Answers
Answer:
Natural resources are materials from the Earth that are used to support life and meet people's needs. Any natural substance that humans use can be considered a natural resource. Oil, coal, natural gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil and water.
Explanation:
When placed carefully, the plate would float in water. However, the spoon immediately sinks. Why do some things float while some others sink? This mainly happens because of a phenomena known as buoyancy.
Everything displaces water equal to its volume. If the displaced water is more than the weight of a particular thing, then that object floats. On the other hand, when the displaced water is less than the weight of an object, it sinks. Sounds interesting, isn’t it? Now, we will look at some common examples in our daily life.
