliffs by waves, weathering and landslides. Waves, tides and currents can transport sediment into the coastal zone...
