Deforestation is the cutting down the trees and vegetation cover.It affects the environment due to the following reasons: *The life of all the biotic species are threatened as the basic utility of our life ;oxygen cannot be obtained as trees give us oxygen. *Also the life cycle gets disturbed as many biotic species depend on trees for food. *Fewer forests means large amount of greenhouse gases released into the atmosphere. *It also disturbs the water cycle as trees release water through transpiration. *There is no stooping for soil erosions if trees are not there as they hold the soil firmly with their roots. *The normal environment due to deforestation fets polluted which imposes a great threat to the ozone layer which acts as overall defence for the earth.

There are many facilities which need to be provided to everyone. These are known as public facilities. Examples: healthcare, sanitation, electricity, public transport, schools, colleges, drinking water, etc.

One important characteristic of public facility is that once it is provided its benefit can be shared by many people. For example; if a school comes up in a locality, many children are benefited from that school. Similarly, if a road is built through a village then many people are benefited from the road.

The North Star or Pole Star – aka Polaris – is famous for holding nearly still in our sky while the entire northern sky moves around it. That's because it's located nearly at the north celestial pole, the point around which the entire northern sky turns. Polaris marks the way due north. Pole Star is a star which appears stationary from the Earth. Imagine a straight line passing through these stars . Extend this imaginary line towards the north direction ( nearly five times the distance between the two stars). This line will lead to a star , known as the Pole Star ( North Star ).

If the speed of an object is faster than the other object then we can say that an object is moving faster than another .
On a road we can easily spot the difference in speed of different moving object by simply looking at them, if we look at the position of vehicles at one instance of time and then again at the same vehicles after 5 seconds we can spot which vehicle moves the faster and which vehicle moves the slower, the distance moved by an object in a given instance of time will help us decide its speed, like for example in a 100m race, we can say who has the highest speed by looking at who covers 100m in the shortest time, if we have an idea of time and distance we can easily determine the speed.
