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

Which of the following is an example of an opposing signal? no examplthates given.   i would say, that traffic lights in a city at major intersections direct the flow of traffic in opposite directions so would be an example.also, stop signs on either side of the same street would be an example. at a train crossing, the light for allowing car traffic in opposite directions or not would be another example.
