- Ocean deposits usually consist of unconsolidated sediments, which can come from various sources, and are deposited at the ocean floor. Thickness of these deposits vary greatly from one ocean to another. They can be differentiated into following categories.
- The Muds: These are terrigenous deposits because they are derived from land and mainly deposited on the continental shelves. The muds are referred to as blue, red and green muds; their colouring depends on their chemical content. Hence pair 2 is correctly matched.
- The Oozes: These are pelagic deposits because they are derived from the ocean. They are made of shelly and skeletal remains of marine microorganisms with calcareous and siliceous parts. Oozes have a very fine and flour like texture and either occur as accumulated deposits or float about in suspension. Hence pair 1 is correctly matched.
- The Clays: These occur mainly as red clays in deeper parts of the ocean. Red clay is an accumulation of volcanic dust blown out from volcanoes during a volcanic eruption. Hence pair 3 is correctly matched.

Correctly Matched Ocean Deposits Origin:
Ocean deposits originate from various sources and can be categorized based on their origin. Let's analyze the given pairs to determine which ones are correctly matched.
1. Ooze : Pelagic deposit
- Ooze deposits are formed from the accumulation of tiny skeletal remains of marine organisms that settle in the deep ocean.
- These deposits are known as pelagic deposits because they are found in the pelagic zone of the ocean, away from the continental margins.
2. Muds : Terrigenous deposit
- Mud deposits consist of fine-grained particles such as silt and clay that are eroded from the continents and transported to the ocean by rivers and currents.
- These deposits are referred to as terrigenous deposits due to their terrestrial origin from the land.
3. Red Clay : Volcanic dust deposit
- Red clay deposits are composed of fine particles that include volcanic ash and dust, as well as other materials that settle on the ocean floor over time.
- These deposits are associated with volcanic activities and are often found in regions where volcanic eruptions have occurred.
Therefore, all three pairs given above are correctly matched:
- Ooze is indeed a pelagic deposit.
- Muds are indeed terrigenous deposits.
- Red Clay is indeed a volcanic dust deposit.
Hence, the correct answer is option 'D' - 1, 2, and 3.
