The Greenhouse Effect and Its Impact on Our Planet

The video explains the greenhouse effect, a natural phenomenon essential for life on Earth. It describes how greenhouses work and compares this to the Earth's atmosphere, which contains greenhouse gases like CO2. The increase in these gases, due to human activities such as burning fossil fuels, leads to global warming. The video highlights the consequences of climate change, such as water shortages and rising sea levels, and suggests solutions like recycling and using renewable energy.

What is the primary purpose of the greenhouse effect on Earth?

• To reduce the amount of oxygen in the atmosphere

• To cool down the planet

• To make life possible by maintaining a suitable temperature

• To increase the amount of sunlight reaching the surface

How does a greenhouse maintain optimal conditions for plant growth?

• By circulating cold air

• By using artificial lights

• By allowing sunlight to enter and trapping heat

• By blocking all sunlight
