23.1 Exploring the Solar System Concepts

Front

What is a protoplanetary disk?

Back

A rotating disk of dense gas and dust surrounding a young star, where planets can form.

Front

What process is essential for the formation of a protoplanetary disk?

Back

Collapse of a nebula under its own gravity.

Front

Which planet is the largest in our solar system?

Back

Jupiter.

Front

What is a nebula primarily composed of?

Back

Gas and dust.

Front

What role do Jovian planets play in the stability of the solar system?

Back

They stabilize the solar system by their gravitational influence, which helps to clear debris.

Front

What are planetesimals?

Back

Small celestial bodies that combine to form planets, varying in composition.

Front

How do planetesimals contribute to planetary diversity?

Back

They vary in composition, leading to diverse planetary compositions as they combine to form planets.

Front

What is the significance of the gravitational influence of Jovian planets?

Back

It helps to maintain the stability of the solar system by clearing debris and preventing collisions.

Front

What is the main difference between terrestrial and Jovian planets?

Back

Terrestrial planets are rocky and smaller, while Jovian planets are gas giants and larger.

Front

What is the primary composition of gas giants?

Back

Mostly hydrogen and helium.
