Definition

1. Noun:
   • Mountain system: A major, interconnected group of mountains, ranges, and associated geological structures formed by the same large-scale tectonic processes.
   • Mountain range (in a systemic context): A series of mountains or ridges that are geologically linked and form a distinct, continuous unit within a larger orogenic (mountain-building) system.

Usage Examples

• Noun:
  • Himalaya là một sơn hệ đồ sộ của châu Á. (The Himalayas are a massive mountain system in Asia.)
  • Các nhà địa chất nghiên cứu sự hình thành của sơn hệ Andes. (Geologists study the formation of the Andes mountain system.)
  • Sơn hệ Trường Sơn có ảnh hưởng lớn đến khí hậu Việt Nam. (The Truong Son mountain system has a major influence on Vietnam's climate.)

Advanced Usage

• The term "sơn hệ" is more formal and scientific than the more common "dãy núi". It emphasizes the geological coherence and systematic origin of the mountains, often used in academic, geographical, or geological contexts.

Variants and Related Words

• Dãy núi (n): Mountain range. This is the more general and commonly used term.
  • Dãy núi Alps rất nổi tiếng. (The Alps mountain range is very famous.)
• Hệ thống núi (n): Literally "mountain system"; a direct synonym for "sơn hệ".
• Mạch núi (n): Mountain chain; similar to "dãy núi" but can imply a linear, connected series.

Synonyms

• Mountain system
• Mountain chain (in a geological sense)
• Orogenic belt (a more specialized geological term)

Notes on Usage

• "Sơn hệ" is a Sino-Vietnamese word (from 山系 ). It is primarily used in written, technical, or formal descriptions rather than in everyday conversation. In most general contexts, "dãy núi" is the preferred term.
