The Greenhouse Effect and Its Impact on Earth's Climate

The video explains the greenhouse effect, which keeps Earth warm by trapping heat with gases in the atmosphere. It compares this to how a greenhouse works. Human activities, like burning fossil fuels, increase greenhouse gases, affecting Earth's climate. NASA monitors these gases to understand their impact.

What makes Earth a suitable place for living organisms?

• Its distance from the Sun

• Its size and mass

• The greenhouse effect

• The presence of water

How does a greenhouse maintain warmth?

• By using insulation materials

• By reflecting sunlight

• By trapping sunlight and heat

• By using electric heaters

What are greenhouse gases?

• Gases that trap heat in the atmosphere

• Gases that are harmful to plants

• Gases that cool the Earth

• Gases that are only found in greenhouses

Which of the following is NOT a greenhouse gas?

• Carbon dioxide

• Water vapor

• Methane

• Oxygen

How do human activities affect the greenhouse effect?

• By increasing the amount of greenhouse gases

• By reducing the amount of sunlight reaching Earth

• By decreasing Earth's temperature

• By making the atmosphere thinner

What is one consequence of increased greenhouse gases?

• A warmer Earth

• More frequent earthquakes

• Increased volcanic activity

• A cooler Earth

What do NASA satellites measure in the atmosphere?

• The amount of sunlight

• The speed of wind currents

• The thickness of the atmosphere

• The levels of greenhouse gases

Why is it important to monitor greenhouse gases?

• To track animal migration

• To measure Earth's rotation speed

• To understand their impact on climate

• To predict weather patterns

What can the data from NASA satellites help scientists determine?

• The origin of greenhouse gases

• The height of mountains

• The age of the Earth

• The depth of the oceans
