Step 1
Formation of a Sand Dune
Answer
Sand dunes are formed through the process of wind erosion and deposition. When wind blows over loose sand, it carries particles and deposits them when the wind speed decreases, typically around natural obstacles, forming a dune. Diagrams should illustrate the wind direction and the shape of the dune, showcasing the slip face and windward side.
Step 2
Formation of a Fjord
Answer
Fjords are created through glacial erosion. During the last Ice Age, glaciers carved out deep valleys as they moved through coastal regions. Upon retreat, these valleys flooded with seawater, forming fjords. Diagrams should represent the U-shaped valley and the freshwater mixing with seawater, emphasizing the steep cliffs characteristic of fjords.
