Explanation / Answer

ANSWER-

9. D) VOLCANISM.

the volcanism is the process of eruption of molten magma onto the surface of the earth or a solid-surface planet or moon,where pyroclasts ,lavas and volcanic gases erupt to the surface and changes the planet morphology.

10. A) HYDROGEN.

sun is made up of hydrogen (70%) ; helium(28%);Carbon,nitrogen,oxygen make up 1.5% and 0.5% made up of other elements such as neon,iron,silicon,magnesium and sulfur.

11. B) BASIN FLOODING.

12. A) CRATERING .

ALSO KNOWN AS METEOR IMPACT.

13. C) THE PLANET IS SHROUDED WITH CLOUDS.

aldebo 0.1 indicates high water molecules.

14. A) SAME AS CLASSIFYING A STAR BY ITS TEMPERATURE.

15. B) TEMPERATURE DIFFERENCES.

Payne was able to accurately relate the spectral classes of stars to their actual temperatures by applying the ionization theory developed by Indian physicist Meghnad Saha.
