1.8 Geological fieldwork

Although much can be learned from samples of rocks in the laboratory or at home, the ‘natural habitat’ of rocks is outdoors. Here the distribution and layout of different rocks is visible wherever rocks are exposed in places such as stream beds, cliffs, rocky shorelines, quarries, or road cuttings. The exposed rocks can be studied in just the same detail as individual laboratory samples, and geological fieldwork allows the size and extent of each rock unit to be seen and the relationships

The issue of climate change draws attention to the power of human activity to transform the planet in its entirety, and it is brought into sharp focus by the predicament of low-lying islands like Tuvalu. As we have seen in this unit, the issue of rising sea level and other potential impacts of changing global climate also point to the transformations in the physical world that occur even without human influence.

1.1.2 A balancing act: conservation and sustainable development

All around this coast are examples of efortsf to protect or enhance the environment. There are nature reserves, country parks and protected habitats, and the whole coastal fringe is designated as an area of scientific interest requiring special protection. There is also evidence of the need to manage the environment to ensure, so far as possible, compatibility between competing interests.
