Answer: Sand Dunes Stabilization
Explanation:
Sand Dunes Stabilization is the process of engaging in actions that keep Sand Dunes in place to protect their Natural Habitat status.
Two such actions can be useful in this scenario.
1. Putting up Vegetation
- The roots of plants can help anchor soil which will reduce the rate at which it is blown around by wind or carried off by water. This will therefore reduce the rate at which sand dunes lose sand.
2. Putting up Wooden Fences
- Putting up Wooden Fences would also help reduce the rate sand dunes end up on roads for the simple reason that it would stop some of them from being blown by the wind and in so doing keep them where they are supposed to be.
True. This is why cliffs change or older buildings are scuffed up. Not because of vandalism or animals it’s because small particles slowly erode away the surface.

Since the components in a mixture are NOT chemically bound, you cannot use chemical methods to separate them lest you’ll counter-intuitively mix them chemically to form compounds. Rather physical methods are used to separate the components.
Explanation:
Air is made of a mixture of gases like Nitrogen, Oxygen and Carbon dioxide and particles like dust particles and water vapor. It is a homogeneous mixture because the components are well mixed up proportionately through out the mixture. The different components air can be separated using their different densities or melting and boiling points.
