The Greenhouse Effect and Climate Change: Understanding Our Planet's Rising Temperatures

The video explains how climate change is causing rising temperatures, sea levels, and melting ice. It introduces the greenhouse effect, which naturally warms the Earth, making it habitable. However, human activities, such as pollution and greenhouse gas emissions, are intensifying this effect, leading to global warming.

What are some of the observable effects of climate change mentioned in the video?

• Decreasing global temperatures

• Rising sea levels

• Increasing ice at the poles

• Decreasing greenhouse gases

What is the primary function of a greenhouse?

• To provide warmth for plants

• To increase humidity

• To block sunlight

• To cool down the environment

How does sunlight affect the temperature inside a greenhouse?

• It is absorbed and reflected, raising the temperature

• It escapes without affecting the temperature

• It is completely absorbed by the glass

• It cools down the greenhouse

What would Earth's average temperature be without the natural greenhouse effect?

• 25 degrees Celsius

• Minus 18 degrees Celsius

• 0 degrees Celsius

• 15 degrees Celsius

How does Earth's atmosphere contribute to the greenhouse effect?

• By absorbing and reflecting sunlight

• By blocking all sunlight

• By cooling down the planet

• By allowing all heat to escape

Which gases are primarily responsible for enhancing the greenhouse effect due to human activities?

• Argon and krypton

• Carbon dioxide, methane, and nitrous oxide

• Oxygen and nitrogen

• Helium and neon

What is the result of increased greenhouse gases in the atmosphere?

• Decreased global temperatures

• Stabilized climate conditions

• Enhanced greenhouse effect and global warming

• Increased heat escaping into space

What analogy is used to describe the effect of increased greenhouse gases?

• A greenhouse with no glass

• A greenhouse with thick glass

• A greenhouse with thin glass

• A greenhouse with broken glass
