Answer:
FOR 1st QUESTION 2\3 OF WATER IS THE ANSWER
Explanation:
KNOW ONLY ONE ANSWER
Answer:
510.1 million km² land is coverd with water
Water scarcity (water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. Humanity is facing a water crisis, due to unequal distribution (exacerbated by climate change) resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades driven by industry. Water scarcity can also be caused by droughts, lack of rainfall, or pollution land pays an important role fir the population distribution
2 answer. as farmers require fertile land for growing crops this leads to better production for them.To set an industry we need flat plain. Climate also pays important as the suitable climatic conditions are require for far
mers
3 answer Afforestation, land reclamation, regulated use of chemical pesticide and fertilisers and checks on overgrazing are some of the common methods used to conserve land.
4The importance of forests cannot be underestimated. We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
5The most common hazard in forests is forests fire. Forests fires are as old as the forests themselves. They pose a threat not only to the forest wealth but also to the entire regime to fauna and flora seriously disturbing the bio-diversity and the ecology and environment of a region. During summer, when there is no rain for months, the forests become littered with dry senescent leaves and twinges, which could burst into flames ignited by the slightest spark. The Himalayan forests, particularly, Garhwal Himalayas have been burning regularly during the last few summers, with colossal loss of vegetation cover of that region.
Causes of Forest Fire
Forest fires are caused by Natural causes as well as Man made causes
Natural causes - Many forest fires start from natural causes such as lightning which set trees on fire. However, rain extinguishes such fires without causing much damage. High atmospheric temperatures and dryness (low humidity) offer favorable circumstance for a fire to start.
Man made causes - Fire is caused when a source of fire like naked flame, cigarette or bidi, electric spark or any source of ignition comes into contact with inflammable material.
Classification of Forest Fire
Forest fire can broadly be classified into three categories;
Natural or controlled forest fire.
Forest fires caused by heat generated in the litter and other biomes in summer through carelessness of people (human neglect) and
Forest fires purposely caused by local inhabitants
