The examples of nonmetal all over the world
Some examples of nonmetals found all over the world include:
1. Oxygen - one of the most abundant elements on Earth's surface, making up approximately 21% of the atmosphere.
2. Nitrogen - another abundant element, making up approximately 78% of the atmosphere.
3. Carbon - found in many different forms, such as in graphite and diamonds.
4. Hydrogen - the most abundant element in the universe, making up roughly 75% of all matter.
5. Sulfur - found in many minerals, and is also present in crude oil and natural gas reserves.
6. Chlorine - commonly found in salt deposits, and also in seawater and some types of rocks.
7. Fluorine - a highly reactive element, and the 13th most abundant element in the Earth's crust.
8. Phosphorus - an essential element for life, and is found in many minerals and rocks.

What is the most important material for making cement
The most important material for making cement is limestone. Limestone is the main source of calcium oxide, which is used as a binding agent in the cement-making process. Other materials such as clay, shale, sand, iron ore, and other minor ingredients are also used in the production of cement. However, limestone is the critical ingredient in the production of cement, as it provides the calcium oxide that reacts with water and other materials to form the strong and durable bonds that make cement a reliable building material.
To determine the correct answer, we need to analyze the options provided and their effects on crop growth.
1.) "Boardens the leaves with less yield": This statement seems to describe a negative effect on crop growth, as broader leaves usually indicate reduced productivity. However, it is unclear what exactly causes this effect.
2.) "Causes weed to replace crops": This statement suggests that the application of manure, animal droppings, or fertilizer could lead to increased weed growth, potentially resulting in the displacement of crops. This, therefore, appears to be a negative effect.
3.) "Increases yield and soil fertility": This statement indicates a positive effect, suggesting that the application of manure, animal droppings, or fertilizer can enhance crop yield and improve the fertility of the soil. This is a commonly known benefit of using organic or synthetic fertilizers.
4.) "Reduces over growing of crops": This statement suggests that the application of manure, animal droppings, or fertilizer may help control the excessive growth of crops. It implies a positive effect of these materials.
Considering these options, we can conclude that option 3 is the correct answer: "Increases yield and soil fertility." Applying manure, animal droppings, or fertilizer to crops generally leads to improved productivity and enhances the overall fertility of the soil.
