  • 2. 

    When fuels such as coal and gaoline are burned, they give off __________ as a waste product.

    • Nitrogen

    • Oxygen

    • Carbon Dioxide

    Correct Answer
    A. Carbon Dioxide
    Explanation
    When fuels such as coal and gasoline are burned, they undergo a chemical reaction called combustion. During this process, the carbon present in the fuels combines with oxygen from the air to form carbon dioxide (CO2) as a waste product. Carbon dioxide is a greenhouse gas that contributes to climate change and global warming.

    Rate this question:

  • 3. 

    Earth's atmosphere is made up of __________, oxygen, water vapor, __________, and particles of liquids and solids.

    • Candy and Helium Helium and Neon

    • Protons and Electrons

    • Nitrogen and Carbon Dioxide

    Correct Answer
    A. Nitrogen and Carbon Dioxide
    Explanation
    The correct answer is Nitrogen and Carbon Dioxide. Earth's atmosphere is primarily composed of nitrogen (about 78%) and oxygen (about 21%). However, it also contains trace amounts of other gases, including carbon dioxide, water vapor, and various particles of liquids and solids.

    Rate this question:

  • 4. 

    Plants and animals take __________ directly from the air and use it to release energy.

    • Neon

    • Oxygen

    • Argon

    Correct Answer
    A. Oxygen
    Explanation
    Plants and animals take oxygen directly from the air and use it to release energy through a process called respiration. Oxygen is essential for the breakdown of glucose molecules in cells, which produces energy in the form of ATP. This process occurs in both plants and animals, allowing them to carry out various physiological functions and sustain life. Neon and argon, on the other hand, are inert gases that do not play a role in energy production or metabolism.

    Rate this question:

  • 5. 

    Clouds form when when water vapor __________ out of the air to form tiny droplets of liquid.

    • Runs

    • Condenses

    • Smoke down

    Correct Answer
    A. Condenses
    Explanation
    Clouds form when water vapor condenses out of the air to form tiny droplets of liquid. Condensation occurs when warm, moist air rises and cools, causing the water vapor to change from a gas to a liquid state. This process is essential for cloud formation, as the cooled air cannot hold as much moisture, leading to the formation of visible water droplets or ice crystals.

  • 6. 

    Oxygen is used to __________________________________________________________________.

    • Light candles or breathe.

    • Blow things up and eat

    • Fill you with energy and cook

    Correct Answer
    A. Light candles or breathe.
    Explanation
    Oxygen is essential for both the process of combustion and respiration. When oxygen combines with fuel, it supports the chemical reaction that produces heat and light, allowing candles to burn. Additionally, oxygen is necessary for the process of respiration in living organisms, including humans, enabling us to breathe and obtain energy from the food we consume.

    Rate this question:

  • 7. 

    Nitrogen makes up _____% of the air. Oxygen makes up _____% of the air. The other _____% are all other gases.

    • 27, 52, 21

    • 78, 21, 1

    • 89, 10, 1

    Correct Answer
    A. 78, 21, 1
    Explanation
    The correct answer is 78, 21, 1. This means that nitrogen makes up 78% of the air, oxygen makes up 21% of the air, and the remaining 1% is composed of other gases.

    Rate this question:

  • 8. 

    Earth's atmosphere makes conditions on Earth suitable for living things by containing __________ and other livin things you need to survive.

    • Oxygen

    • Nitrogen

    • Hydrogen

    Correct Answer
    A. Oxygen
    Explanation
    Earth's atmosphere contains oxygen, which is essential for the survival of living things. Oxygen is required for the process of respiration, where organisms convert food into energy. It is also involved in the combustion of fuels, which is necessary for various human activities. Moreover, oxygen plays a crucial role in the ozone layer, protecting life on Earth from harmful ultraviolet radiation. Therefore, the presence of oxygen in Earth's atmosphere is vital for the survival of living things.

    Rate this question:

  • 9. 

    The amount of water vapor __________ from place to place and from time to time.

    • Varies

    • Increases

    • Reduces

    Correct Answer
    A. Varies
    Explanation
    The amount of water vapor can change or fluctuate from one location to another and also from one moment to another. It is not constant and can vary based on factors such as temperature, humidity, and atmospheric conditions. Therefore, the correct answer is "varies".

    Rate this question:

  • 10. 

    Most oxygen molecules have _____ oxygen atoms.

    • 2

    • 6

    • 3

    Correct Answer
    A. 2
    Explanation
    Oxygen molecules consist of two oxygen atoms bonded together. This is represented by the chemical formula O2. Therefore, the correct answer is 2.

    Rate this question:

  • 11. 

    Each nitrogen molecule consists of _____ nitrogen atoms.

    • 1

    • 8

    • 2

    Correct Answer
    A. 2
    Explanation
    Each nitrogen molecule consists of 2 nitrogen atoms. This is because the atomic number of nitrogen is 7, which means that each nitrogen atom has 7 protons in its nucleus. In order to achieve a stable configuration, nitrogen atoms form a covalent bond with each other, sharing a pair of electrons. This results in a molecule with 2 nitrogen atoms bonded together.

    Rate this question:

  • 12. 

    Earth's atmosphere protects living things from dangerous __________ from the sun.

    • UV Rays

    • Radiation

    • Brightness

    Correct Answer
    A. Radiation
    Explanation
    The Earth's atmosphere acts as a shield, protecting living organisms from harmful radiation emitted by the sun. This radiation includes not only UV rays but also other forms of radiation like X-rays and gamma rays. Without the atmosphere, these high-energy radiations would reach the Earth's surface and cause severe damage to living things. Therefore, the correct answer is radiation.

    Rate this question:

  • 13. 

    Pure _____ only contains gases.

    • Air

    • Water

    • Both A and B

    Correct Answer
    A. Both A and B
    Explanation
    Pure air only contains gases, while pure water only contains liquid. Therefore, the correct answer is "Both A and B" because both air and water can exist in a pure form, but air consists of gases and water consists of liquid.
