Map Explorer Lab

Geography is a superpower: find places, measure distances, read secret map codes, and follow a river from mountain to sea. Tap every tab and play.

Elements of a map — tap the glowing spots

Every real map has these “must-have” parts. Click labels on the mini-map.

INDIA — PHYSICAL FEATURES
N ↑
Scale 1 cm = 200 km
Mountains Plains Desert

Symbols
Pick a glowing part

Title · Scale · Direction · Key/Legend · Projection · Symbols — tap any label.

  • Title — what the map is about (top)
  • Scale — real distance vs map distance
  • Direction — North arrow (find places)
  • Key / Legend — meaning of colours & signs
  • Projection — curved Earth on a flat sheet
  • Symbols — roads, rivers, temples…

Compass game — know your directions

Earth spins west → east. North Pole top, South Pole bottom. Four cardinal + four intermediate directions.

N NE E SE S SW W NW

Which direction is between North and East?

Cardinal
N · S · E · W
Intermediate
NE · SE · SW · NW

On maps: North arrow (↑ with N). If no arrow, top = North, bottom = South.

Scale magic — shrink the real world

Scale = Map distance ÷ Ground distance. Example: 1 cm on map = 1 km on ground.

Ground: 5 km
🚗
AB
▼ shrink with scale
Map: 5 cm (if 1 cm = 1 km)
AB

5 cm on map = 5 km on ground

🔍 Large scale
Delhi districts

Small area · lots of detail · e.g. 1 cm = 1 km · topo maps

🌏 Small scale
All of India

Large area · less detail · e.g. 1 cm = 100 km · atlas / wall maps

Types of maps — purpose & content

Physical map

Mountains, plains, plateaus, rivers, lakes, oceans

Political map

Countries, states, boundaries, capitals

Thematic map

One theme: rainfall, crops, population, languages…

Why maps rock: fold them in your bag · pack huge info in little space · guide you in new places · show change over time · help planners, military, scientists, and your next school project.

Map · Globe · Sketch · Plan — pick the right tool

Symbol decoder — map secret codes

Conventional signs are the same almost worldwide. Colours also talk: Blue = water Green = forests Yellow = farms White = rocky / barren

River journey — mountain to sea 🏔️→🌊

Follow a drop of water. Click stages or press Play.

💧
Source

Where the river begins — often in mountains, hills, a glacier, lake or spring. Example: Bhagirathi from Gangotri glacier.

Tributary joins main river (↑ volume)
Distributary splits near mouth
Delta = Δ shaped deposit

Fold mountains & block mountains — Earth flexes

Anticline & Syncline
  • Anticline — rock layers arch upward
  • Syncline — rock layers trough downward
  • Formed by compression of Earth’s crust
Block mountains & rift valley
  • Faults crack the crust
  • Horst — uplifted block = block mountain
  • Graben — sunk land = rift valley
