Semester Review: Astronomy

Front

What is the solar system?

Back

The solar system is a collection of celestial bodies, including the Sun, planets, moons, asteroids, comets, and meteoroids, that are bound by gravity.

Front

Why is it difficult to create a model of the solar system?

Back

The solar system is so big and the objects in it are so small in comparison.

Front

What is gravitational pull?

Back

Gravitational pull is the force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What happens to gravity as the distance between two objects increases?

Back

As the distance between two objects increases, the gravity between them decreases.

Front

What causes day and night on Earth?

Back

The rotation of the Earth on its axis causes day and night.

Front

What is a waxing gibbous moon?

Back

A waxing gibbous moon is a phase of the moon where more than half of the moon is illuminated, but it is not yet full.

Front

What is the role of the Sun in the solar system?

Back

The Sun is the central star of the solar system, providing light and heat, and its gravitational pull keeps the planets in orbit.

Front

What is planetary motion?

Back

Planetary motion refers to the movement of planets around the Sun in elliptical orbits due to gravitational forces.

Front

How does increasing mass affect gravitational pull?

Back

Increasing the mass of an object increases its gravitational pull on other objects.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of an object around its own axis, while revolution is the movement of an object around another object.
