Describe a solution to traffic congestion in urban areas.
Traffic congestion pricing, as practised by the Singapore government, may be a solution to heavy congestion in urban areas. Under this scheme, vehicle drivers are charged an amount of money based on the time which they enter the Central Business District. The amount charged on drivers will be higher during peak hours as opposed to off-peak hours, while free entry is granted to all drivers during late night hours between 10 pm and 7 am, as well as on weekends.

Describe the process of hydraulic action.
Hydraulic action is an erosional process that takes place on the coast. In this process, water enters cracks on the cliff face called joints. As the water enters the cracks, it forces air into it building up air pressure. The pressure that the air puts on the cracks widens it over time, and eventually causes the rock on the cliff face to break.

Why is the population growth rate of Less Economically Developed Countries (LEDC's) generally higher than More Economically Developed Countries (MEDC's)?
The population growth rate of Less Economically Developed Countries (LEDC's) are generally higher than More Economically Developed Countries (MEDC's) due to several political, social and economical factors. Economically, LEDC citizens are mostly poor and are involved in agricultural jobs such as farming. As these agricultural jobs do not offer a fixed pay and are labour intensive, parents often give birth to a high number of children with the hope that the children will seek work in the city and support them when they are at an older age. On the other hand, MEDC citizens are mostly focused on progressing their career, hence most MEDC women would prefer to get a higher qualification or job position, which delays their marriage and child birth.
