What is friction?

• A force that accelerates motion between two surfaces in contact.

• A force that opposes motion between two surfaces in contact, slowing down moving objects.

• A type of energy generated by moving objects.

• A force that increases the speed of moving objects.

What is the definition of aquatic habitat?

• A land-based environment where organisms live, such as forests and deserts.

• An environment that is exclusively found in the air, such as the atmosphere.

• An aquatic habitat is a water-based environment where organisms live, such as lakes, rivers, and oceans.

• A man-made environment created for aquatic organisms, such as aquariums.

What controls the pitch of sound?

• The amplitude of sound waves

• The frequency of vibrations

• The speed of sound in air

• The temperature of the medium

What is the difference between pitch and loudness?

• Pitch refers to how high or low a sound is, while loudness refers to how soft or loud a sound is.

• Pitch is the volume of a sound, while loudness is the frequency of a sound.

• Pitch refers to the duration of a sound, while loudness refers to the quality of a sound.

• Pitch is the intensity of a sound, while loudness is the tone of a sound.

What is the relationship between force and motion?

• Force is a type of energy that cannot change an object's motion.

• Force is any push or pull that can cause an object to move or change its motion.

• Force is the speed at which an object moves in a straight line.

• Force is the mass of an object multiplied by its velocity.

What is camouflage?

• A method of hiding by blending in with the environment, helping animals avoid predators.

• A technique used by hunters to track animals more effectively.

• A type of clothing designed to make soldiers less visible in combat.

• A strategy employed by animals to attract mates.

What is gravity?

• Gravity is the force that repels two bodies away from each other.

• Gravity is the force that attracts two bodies towards each other, giving weight to physical objects.

• Gravity is the energy that allows objects to move freely in space.

• Gravity is the phenomenon that causes objects to float in water.

What is the importance of vibrations in sound production?

• Vibrations create sound waves; the frequency of these vibrations determines the pitch of the sound.

• Vibrations are irrelevant to sound production.

• Vibrations only affect the volume of the sound.

• Vibrations can only be heard, not felt.

What is the role of the skeleton in animals?

• To provide strength, support, and protection for the body, and aids in movement.

• To produce hormones that regulate metabolism.

• To store fat and energy for the body.

• To facilitate the exchange of gases in the respiratory system.

What is refraction?

• The bending of light as it passes from one medium to another, causing objects to appear broken or displaced, like a straw in water.

• The process of light being absorbed by a medium without any change in direction.

• The reflection of light off a surface, creating a mirror image.

• The scattering of light in different directions as it passes through a medium.
