Read the following passage and answer the question given below
| In developing countries of the world, the development of infrastructure is very slow. Power supply, network of transport routes, industrial and commercial services, educational facilities are all components that are the skeleton that gives shape and strength to economic business. And the immediate return from that is low. The economy of most developing countries is inefficient and unbalanced. Agriculture provides at least 50% to 90% employment; On the other hand some basic items, e.g. Oil and some rare minerals are becoming increasingly expensive. These countries cannot buy it. Mineral fuels like copper, zinc, tin, etc. are becoming very expensive. Developing countries cannot compete with developed countries in purchasing these goods. It is said that creating potential hydropower in the tropics will solve all these problems, but the cost of building it is huge. |
- Which facilities in developing countries of the world are underdeveloped?
- The economy of a developing country depends on which business?
- Developing countries cannot compete with developed countries in purchasing which goods?
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. |
- How the word petroleum is formed?
- How rocks with petroleum sources are formed?
- Which rock is more likely to contain oil?
- What minerals are present in the fuel currently in use?
