Green house effect is

Options

A. Gardening outside the house
B. Global cooling
C. Global warming
D. Green colour house

Answer

**Step-by-Step Solution:**

1. **Understanding the Greenhouse Effect**: The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth, some of it is reflected back to space and the rest is absorbed, warming the planet.

2. **Role of Greenhouse Gases**: Certain gases in the atmosphere, known as greenhouse gases (like carbon dioxide, methane, and nitrous oxide), trap heat. This is similar to how a greenhouse traps heat to keep plants warm.

3. **Impact of Deforestation**: Deforestation leads to a decrease in the number of trees available to absorb carbon dioxide. With fewer trees, more carbon dioxide remains in the atmosphere, which increases the concentration of greenhouse gases.

4. **Consequences of Increased Greenhouse Gases**: As the concentration of greenhouse gases increases, they enhance the greenhouse effect, leading to an increase in Earth’s average temperature, a phenomenon known as global warming.

5. **Global Warming Effects**: Global warming results in various environmental issues, such as melting glaciers, rising sea levels, loss of habitats for wildlife, and increased frequency of extreme weather events.

6. **Conclusion**: Based on the explanation, the greenhouse effect is primarily associated with global warming rather than gardening, global cooling, or the color of houses.

**Final Answer**: The greenhouse effect is best described as **global warming** (Option C).
