    The main sequence is a diagonal area on the H-R diagram that includes more than 90 percent of all stars. It represents the stage in a star's life where it is fusing hydrogen into helium in its core, thus producing energy and maintaining its stability. Stars in the main sequence are in a state of equilibrium, where the inward gravitational force is balanced by the outward pressure from nuclear fusion. This phase is the longest and most stable stage in a star's life cycle.

    The inner layer of the sun’s atmosphere that gives off its visible light; the sun’s surface

    • Corona

    • Radiation Zone

    • Photosphere

    Correct Answer
    A. Photosphere
    Explanation
    The photosphere is the inner layer of the sun's atmosphere that gives off its visible light. It is considered the sun's surface because it is the layer that we can directly observe and see as the bright disk of the sun. The photosphere is responsible for the majority of the sun's light and heat that reaches the Earth.

    The sediments deposited directly by a glacier.

    • Till

    • Moraine

    • Rock Sediment

    Correct Answer
    A. Till
    Explanation
    Till is the correct answer because it refers to the sediments that are directly deposited by a glacier. When a glacier moves, it carries and transports a variety of materials, such as rocks, sand, and clay. As the glacier melts, it drops these materials, creating a mixture of unsorted sediments known as till. Till can vary in size and composition, containing a range of particles from large boulders to fine-grained clay. The deposition of till is a significant process in glacial landscapes and can contribute to the formation of landforms like moraines.

    The movement of an object around another object.

    • Revolution

    • Rotation

    • Orbit

    Correct Answer
    A. Revolution
    Explanation
    Revolution refers to the movement of an object around another object. This term is commonly used in astronomy to describe the orbit of planets around the sun or the moon around the Earth. It implies a circular or elliptical path followed by the object as it revolves around the central body. Rotation, on the other hand, refers to the spinning or turning motion of an object around its own axis. Orbit is also related to the movement of objects around another object, but it specifically refers to the path followed by a celestial body in space.

    • True

    • False

    • IDK.

    • Option 4

    Correct Answer
    A. True
    Explanation
    The statement is true because our Sun is indeed the only star in our solar system. The solar system consists of the Sun, planets, moons, asteroids, comets, and other celestial bodies that orbit around it. While there are billions of stars in the universe, the Sun is unique to our solar system and provides heat, light, and energy for all the planets, including Earth.
