You can compare the student's answer with the example to determine if it is the same standard, better or worse than the example. A beach is composed of fine sand particles rather than shingle, pebbles or rocks. Many of the new technologies that we develop enable us to support larger populations, thereby increasing the carrying capacity. Positive feedback is less common. The rabbits could exceed the carrying capacity one year, but then there wouldnt be enough carrots the following year. Atmospheric climate, weather and climate change Landforms of erosion cracks, caves, stacks, stumps, wave-cut platforms, blowholes The Holderness Coastline is one of Europe's fastest eroding at an average annual rate of around 2 metres per year.

Negative feedback Your proactive approach is a rare but extraordinary quality that strengthens our team. Major coastal events such as those to be discussed in the next module (Module 5), although destructive, provide significant opportunities to further consider how these coastal systems continue to respond and evolve in the face of short-term and long-term processes.
