Can someone give an introduction for natural resources ? The introduction must:
o Hook the audience or reader
o Introduce the topic or main idea
o Introduce the supporting details

The environment consists of artificial and natural components. The natural components of the environment like air, water, land, soil, plants and animals are called natural resources. These resources are taken as gift of nature to human beings. Mankind used these natural resources for their prosperity and survival. Some resources like air, water, land, plants and animals can be regenerated by natural process but mineral resources cannot be regenerated, it has its own importance. A continuous and dynamic cyclic of natural resources is found in nature.

Classification of natural resources

People get different things from the natural environment. Some natural resources available in natural environment can easily and directly used. For example solar energy, water, fruits from plants can be directly used without any processing but some of the natural resources cannot be used, they need to be processed and refined, e.g. solar energy, water tides, winds, flowing water. We obtain heat and light energy from the sun as a principal source of energy in the earth. We use flowing water to rotate dynamo and generate electricity. All these resources do not exhaust due to their use. So, they are called perpetual resources.

Renewable resources

The natural resources that can be replenished through natural formation even after their utilization are called renewable natural resources. E.g. grass, food, plants, raw materials, etc. They die and get replaced by new vegetation. Soil formation is continuous and slow and other soil gets replaced by new soil. Water, wildlife, animals, plants, etc. are said to be renewable resources and but over exploitation of resources gets plants and animals lead to extinction.

Non renewable resources

The resources that are in fixed quantity in the nature and cannot be obtained by any natural means are non - renewable natural resources. e.g. oil, coal, diesel, petroleum, etc are in fixed amount in the earth. They cannot be regenerated once they are finished. Such natural resources should be used properly and wisely and should preserve for future.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
