3. Name the places in Australia that have large
deposits of gold
4. Name two places from where petroleum is drilled
5. What is the disadvantage of solar power
6. What is biogas?​

Answer 1

Answer:

1.There are four main mining methods: underground, open surface (pit), placer, and in-situ mining.

Underground mines are more expensive and are often used to reach deeper deposits.

Surface mines are typically used for more shallow and less valuable deposits.

Oilfields in North-East India:

The Digboi field: ADVERTISEMENTS: ...

The Naharkatiya field: ...

The Moran-Hugrijan field: human.5.High initial costs for material and installation and long ROI (however, with the reduction in cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank.6.Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen, primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.

• Jundee.
• Telfer.
• Cowal.
• Sunrise Dam.

4.    (i) Ankaleshwar and Kalol

(ii) Digboi and Moran.    

5.   High initial costs for material and installation and long ROI (however, with the reduction in cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank.

6.  a mixture of methane and carbon dioxide produced by the decomposition of plant and animal waste, that is used as fuel is known as biogas.
