What is the difference between greenhouse effect and global warming?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Greenhouse Effect**:
- The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat from the sun. This is similar to how a greenhouse works, where sunlight enters but cannot escape, leading to a warmer environment inside.

2. **Mechanism of the Greenhouse Effect**:
- Sunlight reaches the Earth and warms its surface. Some of this heat is reflected back into space, but greenhouse gases like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) absorb and re-radiate this heat, preventing it from escaping. This process keeps the Earth's temperature at a level suitable for life.
