Which of the following are examples of Organisms?

• Dinosaurs

• Ammonites

• Sedimentary Rocks

• Volcanoes

Igneous and sedimentary rocks could each be changed into metamorphic rock if they are changed by -

• weathering.

• organisms.

• pressure.

• cementation.

Trace Fossils are rocks that

• Have body structures of that animal in them

• Have trace amounts of DNA in them

• Have imprints or animal tracks in them

• Have trace amounts of radioactive isotopes in them

What is deformation?

• Process when the rocks break apart or erode.
• Process of when rocks melt away. 
• Process when rocks change shape under pressure.
• Process when 

anything that has mass and takes up space

• matter

• mass

• rocks

• rock transformation

Soil formation begins with the weathering of_______.

• Humus
• Subsoil
• Litter
• Rock

In order to be classified as metamorphic, a rock must have –

• magma cooling underground.

• changed with heat and pressure.

• compacted sediment into layers.

• formed in less than 100 years.

a region of rock that formed together as a single rock type

• rock formation

• sample

• sediment

• subduction

Sedimentary rocks can have layers of different colors. This occurs when –

• molten rock seeps into large cracks underground.

• extreme pressure causes minerals to separate.

• different minerals are deposited at different times.

• seasonal patterns change the rate of erosion.
