Rocks, Fossils and Fossil Fuels

Sediments can turn into a Sedimentary Rock.

What helps it stick together in one piece?

• Small minerals fill the spaces and cement it together.

• Organisms get trapped and decay into glue.

• Bacteria changes the sediment into cement.

• Heat melts the sediment and it is fused together

Fossil B is an ancient marine mollusk that has been found in tall mountains. This tells us that-

• Fossils can be carried up a mountain.

• The rocks at the top of the mountain used to be underwater.

• The rocks at the top of the mountain used to be in the desert.

• It is impossible that marine mollusks existed in the past.

Answer explanation

The word "marine" tells us that it is a sea creature. This means that the rocks at the top of the mountain were once at the bottom of the ocean.

Which picture shows an example of compaction when making sedimentary rocks?

• 
• 
• 
• 

Answer explanation

Heat and pressure press down and compact the rocks together so that there is less empty space.

• 

Answer explanation

Small minerals fill the spaces and cement it together after compaction.
