As geologists‚ we examine layers of sediment on the Earth’s surface to approximate the dates of past geologic time periods. Ah sediment as you know is material like sand‚ gravel‚ fossil fragments that is transported by natural processes like wind ‚ water flow or the movement of glaciers. So sediment is transported and then deposited and it forms layers on the Earth’s surface over time. We examine these layers to learn about different geologic time periods including when they began and ended. For

rural and urban areas (15 marks) Rural and urban areas in Northern Ireland have been impacted in different ways by population change and migration. Contrasts are evident between the area of rural settlement known as ‘Mourne Country’ (including the village of Hilltown) and the area of rural-urban fringe known as ‘Mid-Down’ (including the village of Hillsborough). The contrasts are interesting because population and service provision are falling in remote rural areas but growing in areas of rural-urban
