Q2 exam review (waves & space) 2024

Front

What are spring tides?

Back

Spring tides occur during the full moon and new moon phases when the gravitational forces of the moon and sun align, resulting in higher high tides and lower low tides.

Front

What are neap tides?

Back

Neap tides occur during the first and third quarter moon phases when the gravitational forces of the moon and sun are perpendicular, resulting in lower high tides and higher low tides.

Front

True or False: During a total solar eclipse, no sunlight can be seen from anywhere on Earth.

Back

False. During a total solar eclipse, the moon blocks sunlight from reaching only certain areas on Earth, not all.

Front

What causes day and night on Earth?

Back

Earth's rotation causes day and night, taking approximately 24 hours to complete one full rotation.

Front

What is the role of Earth's axis during its revolution around the Sun?

Back

Earth's axis remains pointed in the same direction at all times as it revolves around the Sun.

Front

What type of waves are emitted by all warm bodies and used in remote controls?

Back

Infrared waves are emitted by all warm bodies and are commonly used in remote controls.

Front

What is the difference between Earth's rotation and revolution?

Back

Rotation is the spinning of Earth on its axis, taking 24 hours, while revolution is the orbit of Earth around the Sun, taking approximately 365 days.

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation with wavelengths longer than infrared light, used for communication.

Front

What are microwaves?

Back

Microwaves are electromagnetic waves with wavelengths shorter than radio waves, used in cooking and communication.

Front

What is the significance of the full moon phase?

Back

The full moon phase is significant for spring tides, as it represents the time when the moon is fully illuminated and aligned with the Earth and Sun.
