Match the following. Match the items in the left column to the items in the right column.

1. biomass
able to be recycled or replenished in a short period of time
2. hydropower
engine with large blades
3. renewable
use of water to generate electricity
4. turbine
organic material made from plants and animals

Explanation:

Turbine:

Engine with large blades.

Explanation:

It is the rotatory device which use fluid action to perform its function. It consist of circular blades. The moving fluid hits on the blades in turn blades produces rotational energy to the rotor which helps to create electricity.

Renewable:

Able to be recycled or replenished in a short period of time.

Explanation:

Renewable materials are used and can be generated again to be used again. These are materials which can be recycled again.

Example:

biomass.

Biomass.

Organic material made from plants and animals.

Explanation:

Biomass materials are made up of plants or animals. They have stored chemical energy. They are used to generate the electricity. When bomass are burned they produces heat.

Some common examples includes,

Agricultural crops = also converted as liquid biofuels.

Food waste = burned to generate the energy which is also used in power plants.

wood = burned to produces energy.

Hydropower.

Use of water to generate electricity.

Explanation:

In hydropower plants energy from flowing water is converted into electricity. The whole system consist of three main parts.

Power plant = which convert the energy into electricity.

A reservoir : Which store the water.

Dam = which control the flow of water.
