Multiple Choice

Ocean, floodplain, rainforest and beach are all examples of...?

• Sediment

• Layers

• Environments

• Formations

Multiple Choice

In which of these environments is gravel most likely to build up?

Multiple Choice

Why is gravel most likely to build up in that environment?

• The fast moving water is able to push it along

• The waves are able to move it around

• The plants help to keep it n place

• The sand cements together to form gravel

Multiple Choice

What is calcium carbonate most likely made up of?

• Grass

• Tree bark

• Sea shells and coral

• Mud

Multiple Choice

Which of the following is an example of an observation?

• The environment of the upper layer of the rocky outcrop was a deep ocean when it formed millions of years ago

• Mosasaurus fossils show that they had paddle shaped fins and a strong tail

• Lepidodendron probably grew in floodplains

• The Mosasaurus was a good swimmer

Multiple Choice

Which of the following is an example of an observation?

• Millions of years ago, Desert Rocks National Park was some sort of watery environment

• The Devil's Postpile was created when a huge volcano erupted

• Some areas that are now deserts were once covered by an ocean

• The Devil's Postpile is made of smooth dark rocks with no fossils

Multiple Choice

Which of the following is an example of an inference?

• There is a lot of sand on the beach

• The conglomerate rock looks like it is made of several small pebbles cemented together

• The environment of the lower layer of the rocky outcrop was a floodplain when it formed

• The mosasaurus skeleton is 18 meters long

Multiple Choice

Which of the following is an example of an inference?

• The Mosasaurus lived in an ocean environment

• The conglomerate rock looks like it is made of several small pebbles cemented together

• Siltstone forms in slow moving water

• The sandstone has layers that are different colors

Multiple Select

Which of the following are examples of conglomerate rock? (Choose 2)

Multiple Select

Which of the following are examples of sandstone? (Choose 2)

Multiple Choice

How do rocks provide information about what an environment was like in the past?

• If the rocks in an environment are red, we know that the past environment was very sunny

• Conglomerate rocks can form in any environment, therefore it is impossible to determine past environments if we find conglomerate rock

• Different sediment builds up in different environments. Therefore, different kinds of sedimentary rocks form in different environments

Open Ended

What can you infer by the fact that there are 2 rock layers in the rocky outcrop of Desert Rocks National Park?

Multiple Choice

When writing a scientific argument, we answer a question with a(n)

• response

• evidence statement

• inference

• claim

Multiple Choice

Which of the following is the best example of a claim for a good scientific argument?

• A Mosasaurus is the most fierce dinosaur that ever lived

• The environment of the lower layer of the rocky outcrop was a floodplain when it was formed

• Desert Rocks National Park is in the Southwestern United States

• Mortoniceras had a soft body inside of a shell

Multiple Choice

Which is the best example of evidence that could be used support the claim that Desert Rocks National Park was once under water?

• Mososauras had paddle shaped fins and a strong tail that allowed it to swim

• Desert Rocks National Park was once under water

• The upper layer of the rocky outcrop was a deep ocean environment when it formed

• Desert Rocks National Park is a fun place to visit

• The type of sediment changes in each location

• The 3 locations move to different parts of the land

• The mountain environment becomes the beach environment

Multiple Choice

If we see different kinds of rock layers in one location, what can we infer about what has happened in that location over time?

• Different rocks existed at different times

• A different type of mountain used to be there

• The actual location of the environment has moved

• The sea level has changed
