Changes in pressure cause wind to blow.
Answer:
Student C.
Explanation:
The student C statement is correct about the disappearing of Saturn's rings. The main reason of disappearing of Saturn's rings is the sloping of the Saturn planet. Saturn has its own orbit in which he revolve around the sun, During its movement, the orbit takes it to a location where the planet seems to tip just enough so that the rings slowly seem to be disappearing. The view of student A is incorrect because the ring is not made of methane gas, it is made of large pieces of comets, asteroids or shattered moons. The view of Student B is also incorrect because there is not just the ice coated dust particle but also pieces of rocks which reflect the light not refracted.
Yes, this is true.

Answer:
Cleavage
Luster
Streak
Hardness
Explanation:
Cleavage is the ability of a mineral to split apart easily along flat surfaces and it is dependent on the mode of formation and properties of the mineral.
Luster is the way light is reflected from the surface of the mineral. Some minerals allows a greater reflection of light due to their shiny surfaces while some don’t.
Streak is the color of the mineral's powder which are its unique components and also helps in the identification of minerals.
Hardness of a mineral can be measured by the Mohs scale. This is usually measured on a scale of 1-10. The hardest being 10 on the scale.
A population pyramid tells us how many dependants there are. There are two groups of dependants, young dependants (aged below 15) and elderly.
