Explain why water begins to flow towards the ground as soon as we open a tap.

Explanation

### Step-by-Step Solution:

1. **Understanding the Setup**: When we open a tap, we are allowing water that is stored in a pipe or tank to flow out. The tap acts as a barrier that, when closed, prevents water from flowing.

2. **Role of Gravity**: The primary reason water flows out of the tap and towards the ground is due to the force of gravity. Gravity is a natural force that pulls objects towards the center of the Earth.

3. **Water's Initial State**: Before the tap is opened, the water is held in place by the pressure in the pipe and the force of gravity acting on it. When the tap is closed, the water is not free to move.
