Answer:
1. Native flora/plants. This is because native plants are best suited to live in the type of environment that they exist in, and its roots are used to stabilise soil erosion from water
2. Use terracing in farming, as the long slope is shorted into smaller groups of shot flatter slopes, reducing soil erosion
3. Planting cover crops, which are crops that grow horizontally, which form essentially a large cover over the soil, which prevents wind from blowing soil away
4. Strategically placed rocks or boulders can change the way water flows, which reduces the amount of soil erosion as it diverts the water to another direction.
A common crescent-shaped dune with horns pointed downwind is called a barchan dune.
A barchan or barkhan dune is a crescent-shaped dune. Barchan ("BAR-kahn") dunes form in areas with only one wind direction, and little or no vegetation. If conditions were "perfect"—the landscape was flat, winds blew from only one direction, vegetation could not grow, and sand was available but limited —barchan dunes would dominate a sandscape. One of the commonest types of dunes, it occurs in sandy deserts all over the world. Barchans are mostly formed by the wind from one direction and appear convex. They are arc-shaped, significantly asymmetrical in cross-section, with a gradual slope towards the wind sand ridge, and made out of well-sorted sand.

Metallic minerals become concentrated in liquid magma due to igneous, hydrothermal processes.
When magma forms first, it cools down and sink. The minerals concentrate at the top forming hydrothermal fluid.
Answer:
Image result for Reposition the hazardous items to reduce the impact of disaster.
Awareness, education, preparedness, and prediction and warning systems can reduce the disruptive impacts of a natural disaster on communities. Mitigation measures such as adoption of zoning, land-use practices, and building codes are needed, however, to prevent or reduce actual damage from hazards.
