Alfred Wegener named his single supercontinent ____________, which means "all Earth" in ancient Greek.

• Pandora

• Gandowandaland

• Pangea

• Percia

What evidence did Wegener use to support his hypothesis?

• Continents and fossils fitting together/matching-up like puzzle pieces

• glacier scars and other climate evidence from temperature

• mountain ranges and rocks line up across continents

• all of the above

Sedimentary rocks are made up of

• large rocks.  

• hard rocks.

• mostly igneous rocks

• small particles of sediment.

According to the diagram, how does a sedimentary rock become a metamorphic rock?

• Weathering and Erosion

• Heat and Pressure

• Compaction and Cementation

• Melting

Fossils are more likely to form in which type of rock?

• Sedimentary rocks form in layers which help keep fossils from being destroyed.  

• Metamorphic rocks form by being exposed to a lot of heat and pressure and this keeps the fossils from being destroyed.

• Igneous rocks form when lava or magma cools and this keeps the fossils from being destroyed

• Fossils only form in igneous rocks.

Thinking about sedimentary rock, the oldest layers are found

• on the top most layer

• in the middle of other layers

• all layers are the same age

• towards the bottom
