B when is spins it means its rotating east and west directions
D. Weathering
The six steps of the rock cycle includes Weathering and Erosion, Transportation, Deposition, Compaction and Cementation. Metamorphism, Rock Melting.
Deposition is the process where rock particles sink at the rivers and become sediment.
Weathering is the process by which wind and water breaks down igneous, sedimentary, and metamorphic rocks. The process refers to large rocks broken down into smaller pieces and the broken off particles stay in the area.
B = although each ray of light follows the law of reflection,
v2 = v1 + at
60 = v1 + 4*10 v1 = 20 m/s
