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
Why the Earth looks blue
Three parts water, one part land.
Almost three-fourths of the Earth is water and a little over one-fourth is land. From far away that makes the planet look blue. The first astronauts to see it whole called it the blue planet.
💡 Key Idea
Seas, bays and gulfs
The ocean reaching inland.
The very largest bodies of water are oceans. Their narrower arms reaching into the land carry names of their own — sea, bay, gulf. These are extensions of an ocean, not separate bodies of water.
💡 Key Idea
Landmass or continent?
One word means big, the other means unbroken.
A landmass is any large body of land. A continent is a large CONTINUOUS stretch of it. Continuous is the word doing the work. Every continent is a landmass; not every landmass is big enough to be a continent.
💡 Key Idea
The five oceans
Five names, one body of water.
The Pacific, the Atlantic, the Indian, the Southern (or Antarctic) and the Arctic. Find each on a map before you go further. Almost everything else in this chapter hangs off those five names.
💡 Key Idea
Ordering the five
Biggest to smallest.
Pacific largest, then Atlantic, then Indian, then Southern, with the Arctic smallest. You can see it on a map without measuring. The Pacific is so wide that most world maps have to split it across both edges.
💡 Key Idea
The boundaries are conventions
Made of nothing at all.
Ask what the dividing lines on the map are made of. Nothing. They are agreements that give us a way to talk about parts of one huge body of water. Seawater crosses them constantly.
