Jurassic Coast
Definition
The Jurassic Coast is a UNESCO World Heritage Site in southern England. It is 155 miles (249 km) long and stretches from Lyme Regis in Dorset to East Devon. The coast is famous for its fossils, which date from the Jurassic period, which lasted from 201.3 million to 145.5 million years ago.
The Jurassic Coast is home to a variety of fossils, including dinosaurs, crocodiles, fish, and plants. The fossils are found on the cliffs and in the rocks on the beach. The cliffs are constantly eroding, which exposes new fossils.
The Jurassic Coast is a popular tourist destination. Visitors can go fossil hunting, hiking, and kayaking. There are also a number of museums and visitor centres along the coast.
The Jurassic Coast is a valuable resource for scientists. The fossils help us to understand the evolution of life on Earth. The coast is also a reminder of the Earth's long and complex history.

AQA Science Exam Question and Answer
Question:
Explain the geological significance of the Jurassic Coast and its role in providing insights into Earth's history. Describe the key features and formations that make this coastline a UNESCO World Heritage Site. (8 marks).
Answer:
The Jurassic Coast is a UNESCO World Heritage Site located along the southern coast of England. It holds immense geological significance, providing a unique window into Earth's history and the processes that have shaped its landscape over millions of years.
This coastline spans approximately 185 million years of Earth's history, primarily from the Triassic to the Cretaceous periods. The diverse rock formations and fossils found here offer a chronological record of ancient environments, ecosystems, and evolutionary changes. The presence of fossils, including ammonites and ichthyosaurs, helps scientists reconstruct past marine life and understand how species adapted to changing conditions.
Key features of the Jurassic Coast include dramatic cliffs, rocky beaches, and stunning natural arches. Notably, the layered rock formations, such as the iconic limestone stacks of Durdle Door, showcase the passage of time through the different sedimentary layers.
The Jurassic Coast's formations have been shaped by various geological processes like erosion, deposition, and tectonic activity. Studying these processes allows scientists to unravel the history of Earth's landforms and ecosystems.
In conclusion, the Jurassic Coast is a living textbook of Earth's geological history. Its diverse formations and fossils provide invaluable insights into past climates, species evolution, and geological events, making it a remarkable educational and scientific resource.
