Q. In which place are they most likely to find sand dunes?
WHERE DO WE FIND SAND DUNES? In Michigan, sand dunes are found along much of the shoreline of the Great Lakes. The best known and most studied Michigan sand dune areas are along Lake Michigan. Here, the supply of dry sorted sand and a prevailing wind direction toward land lead to dune development.
Q. Where can you find these otherworldly sand dunes?
Here are a few of the world’s best dunes:

Q. In which type of environment would you be most likely to observe wind erosion?
While wind erosion is most common in deserts and coastal sand dunes and beaches, certain land conditions will cause wind erosion in agricultural areas.
Q. How does each cause erosion?
The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Rainfall – Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams.
Q. What agent of erosion causes the greatest change?
Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil.
Q. What are the negative effects of seawalls?
Seawalls often interfere with natural processes such as habitat migration, causing the reduction of intertidal habitats. However, these effects depend very much on the main wave and sediment transport direction and the design of the seawall.
Q. What are the pros and cons of seawalls?
Sea wall
| Advantages | Disadvantages |
|---|---|
| Protects the base of cliffs, land and buildings against erosion. They can prevent coastal flooding in some areas. | Expensive to build and maintain. Curved sea walls reflect the energy of the waves back to the sea. This means that the waves remain powerful. Can also be unattractive. |
