However, I can provide you with some notes on structure and physiography in Geography for Class 11 (XI):

Structure:

- Refers to the physical characteristics of the Earth's crust, including rocks, minerals, and landforms.
- The Earth's crust is made up of tectonic plates that move and collide with each other, causing earthquakes, volcanic eruptions, and the formation of mountains.
- The three main types of rocks are igneous, sedimentary, and metamorphic.
- Landforms include mountains, valleys, plains, plateaus, and canyons.

Physiography:

- Refers to the study of the physical features of the Earth's surface, including landforms, climate, and vegetation.
- The Earth's surface is divided into continents and oceans, with different physiographic regions.
- Climate and vegetation are influenced by factors such as latitude, altitude, and proximity to water bodies.
- Different physiographic regions have distinct characteristics, such as the Amazon rainforest in South America and the Himalayan mountains in Asia.

Understanding the structure and physiography of the Earth is essential for studying geography and understanding the processes that shape our planet.
