* Example - Ganga Basin
Trellis Pattern -
* Trellis river system has a rectangular pattern throughout.
* This pattern develops in areas of strong structural central.
* Example - Narmada River System

The latitudinal extent of India is 3214 km from north to south. This spread of this extension is advantageous to the country in the following ways :
(i)The southern part of the country lies within the tropics while the northern part lies in temperate or sub-tropic zone. These variation in the climates is useful for the agricultural activities.
(ii)The latitudinal extension is responsible for large variations in land forms, soil types and vegetation in the country.
(iii)Different types of forests are found in the country due to the north-south latitudinal extension.

Spring Tides |
Neap Tides |

Spring tides are the result of the moon and sun working together to exert more pull on the earth's oceans. |
Neap tides are the result of the moon and sun working against each other's pull. |

Difference Between Physical Geography and Human Geography
| Physical Geography |
Human Geography |
| Physical geography Looks at the Natural process of the Earth, such as climate and plate tectonics, wind movements etc | Human geography looks at the impact and behaviour of people and their implications in the physical world |
| Areas of Physical Geography include:
|
Areas of Human Geography include:
|
| Physical geography lays more emphasis on the ‘location’ aspect of the region it currently studies | Human geography concentrates both a “location” and “people aspect as well. For example, a typical study will focus on why the Western-portion of the Indian subcontinent are populated with people of Iranic and Turkish descent |

Gradation is the process of removing unevenness of the land surface and making it a level land. Agents of gradation are running water, wind, glacier, waves, and underground water. Gradation can be of two types- degradation and aggradation.
• Degradation is the process of denudation. It involves weathering, mass wasting and erosion.
• Aggradation is also known as deposition. Eroded materials are deposited in the depressions or lowlands and these areas rise up.

The flow of water through well-defined channels is known as ‘drainage’ and the network of such channels is called a ‘drainage system’. The drainage pattern of an area is the outcome of the geological time period, nature and structure of rocks, topography, slope, amount of water flowing and the periodicity of the flow

- Continental drift theory was proposed by Alfred Wegener in 1912.
- It was first put forward by Abraham Ortelius in 1596 before fully being developed by Alfred Wegener.
- The theory deals with the distribution of the oceans and the continents.
- According to Wegener’s Continental Drift theory, all the continents were one single continental mass (called a Super Continent) – Pangaea and a Mega Ocean surrounded this supercontinent. The mega ocean is known by the name Panthalassa.
- Although Wegener’s initial theory did not cover mantle convection until Arthur Holmes later proposed the theory.
- The supercontinent was named Pangaea (Pangea) and the Mega-ocean was called Panthalassa.
- According to this theory, the supercontinent, Pangaea, began to split some two hundred million years back.
- Pangaea first split into 2 big continental masses known as Gondwanaland and Laurasia forming the southern and northern modules respectively.
- Later, Gondwanaland and Laurasia continued to break into several smaller continents that exist today.

Evidence that supports the theory
- The Matching of Continents (Jig-Saw-Fit): The shorelines of Africa and South America facing each other match remarkably.
- Rocks of Same Age Across the Oceans: radiometric dating methods have correlated the rock formation in different continents.
- Tillite: The glacial tillite found in Gondwana system of sediments has its resemblance to six different landmasses of the Southern Hemisphere. Counterparts of this succession are found in Africa, Falkland Island, Madagascar, Antarctica and Australia besides India.
- Placer Deposits: The placer deposits of gold in the Ghana coast do not have source rock in the region. The gold deposits of Ghana have been derived from the Brazil plateau when the two continents lay side by side
- Distribution of Fossils: identical species of plants and animals adapted to living on land or in freshwater are found on either side of the marine barriers. For example remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America.

Where earthquake waves are not reported, such zones are called earthquake shadow zones.
It is observed that seismographs located beyond 103° from the epicenter do not record the earthquakes.
Seismographs located beyond 142° again record ‘p’ waves only.
The entire zone beyond 142° do not receive ‘s’ waves
The shadow zone of ‘s’ waves is much larger than the ‘p’ waves it is equal to 40% of the earth surface
