Veda Bites are swipeable micro-lessons — each one teaches exactly one
idea. Here's a taste from this kit; the app has the full deck.
💡 Key Idea
The Atmosphere's Role
Earth's protective gas blanket.
The atmosphere is a blanket of air surrounding the Earth, held by gravity. It is a mixture of gases vital for life. It shields us from harmful ultraviolet (UV) radiation from the Sun and regulates Earth's temperature by trapping some of the Sun's energy, preventing it from escaping back into space.
↳ The atmosphere is Earth's protective shield and climate regulator.
⭐ Important Fact
Primary Gases: Nitrogen and Oxygen
The air we breathe, by numbers.
The atmosphere is composed of a mixture of gases. Nitrogen and oxygen are the two primary and most abundant gases, essential for life.
↳ Nitrogen (78%) and Oxygen (21%) make up 99% of the atmosphere.
💡 Key Idea
Layered Structure of the Atmosphere
Five layers from ground to space.
The atmosphere has a layered structure defined by changes in temperature and density with increasing altitude. The density of air is highest near the Earth's surface and decreases with altitude.
↳ The atmosphere has five distinct layers, each with unique characteristics.
