I WONDER - How Is A Sedimentary Rock Formed?

Sedimentary rocks form through various processes, such as the compression of sand or mud by water or ice, or the accumulation of shells and other materials on the ocean floor. Sediments carried by rivers to the ocean floor eventually become rock, a process known as livification.

What are some ways sedimentary rocks can form?

• Through volcanic eruptions

• By the compression of sand or mud layers

• By the melting of glaciers

• Through the evaporation of water

Which of the following materials can contribute to the formation of sedimentary rocks?

• Shells and other ocean materials

• Molten lava

• Sunlight

• Wind

What role does water play in the formation of sedimentary rocks?

• It melts the rocks

• It dissolves the rocks

• It colors the rocks

• It compresses layers of sediment

What happens when a river carries sediment to the ocean?

• The sediment settles on the ocean floor

• The sediment turns into lava

• The sediment evaporates

• The sediment floats on the surface

What is the term for the process where sediment becomes rock?

• Livification

• Erosion

• Crystallization

• Metamorphism
