Front

How do we reconstruct the history of our own solar system?

Back

By observing patterns in distant nebulae.

Front

What initially causes dust and gas to draw together in the formation of planets?

Back

Mutual gravitational attraction.

Front

What shape does the material forming a planet take as it accumulates?

Back

A flat disk shape.

Front

What causes the particles in a nebula to begin to swirl and accumulate?

Back

The centrally directed force of gravity.

Front

What role does gravity play in the formation of stars?

Back

It contributes to the coalescence of gases to form a star.

Front

What is a nebula?

Back

A large cloud of gas and dust in space, often the birthplace of stars.

Front

Define gravitational attraction.

Back

The force that pulls two masses toward each other, crucial in the formation of celestial bodies.

Front

What is the significance of satellite images in studying Earth?

Back

They provide valuable data about Earth's surface, atmosphere, and changes over time.

Front

Explain the process of star formation.

Back

Stars form from the gravitational collapse of gas and dust in a nebula, leading to nuclear fusion.

Front

What is the role of gravity in the solar system?

Back

Gravity keeps planets in orbit around the sun and governs the motion of celestial bodies.
