Answer:
divergent boundary on land
Explanation:
Divergent boundary involves the crustal spreading of two tectonic plates. Divergent boundary is the separation or rifting apart of two plates. Divergent boundary can occur between oceanic plates or continental plates.
Divergent boundary between oceanic plates , the convection currents lift the lithosphere producing a mid oceanic ridge. Extensional forces spreads the lithospheric plate apart causing an in flow of magma from the interior of the earth. The magmatic materials travels through fissure and oceanic ridges to the surface of the ocean floor. The volcanic material/magma later solidifies to form new oceanic crust with the youngest rock closest to the mid oceanic ridge.
Divergent boundary between continental plates , the convection current usually pull the continental plates upward due to the thickness of the continental plates. The continental plates are pulled thin by the extensional forces resulting to fracture. The fracture result into a rift shaped structure. Rift valleys are formed which is a lowland region. The two parts of the continents(lands) that are separated are likely to develop fault on both sides of the rifts. The fractured area along the rift valley is a region prone to earthquakes.
Rift valley are structures found in divergent boundary between continents(land) and are region of earthquakes activities because of movements and fracturing occurrence. The East African rift is an example of this kind of plates boundary.
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.

The correct answer is - A. San Andreas Fault.
The San Andreas Fault is stretching alongside the western coast of the United States. It is a result of a divergent plate boundary, where the westernmost part of the country is slowly moving away from the North American mainland.
As it moves more and more, this part will come to a situation where the crust will be much thinner and easier to crack under the high pressure, temperatures, and magma from the mantle layer bellow. As this stats to happen, the region, already pretty active geologically, will become even more active geologically, and the stress on the crust will be result in very often and strong earthquakes.
