Save water save life
Water is essential for survival but is becoming scarce as the global population grows. Only 1% of the world's water is easily accessible for drinking. Many regions already face water scarcity due to lack of access to safe, clean water (quality scarcity) or insufficient water supplies (quantity scarcity). If current trends continue, more than 3 billion people may suffer from water shortages by 2025. Small changes like turning off the tap while brushing teeth can save over 200 liters of water per month. It's important to conserve water to ensure future generations have enough for basic needs.
Prevention of water pollution
To prevent water pollution, dispose of garbage properly in waste bins and not in streets or gullies. Also dispose of chemicals, oils and medicines correctly, not down sinks or toilets. Use water wisely by not letting taps run unused and reducing washing water, which can prevent shortages and less dirty water needing treatment. Do not overuse pesticides and fertilizers near seas or oceans to reduce harmful runoffs into water sources.
Water
Water is the most valuable resource for survival. It is essential for all life on Earth and is required for many daily activities from cooking and washing to transportation of food and waste in our bodies. While gold, houses, and diamonds have value, no human could survive without access to clean water for more than a week. The document encourages various ways to conserve water through practices like collecting rainwater, turning off taps, and only watering plants as needed to avoid waste and depletion of groundwater supplies.

Water in our life!
This document discusses water and its importance. It notes that water is essential for life and covers 71% of the Earth's surface. Water exists in various states across the planet, from liquid in oceans and rivers to solid ice and vapor in clouds. It goes through continuous circulation between these states. The document also discusses how water is used by living things and in religions, but can become polluted, harming the environment and life. Proper preservation and management of water resources is important.
Bodies of water
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water can change between liquid, solid, and gas states in this cycle. In its purest form, water is a chemical compound made up of two hydrogen atoms and one oxygen atom. Bodies of flowing water include rivers, creeks, brooks, and canals, which vary in size and flow. Bodies of non-flowing water include oceans, lakes, ponds, reservoirs, sloughs, marshes, and estuaries, and also vary in size and salinity.

This document discusses water structure, properties, scarcity, pollution, and quality management. It provides details on water treatment processes for wastewater, drinking water, and groundwater. Water structure is explained, noting water is made of polar H2O molecules that form hydrogen bonds. Scarcity of fresh water is addressed, with over 1 billion people lacking access. Water pollution from various human and natural sources contaminates supplies. Treatment methods like screening, sedimentation, and disinfection aim to remove solids and pathogens before water is returned safely to the environment or for drinking. Ongoing water quality management is needed through monitoring and adaptive practices.
Omari
Water is essential for life and makes up 70% of the human body. It exists in three forms - liquid, solid (ice), and gas (water vapor). Liquid water is found in oceans, lakes, rivers, and underground, while water vapor is present in the air as clouds and fog. Water is made of hydrogen and oxygen and can dissolve many substances, making it a universal solvent. Proper storage and treatment of sewage and oil spills are needed to prevent water pollution, which can spread disease and harm health. Education is important to teach people how to properly dispose of waste and keep water sources clean.
Water
Water is made up of hydrogen and oxygen molecules and covers over 70% of the Earth's surface. It exists in three states - solid, liquid, and gas - and is essential for all living things. The water cycle describes how water is constantly recycled as it evaporates from bodies of water into the air, condenses into clouds, and falls back to the Earth as precipitation. It is important to conserve our limited water resources through practices like reducing consumption and matching water levels to load sizes. Singapore has campaigned to lower daily water usage and aims to reduce consumption to 140 liters per person by 2030.
Edu653watercycle
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from bodies of water and condenses into clouds, where it falls as precipitation and either runs off into other bodies of water or is absorbed by soil, starting the cycle again. Key processes in the water cycle include evaporation, condensation, precipitation, and runoff. The water cycle is essential to sustaining life and natural systems on Earth.
Science primary 4 states of water
The Egyptians were the earliest recorded people to treat water over 1,500 years ago by boiling, heating in the sun, or using heated iron to clean water. They also filtered boiling water through sand and gravel.
Water exists on Earth in solid, liquid, and gas forms and is essential for all living things. It moves continuously through the water cycle by evaporating from bodies of water and the ground, condensing in the sky as clouds, and falling back to the ground as precipitation.
Today, cities treat drinking water through processes like chlorination to kill germs and make water safe for human consumption.
Ravi raj sharma
This document discusses water on Earth. It states that water exists in solid, liquid, and gas forms in our solar system, and that two-thirds of Earth is covered by water. While the total quantity of water on Earth is around 1386 lakh cubic meters, only 0.33% of that is available for direct human use, found mainly in rivers, lakes, and groundwater. The document also describes the water cycle by which water is constantly recycled through evaporation, precipitation, and runoff, keeping the overall amount of water on Earth relatively constant. Key uses of water mentioned include agriculture, drinking, washing, fire extinction, recreation, and industrial applications.
Water consumption &purification
- Most of Earth's water is saltwater found in oceans, while only 3% is freshwater. Of this freshwater, over two-thirds is frozen in glaciers and ice sheets.
- Water is continually cycled through the Earth in the hydrological cycle between oceans, atmosphere, and land via evaporation, condensation, precipitation, and infiltration. This cycle provides freshwater for human and ecosystem uses.
- Groundwater makes up about 96% of unfrozen freshwater and provides 25-40% of the world's drinking water by flowing through aquifers. However, groundwater quality can be impacted by natural and human-caused contaminants.
The Water Cycle
The water cycle describes the continuous movement of water on, above, and below the Earth's surface, driven by energy from the sun. Water can exist in three states: liquid, gas, and solid. The main stages are evaporation, transpiration, condensation, and precipitation. While a critical process for all life, human activities like wasteful water usage and pollution can negatively impact the water cycle. Personal choices around conserving water and reducing pollution are important to help sustain this essential cycle.
The importance of water
Water is essential for life and good health. It transports nutrients, aids digestion and metabolism, and removes waste from the body. Most health officials recommend drinking at least 8 glasses of clean water per day. Water can also aid in weight loss by suppressing appetite and helping the body burn stored fat. However, much of the Earth's water is contaminated, so point-of-use water treatment systems are necessary to provide clean drinking water.
WATER CYCLEpptx
The water cycle describes how water is constantly circulated and recycled around the Earth. Water evaporates from bodies of water and transpires from plants into the atmosphere due to heat from the sun. Water vapor in the atmosphere condenses to form clouds and precipitates as rain or snow back to the Earth. Runoff and groundwater storage replenish bodies of water, completing the cycle which is crucial for life on Earth and regulates weather patterns.
Water, unit7
Water is a necessary resource for life that exists in three states: liquid, solid, and gas. It can be found in oceans, rivers, lakes, underground, as snow in mountains, and as ice at the poles. The water cycle describes how water evaporates from bodies of water into vapor due to heat from the sun, condenses into clouds, and falls back to earth as precipitation where it collects in bodies of water to repeat the cycle. Proper water management through reservoirs is important, as not all water is safe for drinking and some areas face water scarcity.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
