How do sandhills form?
Sandhills form when wind blows loose sand into dunes, which can be stabilized by vegetation. The process is influenced by wind patterns, availability of sand, and the presence of vegetation to hold the sand in place. Over time, sandhills can grow and shift due to changing wind patterns.

Why buckets containing sand are kept ready at petrol bunks?

Why is fire put off if sand is poured on it?
Pouring sand on a fire helps extinguish it by smothering the flames and cutting off the fire's oxygen supply. Fire requires three elements to burn: heat, fuel, and oxygen, known as the fire triangle. The sand creates a barrier that prevents oxygen from reaching the flames while also absorbing heat, effectively cooling the fire and stopping combustion. Additionally, the weight of the sand can help to physically suppress the flames.
Why should sand be poured to put out fire?
Sand can smother a fire by cutting off its oxygen supply, which is necessary for combustion. By pouring sand on a fire, it helps to reduce the flames and cool down the burning material, eventually extinguishing the fire. Sand is often used as a fire extinguishing agent for certain types of fires, such as chemical or metal fires, where water may be ineffective or even dangerous.

Why are fire pails rounded on the bottom?
Fire pails are rounded on the bottom to enhance stability and minimize the risk of tipping over. This design allows them to better withstand movement and can help in preventing spillage of contents, such as water or sand, which are used for extinguishing fires. Additionally, the rounded shape facilitates better handling and pouring of materials in emergency situations.
