Topic 12 - Formation of Planetary Systems

Question 1

Tides

Answer 1

Attraction between two objects where things not fixed in place will bulge in the direction of the attraction.

Question 2

Lagrange Points

Answer 2

Positions in space where the gravitation forces of two a two body system produce points where objects can remain easily fixed in position.

Question 3

How did Uranus become tilted

Answer 3

It was hit by a rouge object in space

Question 4

Solar Wind impact the atmospheres

Answer 4

Solar wind ‘blows away’ the atmosphere of planets with weaker gravity

Question 5

Forces within an object

Answer 5

Tidal forces cause it to stretch and elastic forces hold it together

Question 6

Roche Limit

Answer 6

The minimum distance a smaller object will be from a larger one before it gets ripped apart by gravity

Question 7

Relation between gravitational forces and elastic forces

Answer 7

If the forces are equal the object will be a sphere otherwise it will be non-spherical

Question 8

What happens if a planet is too hot

Answer 8

The gases in the atmosphere can escape
