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.
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, prev...
↳ The atmosphere is Earth's protective shield and climate regulator.
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.
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.
This chapter covers the composition and layered structure of Earth's atmosphere, explaining the characteristics of each layer from the troposphere to the exosphere. It then distinguishes between weather and climate, deta...

19 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which two gases are the most abundant in the Earth's atmosphere?
BeginnerNitrogen and Oxygen
Nitrogen (78%) and Oxygen (21%) together make up about 99% of the atmosphere, making them the two primary and most abundant gases.
In which layer of the atmosphere does nearly all weather phenomena, such as rainfall, fog, and hail, occur?
BeginnerTroposphere
The troposphere is the lowest layer, containing most of the water vapour and clouds, and it is where nearly all weather phenomena occur.
Which layer of the atmosphere contains the ozone layer that filters harmful ultraviolet radiation from the Sun?
BeginnerStratosphere
The stratosphere contains a layer of ozone gas which shields the Earth by filtering the Sun's harmful ultraviolet radiation.
What is the primary reason for the formation of the south-west monsoon in India?
IntermediateThe unequal heating of land and sea, creating a low-pressure area over land
During summer, the Indian landmass heats up faster than the oceans, creating a low-pressure area over land, which draws moist winds from the high-pressure ocean towards the land.
