think about it

After the rice is harvested, a green manure crop is planted on the cultivated land. The following spring, plow the green manure into the fields. This not only increases the source of fertilizer and restores the fertility of the rice fields, but also plays a great role in improving the soil.

Natural resources are divided into renewable resources and non-renewable resources.

Land, sunlight, forests, water and water energy, etc., can be renewed, regenerated, or recycled in a short period of time, and are called renewable resources.

Coal, petroleum, iron ore, etc. are formed and regenerated in a very slow process. Compared to human history, they are almost non-renewable. They are called non-renewable resources.

Plant remains in the bog are transformed into mud, and the peat is buried underground over time, eventually turning into coal. This process takes millions or even tens of millions of years.

Recognize and differentiate between renewable and non-renewable resources

1. Distinguish which of the following natural resources are renewable resources and which are non-renewable resources, and give the reasons.

Hot spring trees grassland tidal energy Tibetan antelope

Wind energy Marine fish Nuclear energy Natural gas Granite

2. Based on the graphic information on page 64 of the textbook, discuss and think: Are renewable resources “inexhaustible”?

With population growth and economic development, humankind's demand for natural resources is increasing. For renewable resources, if they are utilized rationally and attention is paid to protection and cultivation, sustainable utilization can be achieved.

Non-renewable resources should be cherished and used sparingly!

Discussion: Do you think people have some understandings and practices in the process of utilizing natural resources? Are they correct?

Water is a renewable resource, so it can be used as you wish.

Mineral resources reserves in the world and in our country are abundant and can be used with confidence.

Metal Ore is non-renewable, so don't use it yet.

With the development of science and technology, the efficiency of resource utilization will be improved and new resources will be developed.
