Pt. A(1, 2 , 3)
Pt. B(3, 2, -1)
Let P(x,y,z)
So, AP = BP
((x-1)² + (y-2)² + (z-3)²)^1/2 = ((x-3)² + (y-2)² + (z+1)²)^1/2
(x-1)² + (y-2)² + (z-3)²) = (x-3)² + (y-2)² + (z+1)²
x² +1 -2x + y² + 4 - 4y + z² + 9 – 6z = x² +9 -6x + y² + 4 - 4y + z² + 1 + 2z
4x – 8z = 0
x – 2z = 0

When the quantity of acids in the raining water is more than the average, then such rain is called 'Acid rain'.

We are aware that normally rainwater has a pH of 5.6.  When the pH of the rainwater drops below 5.6, it is called acid rain.

Acid rain refers to the ways in which acid from the atmosphere is deposited on the earth’s surface. Oxides of nitrogen and sulphur which are acidic in nature can be blown by wind along with solid particles in the atmosphere and finally settle down either on the ground as dry deposition or in water, fog and snow as wet deposition.

Acid rain is a byproduct of a variety of human activities that emit the oxides of sulphur and nitrogen in the atmosphere. As mentioned earlier, burning of fossil fuels (which contain sulphur and nitrogenous matter) such as coal and oil in power stations and furnaces or petrol and diesel in motor engines produce sulphur dioxide and nitrogen oxides.

SO₂ and NO₂ after oxidation and reaction with water are major contributors to acid rain because polluted air usually contains particulate matter that catalyses the oxidation.

2SO₂ (g) + O₂ (g) + 2H₂O (l) → 2H₂SO₄ (aq)

4NO₂ (g) + O₂ (g)+ 2H₂O (l) → 4HNO₃ (aq)

The bad effects of acid rain

• When acid rain falls and flows as groundwater to reach rivers, lakes etc, it affects plants and animal life in the aquatic ecosystem
• Acid rain is harmful to agriculture, trees and plants as it dissolves and washes away nutrients needed for their growth
• It causes respiratory ailments in human beings and animal
• It may also cause corrosion in many buildings bridges, monuments, fencing etc
• It causes irritation in the eyes and skin of human beings
• This rain reduces the lustre of the metals too
• Acid rain damages buildings and other structures made of stone or metal
• The Taj Mahal in India has been affected by acid rain

Concept:

Energy:

• The energy possessed by an object is thus measured in terms of its capacity of doing work.
• The unit of energy is measured by joule (J).

Explanation:

Wood and animal dung:

• Animal manure and wood are two popular energy sources in Indian villages.
• It can be used to produce biogas.
• Biogas is a term used to describe a variety of gases that are created when organic matter breaks down in the absence of oxygen.
• Agricultural waste, manure, municipal trash, plant material, sewage, green waste, and food waste are some of the raw materials that can be used to make biogas.
• In some rural locations, biogas plants can be installed adjacent to homes as simple structures to provide a source of gas for cooking and lighting.

Thus, the common energy source in an Indian village is wood and animal dung.

Additional InformationElectricity:

• Electricity is one of the most commonly used forms of energy.
• The term electricity comes from the Greek word electron which means amber.
• It is converted from mechanical to electrical energy with the help of a prime mover i.e., from the turbine to the generator.

Coal:

• Coal is one of the fuels used to cook food.
• Earlier, it was used in railway engines to produce steam to run the engine.
• It is also used in thermal power plants to produce electricity.

Sun:

• Solar energy, one of the renewable sources of energy, is defined as the transformation of solar energy.

The Correct Answer is Option (3) i.e. Nitrogen Oxides.

• The two most common and hazardous oxides of nitrogen are nitric oxide and nitrogen dioxide.

In the water cycle, the movement of water through the soil is known as percolation.

Key Points

• Water is a cyclic resource.
• It can be used and re-used.
• Water also undergoes a cycle from the ocean to land and land to the ocean.
• The hydrological cycle describes the movement of water on, in, and above the earth.
• The hydrological cycle is the circulation of water within the earth’s hydrosphere in different forms i.e. the liquid, solid, and gaseous phases.

Additional InformationEvaporation

• Evaporation is a process by which water is transformed from liquid to a gaseous state.
• Heat is the main cause of evaporation.

Precipitation

• The process of continuous condensation in free air helps the condensed particles to grow in size.
• When the resistance of the air fails to hold them against the force of gravity, they fall onto the earth’s surface.
• So after the condensation of water vapour, the release of moisture is known as precipitation. This may take place in liquid or solid form.

Transpiration

• It is a process in which excess water is lost in the form of vapours from the aerial parts of the plant.
