The atmosphere exerts a tremendous amount of pressure on everything on the Earth, includ ing us. Explain why we are not crushed under this weight?

Explanation

**Step-by-Step Solution:**

1. **Understanding Atmospheric Pressure:**
The atmosphere exerts pressure on all objects on Earth, including humans. This pressure is due to the weight of the air above us. At sea level, atmospheric pressure is approximately 101,325 Pascals (Pa).

2. **Internal Pressure in the Body:**
Our bodies contain fluids, such as blood, which exert pressure outward. The pressure inside our bodies (internal pressure) is balanced with the atmospheric pressure outside. This balance is crucial for maintaining our physical structure.
