Q & A

What are renewable natural resources?

Renewable natural resources are resources that can replenish themselves naturally or have an unlimited quantity, allowing for continuous use.

What is solar energy, and why is it considered renewable?

Solar energy comes from sunlight, which is abundant and inexhaustible, making it a renewable energy source. It can be used for heating, electricity generation, and other applications.

How is wind energy harnessed, and what are its benefits?

Wind energy is harnessed through wind turbines that convert moving air into electricity. It is considered a cheap and environmentally friendly alternative energy source.

Why is water considered a critical renewable resource?

Water is essential for life and is abundant in many regions, especially in places like Indonesia, where it is used for hydroelectric power generation and irrigation.

What role do plants play in renewable resources?

Plants are living organisms that can reproduce and grow, making them renewable resources. They provide food, oxygen, and materials for various human needs.

How do terrestrial animals contribute to renewable resources?

Terrestrial animals provide protein for human diets and can assist in agriculture and transportation. They are also renewable because they can reproduce.

What is biomass, and how is it utilized?

Biomass refers to organic materials, such as plant and animal waste, that can be reused for energy production, composting, and manufacturing.

What is geothermal energy, and what are its advantages?

Geothermal energy is derived from the Earth's heat and is considered a clean and sustainable energy source for electricity generation and heating.

How does tidal energy work?

Tidal energy is generated from the rise and fall of sea levels due to gravitational forces, and it can be harnessed to produce electricity, although it is less commonly utilized.

What is the importance of responsible resource management?

Responsible management of renewable resources is crucial to prevent depletion and maintain ecological balance, ensuring that these resources remain available for future generations.
