1. What are Saturn's rings made of? How did they form?

2. What is Titan? Why are scientists interested in it?

3. Why was Pluto reclassified from a planet to a dwarf planet? (Give two reasons.)

1. stones, ice, dust

2. it's saturn's biggest moon

3. because it was too small, it didn't have a clear orbit, there was a lot of garbage

1) ice, dust and rocks

2) titan is saturns largest moon and scientists are interested in it because there are lakes of ethane and methane which are found as gases on Earth

3) pluto has no definite orbit and it is too small to be considered a real planet
