Question
Arrange the following five zones of the pelagic region of an ocean in the increasing order of its depth from the surface.
1. Mesopelagic
2. Epipelagic
3. Abyssopelagic
4. Bathypelagic
5. Hadopelagic
Choose the correct answer from the options given below:
The correct answer is
2, 1, 4, 3, 5
Ocean Zones Depth Order
The pelagic region of the ocean is divided vertically into distinct zones based on depth. Understanding the order of these zones by increasing depth is crucial in oceanography.
Pelagic Zone Depths
- Epipelagic Zone: The surface layer, extending from the surface down to approximately $200 \text{ m}$. This zone receives sunlight.
- Mesopelagic Zone: Extends from $200 \text{ m}$ to $1,000 \text{ m}$. Often called the "twilight zone," with limited sunlight.
- Bathypelagic Zone: Extends from $1,000 \text{ m}$ to $4,000 \text{ m}$. No sunlight penetrates this zone.
- Abyssopelagic Zone: Extends from $4,000 \text{ m}$ to $6,000 \text{ m}$. Characterized by extreme pressure and cold.
- Hadopelagic Zone: The deepest zone, extending below $6,000 \text{ m}$, typically found in oceanic trenches.
Ordering Pelagic Zones
Arranging the zones in increasing order of depth:
- Epipelagic (Zone 2)
- Mesopelagic (Zone 1)
- Bathypelagic (Zone 4)
- Abyssopelagic (Zone 3)
- Hadopelagic (Zone 5)
The correct numerical sequence representing this order is 2, 1, 4, 3, 5.
Correct Answer Identification
This sequence matches Option B.
