Class 11 Geography - MAHARASHTRA
Structure and Physiography
The chapter 'Structure and Physiography' in Class 11 Maharashtra State Board Geography explores the geological evolution, rock structures, and diverse physical features of India. Students will study how the Indian subcontinent is divided into distinct physiographic divisions such as the Himalayas, the Northern Plains, the Peninsular Plateau, the Coastal Plains, and the Islands. Understanding this chapter is crucial for board exams as it builds the foundational knowledge of India's landforms, drainage patterns, and resource distribution, frequently featuring in map-pointing questions and long-answer descriptive queries.

Physiography
The study of the physical features and landforms of the earth's surface, shaped by internal and external tectonic and geomorphic forces.
Peninsular Plateau
A stable block of ancient crystalline rocks that formed part of the ancient Gondwanaland, making it the oldest and most stable landmass of India.
Himalayan Mountain System
A young, weak, and flexible fold mountain range formed by the tectonic collision of the Indo-Australian plate with the Eurasian plate.
Northern Plains
Aggradational plains formed by the extensive alluvial deposits brought down by the major Himalayan river systems like the Indus, Ganga, and Brahmaputra.
Coastal Plains
Narrow strips of lowland situated between the Peninsular plateau edges and the Arabian Sea in the west and the Bay of Bengal in the east.

Frequently Asked Questions
What is the main difference between the Western Ghats and the Eastern Ghats?
The Western Ghats are continuous, higher, and block-faulted mountains running parallel to the Arabian Sea, whereas the Eastern Ghats are discontinuous, lower, and eroded by major rivers flowing into the Bay of Bengal.
How were the Himalayas formed?
The Himalayas were formed due to the convergence and tectonic collision of the Indo-Australian plate with the Eurasian plate, which compressed the sedimentary rocks of the Tethys Sea.
Why is the Peninsular Plateau considered stable?
The Peninsular Plateau is composed of ancient crystalline, igneous, and metamorphic rocks that have remained largely undisturbed by severe tectonic folding for millions of years.
