El efecto invernadero

Greenhouse gases trap heat in Earth's atmosphere, acting like a blanket. Human activities, such as burning fossil fuels and deforestation, increase these gases, leading to climate change. Carbon dioxide and methane are significant contributors, with agriculture emitting a notable portion. Despite clean energy advancements, greenhouse gas levels continue to rise, potentially increasing global temperatures.

What is the primary function of greenhouse gases in Earth's atmosphere?

• To trap heat and keep the Earth warm

• To increase the Earth's rotation speed

• To cool down the Earth's surface

• To block sunlight from reaching the Earth

Which human activity is a major source of carbon dioxide emissions?

• Combustion of fossil fuels

• Using solar panels

• Planting trees

• Recycling waste

How do trees and plants help in reducing carbon dioxide levels?

• By absorbing carbon dioxide and releasing oxygen

• By emitting carbon dioxide

• By blocking sunlight

• By increasing soil erosion

What is a significant source of methane emissions?

• Burning coal

• Livestock farming

• Using electric cars

• Deforestation
