प्रश्न
Give geographical reason
Japan is leading in commercial fisheries.
उत्तर
Japan is leading in commercial fisheries due to following reasons:
- In the coastal area near Japan, warm Kuroshio current meets cold Oyashio current. It results in the abundant growth of plankton which is favourable for fishing.
- Some people residing there have traditional skills required for fishing.
- Lack of land and absence of other protein food makes this country dependent on fish as a staple food.
- Absence of alternate occupations makes fishing a major occupation in this country.
- The use of technology for fishing has also increased here.
- Cold climate in the temperate region such as Japan facilitates the preservation of fish.
- Moreover, nearby forest provides wood for ship building, which aids fishing.

Read the following passage and answer the question given below
|
The word petroleum is derived from the original Latin words petra and olium. Petra means rock and oleum means oil. Petroleum is a mixture of several types of hydrocarbons. The stratified rock in which the remains of marine microbial plant plankton (phytoplankton), algae and bacteria are found; such stratified rocks produce oil and natural gas. The remains of marine flora and fauna are stored at the bottom of the ocean, and silt accumulates and is buried beneath the silt layer. Due to the weight of the sludge and the heat generated from it, the organic matter deposited under the sludge is converted into droplets of fine oil. When the temperature of organic matter is reaches up to 120 degrees Celsius, then the organic matter is converted into oil particles. These oil particles penetrate into the microscopic pores of the rock and thus form rocks with a source of petroleum. Sandstones with high porosity are more likely to contain oil. It consists mainly of biofuels. The fuels currently in use include minerals such as coal, petroleum, natural gas and atoms. |
