EVERYDAY SCIENCE

Detailed explanation-1: -Carbon dioxide (CO2) is a greenhouse gas. This means that it causes an effect like the glass in a greenhouse, trapping heat and warming up the inside. This effect is important: without the CO2 that naturally exists in the atmosphere, Earth might be too cold to support human life.

Detailed explanation-2: -Carbon dioxide is Earth’s most important greenhouse gas: a gas that absorbs and radiates heat. Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb heat radiating from the Earth’s surface and re-release it in all directions-including back toward Earth’s surface.

Detailed explanation-3: -Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. During the day, the Sun shines through the atmosphere.

Detailed explanation-4: -Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years.

Detailed explanation-5: -The greenhouse effect is the way in which heat is trapped close to Earth’s surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.
