    The ultimate source of water

    • Rain

    • Rivers

    Correct Answer
    A. Rain
    Explanation
    Rain is considered the ultimate source of water because it is a natural process of water cycle where water evaporates from the earth's surface, condenses in the atmosphere, and eventually falls back to the ground as rain. This precipitation replenishes the water bodies like rivers, lakes, and underground aquifers, which in turn provide water for various purposes such as drinking, irrigation, and industrial use. While rivers are a significant source of water, they are ultimately dependent on rainwater for their supply. Therefore, rain can be considered as the primary and ultimate source of water.

    The water bearing layer of the earth

    • Crust

    • Mantle

    Correct Answer
    A. Crust
    Explanation
    The crust is the outermost layer of the Earth and is the water-bearing layer. It is the thinnest layer, ranging from 5-70 kilometers in thickness. The crust contains both landmasses and ocean basins, and it is where all the Earth's water bodies, such as lakes, rivers, and oceans, are located. This layer is composed of various types of rocks, including sedimentary, igneous, and metamorphic rocks. The crust plays a vital role in supporting life on Earth as it provides a habitat for various organisms and is also a source of important resources like minerals and fossil fuels.

    Three forms of water

    • Ice, Rain, Water

    • Snow, Lake, River

    Correct Answer
    A. Ice, Rain, Water
    Explanation
    The correct answer is Ice, Rain, Water because these three forms represent the different phases of water. Ice is the solid form of water, rain is the liquid form that falls from the atmosphere, and water is the general term for liquid water. These three forms demonstrate the various states that water can exist in depending on temperature and pressure conditions.

  • 5. 

    Water is the main source of water

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Water is indeed the main source of water. This statement is true because water is the primary and essential component required for the existence of water itself. Without water, there would be no source of water. Therefore, it is logical to conclude that water is the main source of water.

    Rate this question:

  • 6. 

    Water is how many percent of water

    • 96

    • 71

    Correct Answer
    A. 71
    Explanation
    The question is asking what percentage of water is water. Since water is 100% water, the answer is 100%. However, none of the answer choices match this, so the closest option is 71%.

    How to minimise the use of water

    • Drip Irrigation

    • By using taps

    Correct Answer
    A. Drip Irrigation
    Explanation
    Drip irrigation is a method of watering plants by delivering small amounts of water directly to the roots of the plants. This technique helps to minimize water usage by reducing evaporation and runoff. Unlike traditional methods where water is sprayed over a large area, drip irrigation ensures that water is delivered precisely where it is needed, resulting in less wastage. By using drip irrigation, water can be conserved and used more efficiently, making it an effective way to minimize water usage.

    Rate this question:

  • 8. 

    Fresh water is available everywhere

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Fresh water is not available everywhere. While water covers about 70% of the Earth's surface, the majority of it is saltwater in the oceans. Only a small percentage of water is freshwater, and most of it is locked in ice caps and glaciers, making it inaccessible for human use. Additionally, some regions may experience water scarcity due to factors like droughts or pollution. Therefore, it is incorrect to say that fresh water is available everywhere.

    Rate this question:

  • 9. 

    We should save water

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Saving water is important because it is a finite resource that is essential for all living beings. By conserving water, we can ensure that there is enough for everyone's needs, as well as for agriculture, industry, and the environment. Additionally, saving water also helps to reduce energy consumption and the cost of water treatment and distribution. Therefore, it is crucial to save water to protect our planet's resources and ensure a sustainable future.

    Rate this question:

  • 10. 

    Water shortage is due to

    • More rainfall

    • By wastage of water by industries

    Correct Answer
    A. By wastage of water by industries
    Explanation
    Water shortage is caused by the wastage of water by industries. Industries consume large amounts of water for their operations, and if they do not have proper water management systems in place, a significant amount of water can be wasted. This wastage can contribute to the overall scarcity of water, especially in areas where water resources are already limited. Therefore, the wastage of water by industries is a significant factor in causing water shortage.
