The correct option is C.
The key process of rock cycle include the following: crystallization, erosion and sedimentation and metamorphism. During the erosion and sedimentation stage, the weathering process breaks down rock particles into smaller pieces. These smaller pieces are transported via erosion to other locations, where they form soils.
Earth’s atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. This makes the existence of life possible on Earth. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide. The amount of carbon dioxide on these planets can range from 95% to 97%. This may be the reason no life exists on these planets.
The atmosphere of Venus is about 96 per cent carbon dioxide, with surface temperatures around 737 K (464 °C, or 867 °F).
Venus itself rotates only once every 243 Earth days.
Mars, in contrast, has a thin atmosphere composed of about 95 per cent carbon dioxide, with the remainder being mostly diatomic nitrogen.
The answer would be C) Shifting of sea floor due to movement of tectonic plates. (Huge waves need an abrupt force to cause them)
