Class XI

Fundamentals of Physical Geography

  • We live on the earth. Our lives are affected by our surroundings in many ways.
  • Geography studies the ‘spatial organisation’ and ‘spatial integration’.
  • A Geographer is required to have a broad understanding of the spatial reality.
  • Geography equips you to appreciate diversity and investigate into the causes.

UNIT I : GEOGRAPHY AS A DISCIPLINE

“What is geography”? In very simple words, it can be said that geography is the description of the earth. The term geography was first coined by Eratosthenese, a Greek scholar (276-194 BC.). The word has been derived from two roots from Greek language geo (earth) and graphos (description).

UNIT II : THE EARTH

This unit deals with –
Origin and evolution of the earth; Interior of the earth; Wegener’s continental drift theory and plate tectonics; earthquakes and volcanoes

Chapter-2

The Origin and Evolution of the Earth

Galaxies form from nebulae. Dark matter plays a crucial role in their formation. Stars are born within nebulae.

Chapter-3

Interior of the Earth

Scientists study the Earth’s interior through indirect methods like seismic waves and analysis of surface materials. Direct observations are limited to the Earth’s crust.

Chapter-4

Distribution of Oceans and Continents

Scientists now understand that the Earth’s surface and interior are dynamic, with tectonic plates moving due to convection currents. These currents are driven by heat from radioactive decay and residual heat within the Earth.

UNIT III : LANDFORMS

This unit deals with –
Landforms and their evolution, Geomorphic processes — weathering, mass wasting, erosion and deposition; soils — formation

Chapter-5

GEOMORPHIC PROCESSES

Our earth is a playfield for two opposing groups of endogenic and exogenic geomorphic processes

Chapter-6

Landforms and their Evolution

Several related landforms together make up landscapes.
Each landform is a result of the action of geomorphic agent.

UNIT IV : CLIMATE

Atmosphere — compositions and structure; Insolation; Temperature — factors; Pressure belts; Winds and air masses and fronts; tropical and extra tropical cyclones; Precipitation types; World climates classification (Koeppen), greenhouse effect,
global warming and climatic changes

Unit-V Water (Oceans)

Chapter-12

Water (Oceans)

The diverse underwater terrain of ocean from the shallow continental shelf to the deep trenches and mid-ocean ridges.

Chapter-13

Movements of Ocean

Ocean water is dynamic. The horizontal and vertical motions are common in ocean water bodies
