Natural Sciences encompass the study of the natural world through systematic observation, experimentation, and analysis. This broad field includes key disciplines such as physics, which examines the fundamental laws governing matter and energy; chemistry, which explores the composition, structure, and reactions of substances; biology, which investigates living organisms and their interactions; and earth sciences, including geology, meteorology, and astronomy, which address the physical features of Earth and the universe. By employing the scientific method, natural sciences seek to explain phenomena ranging from atomic particles to ecosystems, driving advancements in technology, medicine, and environmental understanding. These disciplines emphasize empirical evidence and are foundational to modern innovation, helping humanity address challenges like climate change and disease.

A. Au
B. Ag
C. Go
D. Gd
Answer: A
Explanation: The chemical symbol for gold is Au, derived from its Latin name “aurum,” which is used in the periodic table to represent this element.
3. Question: What force keeps planets in orbit around the sun?
A. Magnetic force
B. Gravitational force
C. Frictional force
D. Electrostatic force
Answer: B
Explanation: Gravitational force provides the attraction between the sun and planets, maintaining their elliptical orbits as described by Newton’s law of universal gravitation.
4. Question: What process do plants use to convert sunlight into energy?
A. Respiration
B. Photosynthesis
C. Fermentation
D. Digestion
Answer: B
Explanation: Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen, serving as their primary energy source.
5. Question: What is the hardest natural substance on Earth?
A. Gold
B. Diamond
C. Iron
D. Quartz
Answer: B
Explanation: Diamond is the hardest natural substance due to its strong carbon-carbon covalent bonds in a tetrahedral structure, making it highly resistant to scratching.
6. Question: What element is most abundant in the Earth’s atmosphere?
A. Oxygen
B. Carbon dioxide
C. Nitrogen
D. Argon
Answer: C
Explanation: Nitrogen makes up about 78% of the Earth’s atmosphere, playing a key role in maintaining atmospheric pressure and supporting life through the nitrogen cycle.
7. Question: What is the speed of light in a vacuum?
A. 300,000 km/s
B. 150,000 km/s
C. 3,000 km/s
D. 30,000 km/s
Answer: A
Explanation: The speed of light in a vacuum is approximately 300,000 kilometers per second, a fundamental constant in physics that defines the maximum speed of information transfer.
8. Question: What is the primary function of red blood cells?
A. Fight infections
B. Carry oxygen
C. Produce hormones
D. Digest food
Answer: B
Explanation: Red blood cells contain hemoglobin, which binds to oxygen in the lungs and transports it to tissues throughout the body for cellular respiration.
9. Question: What type of rock is formed from cooled lava?
A. Sedimentary
B. Metamorphic
C. Igneous
D. Fossil
Answer: C
Explanation: Igneous rocks form from the cooling and solidification of magma or lava, such as basalt or granite, representing the rock cycle’s volcanic origins.
10. Question: What law states that energy cannot be created or destroyed?
A. Newton’s first law
B. Law of conservation of energy
C. Ohm’s law
D. Boyle’s law
Answer: B
Explanation: The law of conservation of energy states that energy is transformed from one form to another but the total amount in a closed system remains constant.
11. Question: What is the building block of proteins?
A. Glucose
B. Amino acids
C. Fatty acids
D. Nucleotides
Answer: B
Explanation: Amino acids are the monomers that link together to form proteins, which are essential for various biological functions like enzyme activity and structural support.
12. Question: What gas do humans exhale more of than they inhale?
A. Oxygen
B. Nitrogen
C. Carbon dioxide
D. Hydrogen
Answer: C
Explanation: During respiration, humans exhale more carbon dioxide as a waste product of cellular metabolism, while inhaling oxygen for energy production.
13. Question: What causes the phases of the moon?
A. Earth’s shadow
B. The moon’s rotation
C. Sunlight illuminating different parts
D. Atmospheric refraction
Answer: C
Explanation: The phases of the moon result from the changing angles of sunlight as the moon orbits Earth, with varying portions of its illuminated side visible from Earth.
