The formation of sedimentary rocks begins with two primary processes of the rock cycle: weathering and erosion. Which of the following statements best describes weathering and erosion?

• Weathering is the process of rocks changing to different types. Erosion is the process of rocks breaking apart.

• Weathering is the process by which rocks break down. Erosion is the process of them being carried away.

• Weathering is the process of rock transportation by water. Erosion is the process of rock transportation by wind.

• Weathering is the process of rocks forming from magma. Erosion is the sediment in an area.

• The regular cola has more volume.

• The diet cola has more volume.

• The regular cola is less dense than the diet cola.

• The diet cola is less dense than the regular cola.

Based on cell theory, where do cells, the basic unit of life in all livings, originate?

• They form from synthesis of inert gases found in the atmosphere.

• They form when carbon dioxide combines with water and solar energy.

• They form from preexisting cells that divide and multiply.

• They form when preexisting cells absorb other preexisting cells from the same species.
