Sediments on earth's surface sometimes differ in composition from the underlying bedrock. what can you conclude from this observation?

a. bedrock is broken down by weathering.
b. bedrock is formed from sediments.
c. erosion moves sediment to new locations.
d. sediments are formed from the local bedrock.

The bedrock is known as the solid, hard rock which is present beneath of the surface materials, such as the gravel and the soil. The bedrock may be composed of granite, while the sediments having a different composition than them are transported from different areas. The sediments can be moved from one place to another by the processes such as erosion. This transportation leads to their different compositions of the bedrock and sediments.

Hence, the answer is option (c) - erosion move sediments to new locations.

Understanding seed structure is helpful in understanding seed functions. Seeds have an outer seed coat that varies from thin and papery to rock-hard. ... The seed leaves, or cotyledons, can also hold a food supply. The food supply supports the sprouting seedling until it grows a root and can make its own food
