Question

Why we couldn't live without atmospheric pressure?

A) It enables us to breathe and supports our respiratory system.
B) It regulates our body temperature.
C) It provides protection from harmful cosmic radiation.
D) It plays a role in the water cycle.

Answer 1

Atmospheric pressure is essential for human survival as it enables breathing, regulates body temperature, provides protection from cosmic radiation, and affects the water cycle.

Step-by-step explanation:

The atmospheric pressure is essential for human survival due to several reasons:

1. It enables us to breathe and supports our respiratory system. The atmospheric pressure ensures that air is pushed into our lungs when we inhale, allowing oxygen to enter our bloodstream and carbon dioxide to leave our body when we exhale.

1. It regulates our body temperature. The atmospheric pressure helps maintain a stable temperature and prevents our body from overheating.

1. It provides protection from harmful cosmic radiation. The layers of the atmosphere shield us from most of the harmful cosmic radiation that would otherwise reach the Earth's surface.

1. It plays a role in the water cycle. Atmospheric pressure affects the evaporation and condensation of water, which is crucial for the water cycle.
