Components of Remote sensing:-
The four basic components of Remote sensing system are target, energy source, transmission path and a sensor.
The target is an object or material that is being imaged. Work together to measure and record information about the target.
Without physical contact.
The energy source provides electromagnetic energy to the target.
Classified into two
- Passive System (that is sun, irradiance from earth’s materials)
- Active System (that is energy sources such as radar).
- The electromagnetic radiation interacts with the target, depending on the properties of the target.
- Transmit information from the target to the sensor.
- Sensor is a device to detect the Electro Magnetic Radiation can be classified on the basis of energy received into Passive sensors and Active sensors.
- Passive sensors detect natural radiation that is emitted or reflected by the object. For eg: Cameras
- Active sensors transmit their own signal and measure the energy that is reflected from the target for example Radar.
3. Explain the process involves in remote sensing technology
Processes involved in Remote Sensing:-
Sun is a Energy Source (A) first requirement which provides electromagnetic energy to the target of things.
Sunrays and Atmosphere (B) as the energy travels from its source to the target interact with, the atmosphere second time from the target to the sensor.
Sunrays and Objects on Earth (C) energy interacts with the target depending on the properties of both the target and the radiation.
Recording of Energy by the Sensor (D) after energy emitted from the target, the sensor collects and records the electromagnetic radiation.
Transmission, Reception and Processing (E) the energy recorded by the sensor has to be transmitted, and processed into an image (hardcopy and/or digital).
Interpretation and Analysis (F) the processed image is interpreted, to extract information about the target which was illuminated.
Application (G) the final process is achieved by applying the extracted information for better understanding.
4. What are the advantages of remote sensing?
Advantages of Remote Sensing:-
- This system provides a synoptic view of a wide area in a single frame.

Environmental Issues
I. Choose the correct answer:
1. Natural Nutrient enrichment of streams and lakes is Eutrophication
2. The main cause for natural air pollution Volcanic eruption
3. Contamination of air is called Air pollution
II. Answer the following questions:
1. What is Water pollution?
Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives in it.
2. List out the major Air pollutants.
The source of pollutants is both natural and man-made.
Volcanic eruptions, wind erosion, are the natural causes of air pollution.
The man-made reasons for air pollution are vehicular emission, thermal power plants, industries and refineries.
3. What is Noise pollution?
Human or machine created sound that disrupts the activity or balance of human or animal life is known as noise pollution.
4. What are the major causes of water pollution?
The major causes of water pollution
The first are disease-causing agents. These are bacteria, viruses, protozoa and parasitic worms.
Second pollutant is oxygen demanding bacteria. This causes other organisms in the water such as fish to die.
The third class of water pollutants is water soluble inorganic pollutants such as acids, salts and toxic metals.
5. What is bio diversity?
Biodiversity is the degree of variation of life forms within a given ecosystem.
Acquired land for mining affects biodiversity.
Environmental changes due to mining and dam constructions cause extinctions.
6. How pollution is caused due to bio-medical waste?
Pollution due to biomedical waste is likely to spread diseases dangerous to life.

The effects of acid rain
- Acid rains killed more than 70% of corals in Lakshadweep and Andaman islands.
- Microscopic organisms such as plankton may not survive the food chain will be affected.
- If ocean temperature increases, growth of coral reefs will be affected.
- Other ecosystems such as forests and desert will also be harmed.
- Loss of bio-diversity and extinction of rare species will occur.
- They also change the acidity level of the soil by leaching crucial nutrients. Thus it affects forest vegetation.
- Corals control carbon-di-oxide by turning CO2 in water to limestone shell.
2. What is smog? What are the effects of smog?

3. Give a brief note on Acid rain.
Acid rain:-
- Acid rain was first discovered in 1852 in London.
- Caused by gases given out by automobiles or coal burning by power plants.
- The gases that cause the acid rain is sulphur-di-oxide and nitrogen oxides.
- These pollutants combine with water vapour in the presence of sunlight and oxygen and form dilute sulphuric and nitric acids.
- When these mixture precipitates from the atmosphere, it is called as acid rain.
- Acid rain falls down to the earth in all forms of precipitation can harm destroy both natural ecosystems and man-made products.
- Acid rains, killed more than 70% of corals in Lakshadweep and Andaman islands.
