Unit 4 - Solar System

Front

What happens to gravitational pull as distance increases?

Back

Gravitational pull decreases.

Front

Which planets are mostly found in the habitable (Goldilocks) zone?

Back

Inner planets.

Front

What is the second step in the formation of the solar system?

Back

Gravity pulled gas and dust toward the center of the disk, forming the sun.

Front

How would planets travel if gravity was 'shut off'?

Back

In a straight line.

Front

What is the fourth step in the formation of the solar system?

Back

Gravity keeps the planets in orbit around the sun.

Front

Define the habitable zone in the context of the solar system.

Back

The habitable zone, or Goldilocks zone, is the region around a star where conditions are just right for liquid water to exist on a planet's surface.

Front

What role does gravity play in the formation of planets?

Back

Gravity pulls particles together to form planets.

Front

Explain the concept of a solar nebula.

Back

A solar nebula is a large cloud of gas and dust in space that can collapse under its own gravity to form stars and planets.

Front

What is the significance of the sun in the solar system's formation?

Back

The sun forms at the center of the solar system and its gravity influences the orbits of the planets.

Front

What would happen to the planets if the sun suddenly disappeared?

Back

The planets would move in a straight line instead of orbiting the sun.
