Front

What is the shape of the orbital path of most planets in our solar system?

Back

The orbital path is in an ellipse, but looks almost circular.

Front

What size ball would best represent Earth if a 14 cm diameter ball represents Jupiter?

Back

1.2 cm

Front

Why does it take Neptune so long to revolve around the Sun?

Back

Neptune is such a long distance away that it has a large orbital path.

Front

What are the two most abundant gases in Earth’s atmosphere?

Back

Nitrogen and oxygen.

Front

Which planet is most likely to support life from Earth?

Back

Planet C.

Front

What causes the Moon to maintain its nearly circular orbit around the Earth?

Back

The Moon is constantly affected by the unbalanced force of the Earth’s gravity which causes it to continue to orbit the Earth.

Front

What is an elliptical orbit?

Back

An elliptical orbit is an oval-shaped path that an object follows around another object due to gravitational forces.

Front

What is gravity?

Back

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

Front

How does distance from the Sun affect a planet's orbital path?

Back

The farther a planet is from the Sun, the larger its orbital path and the longer it takes to complete one revolution.

Front

What is the significance of balanced forces in maintaining an orbit?

Back

Balanced forces keep an object in a stable orbit, preventing it from spiraling into or away from the object it orbits.
