Natural Resources

1. A NATURAL RESOURCE IS A SOURCE OF PRODUCTS THAT ARE INHERENT TO EARTH

2. NATURAL RESOURCES INCLUDE RENEWABLE AND NON-RENEWABLE RESOURCES

3. NATURAL RESOURCES ARE EXPLOITED TO CREATE THE PRODUCTS AND SERVICES THAT WE DEPEND ON

4. NATURAL RESOURCE EXTRACTION CAUSES GREAT ENVIRONMENTAL DISRUPTION

What is a natural resource?

There are Two types of Resources -

1RENEWABLE 2NON RENEWABLE

RENEWABLE SOURCES

Wind Solar Energy Forest

WIND

• Wind is caused by the uneven heating of the atmosphere. Some areas of the world, such as costal regions, have more wind than others because the terrain of the area is relatively flat and has few obstacles to block the wind from blowing.

• The power of the wind drives sailboats. It has been used to power windmills that grind grain. Windmills can also use the circular movement of the blades to turn a turbine. This is increasingly used as a means of generating electricity.

SOLAR ENERGY

• The sun is the closest star to Earth. It brings heat and light to the world. Some areas of the world, such as those closest to the equator, have more sun than others.

• The sun shines naturally but it is not affected by human activity. It cannot be used up. However, its intensity varies with the seasons, and it is not available at night.

Non-Renewable Resources

• Fossil Fuels 1.Coal 2.Petroleum 3.Natural Gas

• Fossil fuels take millions of years to form. They are the product of the fossilized remains of dead plants and animals that have been exposed to the heat and pressure deep within the earth’s crust. There are many types of fossil fuels, such as petroleum (gasoline), natural gas, and coal.

FOREST

• Forests have moderate climate, help cleanse the air and water, and house wildlife. They also provide thousands of wood products and related jobs.

• Trees are used to make paper, hockey sticks, flooring and food

• Forests face threats from fire, pollution, erosion and acid rain

• Fossil fuels are arguably one of the most valuable natural resources in modern times. It is estimated that 86 percent of the world’s energy comes directly from burning fossil fuels. Fossil fuels are the source of energy for almost every machine, including the generators that produce electric energy.

• Because fossil fuels take so long to form, they are being consumed faster than they can be produced. Fossil fuels are a major contributor to air pollution because when they are burned they release many dangerous gases such as nitrogen dioxide, methane, and carbon dioxide.
