Answer 1

Answer:

sedimentary rocks residue from salt water solution

Answer 2

(D) A student obtained a cup of quartz sand from a beach. A saltwater solution is  poured into the sand and allowed to evaporate. The mineral residue from salt  water solution cements the sand grains together, forming a material that is  most likely an sedimentary rock.

Explanation:

• Sediments are compacted and cemented together to form a material called sedimentary rocks and minerals are formed from the solution.
• The water evaporates forming a crystal.
• The process of forming sedimentary rocks from sediment grains binding together by using natural cements, is called cementation.
• Rock fragments bind together to form sedimentary rocks.
• Grains of sand are melted together to form sandstone.
• Examples of sedimentary rocks are sandstone, rock salt, limestone.
• Therefore, option D is correct.
