Japan Trench
Japan Trench is part of the Pacific Ring of Fire and it is an oceanic trench situated in northeast of Japan. Recently, a team working on the Japan Trench has managed to drill 8000 metres in the seabed of the Pacific Ocean. This makes it the deepest hole dug ever in the seabed of an ocean
Q1. Why was the hole dug on the bed of the Pacific Ocean?
The hole was dug to extract a sediment core which is 120 foot long. This was done so that scientists can study about the earthquake history of the Japan Trench.
Q2. What was the procedure of the digging?
The digging was done with the help of a long drill known as giant piston corer. This drill was used by a research vessel named Kaimei. It took 2 hours and 40 minutes to drill 8000 metres.
Q3. What is Pacific Ring of Fire?
The region around the rim of the Pacific Ocean where many volcanic activities and earthquakes occur is known as the Pacific Ring of Fire. The ring is shaped like a horse shoe and is 40,000 kilometres long.
Q4. What is an Oceanic Trench?
Oceanic Trenches are the deepest part of the ocean and they are long and narrow depression on the floor of the sea.
