 What is the process by which plants convert sunlight into energy called?

Photosynthesis

100

 What is the flow of electric charge called?

Electric Current

100

What is a chemical reaction?

A process in which substances are transformed into different substances with different properties.

100

What is the formula to calculate speed?

Speed = Distance / Time

100

What is the outermost layer of the Earth called?

Crust

200

What are the two main products of photosynthesis?

Oxygen and glucose

200

What is the unit of measurement for electric current?

Ampere (A)

200

What are the reactants and products in a chemical equation?

Reactants are the starting substances, while products are the substances formed after the reaction.

200

What is the SI unit of force?

Newton (N)

200

What is the process by which rocks are broken down into smaller pieces by weathering and erosion?

Mechanical weathering

300

Which pigment in plant cells absorbs light energy for photosynthesis?

Chlorophyll

300

What is the formula for calculating electrical power?

Power (P) = Voltage (V) × Current (I)

300

What is the law of conservation of mass?

The law states that mass is neither created nor destroyed in a chemical reaction; it is conserved.

300

What is the difference between speed and velocity?

Speed is a scalar quantity that only specifies the magnitude of motion, while velocity is a vector quantity that specifies both the magnitude and direction of motion.

300

What is the term for the continuous movement of water on, above, and below the Earth's surface?

Water Cycle

400

In which part of a plant cell does photosynthesis primarily occur?

Chloroplasts

400

What is the term for a material that does not allow electric current to pass through it easily?

Insulator

400

 What is the difference between exothermic and endothermic reactions?

Exothermic reactions release heat energy to the surroundings, while endothermic reactions absorb heat energy from the surroundings.

400

What is Newton's first law of motion, also known as the law of inertia?

An object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity, unless acted upon by an external force.

400

What is the theory that explains the movement of Earth's lithospheric plates?

Plate Tectonics

500

What gas is taken in by plants during photosynthesis?

Carbon Dioxide

500

What is Ohm's Law and what is the formula associated with it?

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance. The formula is V = I × R, where V represents voltage, I represents current, and R represents resistance.

500

What is the difference between a physical change and a chemical change?

 A physical change alters the physical properties of a substance without changing its chemical composition, while a chemical change results in the formation of new substances with different properties.

500

What is the relationship between force, mass, and acceleration, as described by Newton's second law of motion?

The force acting on an object is equal to the mass of the object multiplied by its acceleration. F = m × a.

What is the process by which a solid directly changes into a gas without passing through the liquid state?

Sublimation
