What are tides?

Back

Tides are the rise and fall of sea levels caused by the gravitational forces exerted by the moon and the sun on Earth.

What is the position of the Earth during a new moon?

Back

During a new moon, the moon is positioned between the Earth and the sun, making it invisible from Earth.

Front

What causes the seasons on Earth?

Back

Seasons are caused by the tilt of Earth's axis and its orbit around the sun, leading to varying sunlight and temperatures.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, and gamma rays.

Why do some telescopes need to be in orbit?

Back

Some telescopes need to be in orbit to observe wavelengths of light that are blocked by Earth's atmosphere, such as gamma rays.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two bodies toward each other, depending on their masses and the distance between them.

Front

What happens during a full moon?

Back

During a full moon, the Earth is between the sun and the moon, allowing the entire face of the moon to be illuminated.

Front

What is the significance of the North Pole's tilt?

Back

The tilt of the North Pole affects the amount of sunlight received in the Northern Hemisphere, influencing seasonal changes.

Front

What is a comet?

Back

A comet is a small celestial body made of ice, dust, and rocky material that orbits the sun, often developing a tail when close to it.

Front

What is the role of gravity in predicting comet collisions?

Back

Gravity helps scientists understand the orbits of comets and planets, allowing them to predict potential collisions.
