How are fossils created?

• Traces of organisms get turned into stone.
• Dead organisms are quickly buried for millions of years.
• Animals get trapped.
• All of the above

Sedimentary rocks form when broken bits of other rock are deposited and then -

• buried and squeezed and cemented together
• melted by the heat of the Earth's core
• completely dissolved in the salt water of the ocean 
• used by humans as a natural resource

Most sedimentary rock forms in the ocean.  This is because oceans -  

• emit much less pollution that other habitats
• receive the majority of the Sun's energy
• have fewer plants and animals than on land
• are where most bits of broken rock get deposited
