What the greenhouse effect is and how it affects the Earth's temperature?
Understanding the Greenhouse Effect
The greenhouse effect is a natural phenomenon where greenhouse gases in the Earth's atmosphere trap infrared radiation from the Sun, keeping the Earth's surface warmer than it would be otherwise. An increase in these gases leads to a stronger effect and global warming.
Final answer:
The greenhouse effect is a natural phenomenon where greenhouse gases in the Earth's atmosphere trap infrared radiation from the Sun, keeping the Earth's surface warmer than it would be otherwise. An increase in these gases leads to a stronger effect and global warming.

The Greenhouse Effect Explained
The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth, it is absorbed by the surface and then re-radiated in the form of infrared heat. The Earth’s atmosphere, which contains greenhouse gases like carbon dioxide, is largely transparent to the incoming sunlight but absorbs this re-radiated infrared radiation. These gases then trap the heat, preventing it from escaping into space, much like the glass of a greenhouse. This process keeps our planet warm enough to sustain life.
An increase in the concentration of greenhouse gases leads to a stronger greenhouse effect and a warmer Earth surface. This is largely due to human activities, such as burning fossil fuels and deforestation, which release additional greenhouse gases into the atmosphere. As a result, the average temperature of the Earth is rising, a phenomenon known as global warming, which is a significant aspect of broader climate change.
What are some human activities that contribute to the increase in greenhouse gases? Some human activities that contribute to the increase in greenhouse gases include burning fossil fuels for energy, deforestation, industrial processes, agriculture, and transportation. These activities release carbon dioxide, methane, and other greenhouse gases into the atmosphere, enhancing the greenhouse effect and causing global warming.
