What type of soil is found in the river deltas of the eastern coast? Give three main features of this type of soil.
The type of soil found in the river deltas of the eastern coast is Alluvial Soil. It is specifically found in the deltas of the Mahanadi, the Godavari, the Krishna, and the Kaveri rivers.
Three main features of this soil are:
- It consists of various proportions of sand, silt, and clay.
- It is the most widely spread and important soil in India.
- Based on age, it is classified as Bangar (old alluvial) and Khadar (new alluvial). The Khadar soil has more fine particles and is more fertile than the Bangar.
Explanation
The textbook explicitly states under the section 'Alluvial Soils' that this soil is found in the eastern coastal plains, particularly in the deltas of the Mahanadi, Godavari, Krishna, and Kaveri. The features listed are derived directly from the text's description of Alluvial soil's composition (sand, silt, clay), its prevalence (most widely spread), and its classification based on age (Bangar and Khadar).
Solution Steps
Step 1: Identify the soil type mentioned in the context for river deltas of the eastern coast (Alluvial Soil).
Step 2: Locate the section describing Alluvial Soil features.
Step 3: Extract three distinct features: composition (sand, silt, clay), spread (most widely spread), and classification (Bangar vs Khadar).
