Suppose the distance between earth and sun becomes half of its present distance. What is likely to happen to life?

Explanation

To analyze the effects on life if the distance between the Earth and the Sun were to become half of its current distance, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Current Distance**: The average distance between the Earth and the Sun is approximately 149.6 million kilometers. If this distance is halved, it becomes 74.8 million kilometers.

2. **Relate Distance to Time Period**: The time period of Earth's orbit around the Sun is related to the distance from the Sun. According to Kepler's Third Law, the square of the time period (T) is proportional to the cube of the semi-major axis (r) of the orbit:
