5th Six Weeks Science Review

What type of energy transformation occurs in a microwave?

• Chemical → Electrical → Radiant

• Electrical → Thermal, Light, and Mechanical

• Radiant → Chemical

• Mechanical → Chemical

How does energy flow in a flashlight?

• Electrical → Mechanical → Thermal

• Radiant → Chemical → Electrical

• Chemical → Electrical → Radiant

• Thermal → Radiant

What is the primary energy conversion in plants during photosynthesis?

• Thermal → Chemical

• Radiant → Chemical

• Electrical → Thermal

• Chemical → Radiant

The principle of energy conservation states:

• Energy can be destroyed under certain conditions.

• Energy is created from chemical reactions.

• Energy cannot be created or destroyed, only transformed.

• Energy only flows in one direction.

In a battery-powered circuit, the energy transformation sequence is:

• Thermal → Chemical → Electrical

• Chemical → Electrical → Light

• Electrical → Radiant → Mechanical

• Chemical → Mechanical → Radiant

When plants store energy in glucose, the type of energy is:

• Electrical

• Radiant

• Thermal

• Chemical

What happens to the energy stored in plants when consumed by another organism?

• All energy is transferred to the consumer.

• Part of the energy is used by the consumer, and some is released as thermal energy.

• Energy is converted into mechanical energy only.

• Energy remains as chemical energy.

Spring tides occur when:

• The Sun, Moon, and Earth form a right angle.

• The Sun, Moon, and Earth are aligned.

• The Moon is closest to the Earth.

• The Moon is farthest from the Earth.

Neap tides occur during which Moon phases?

• New and Full Moons

• First and Third Quarter Moons

• Waxing Crescent and Waning Gibbous

• All Moon phases

Which factor has the greatest effect on the size of tides?

• Earth’s tilt

• Earth’s revolution

• The Moon's distance from Earth

• Sunlight intensity
