As the Moon moves through the Earth's shadow, it gradually darkens and may appear reddish in color. This phenomenon can be observed from Earth and is a result of the positioning of the Moon, Earth, and Sun in relation to each other.

      Kilometer

    • B.

      Yard

    • C.

      Light Year

    • D.

      Metre

    Correct Answer
    C. Light Year
    Explanation
    A light year is a unit of distance used in astronomy to measure vast distances in space. It is defined as the distance that light travels in one year in a vacuum. Since light travels at a speed of approximately 299,792 kilometers per second, a light year is equivalent to about 9.46 trillion kilometers. This unit is used to describe the distance between stars, galaxies, and other celestial objects, as the distances in space are so vast that using kilometers or meters would be impractical.

    The process by which green plants prepare their food is called _____ ?

    • A.

      Respiration

    • B.

      Photosynthesis

    • C.

      Digestion

    • D.

      Excretion

    Correct Answer
    B. Photosynthesis
    Explanation
    Green plants prepare their food through the process of photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose (food) and oxygen. This process takes place in the chloroplasts of the plant cells, specifically in the chlorophyll pigments. Through photosynthesis, plants convert light energy into chemical energy, which is stored in the form of glucose. This process is crucial for the survival of plants and is responsible for the oxygen production in the atmosphere.

      Asthenosphere

    • C.

      Stratosphere

    • D.

      Atmosphere

    Correct Answer
    A. Lithosphere
    Explanation
    The correct answer is Lithosphere. The lithosphere refers to the rigid outer layer of the Earth, which includes the crust and the uppermost part of the mantle. It is composed of solid rock and is broken into several tectonic plates. This layer is where all the Earth's landforms, such as mountains, valleys, and continents, are found. The lithosphere is crucial for supporting life on Earth as it provides a solid foundation for the biosphere and interacts with other layers of the Earth, such as the atmosphere and hydrosphere.
