The youngest or newest layers of rock are always...

• In the middle

• On the bottom

• On the side of a mountain

• On the top

Which rock layer is the oldest?

• Layer Z

• Layer X

• Layer Y

• All layers are the same age.

Which evidence shows Rock Layer X is the oldest?

• Rock Layer X is the oldest because it is the darkest shade of brown.

• Rock Layer X is the oldest because that is where the most fossils are found.

• Rock Layer X is the oldest because rocks have formed on top of it over time and it is under layers X and V.

• Rock Layer X is the oldest because it is next to the river.

Katie looked at this photo of the Grand Canyon and said that there is no evidence of crustal movement. Is Katie correct? Why or why not?

• Katie is incorrect because there is a big gap in the middle of the Grand Canyon.

• Katie is correct because all of the rock layers are still horizontal.

• Katie is incorrect because Rock layer W is tilted which means there is evidence of crustal movement.

• Katie is correct because there is a river at the bottom of the Grand Canyon.

A T-Rex fossil was found at layer X. This indicates...

• Layer Y was formed above ground and new layers of rock formed above it.

• Layer Y was formed underwater

• Layer X was formed above ground and new layers of rock formed over it.

• Layer X was formed underwater

Which layer was formed underwater and why?

• Rock Layer Z because a Trilobite was a marine animal which shows it was underwater.

• Rock Layer Y because a Horn Coral could have lived underwater.

• Rock Layer X because it is close to the surface and there is a brachiopod fossil there.

• Rock Layer X because the fern leaf and the Dragonfly fossils were terrestrial animals and needed water to survive.

The striations on these rocks were caused by which Earth Process:

• Erosion

• Weathering

• Global Warming

• Flooding

Think of our experiment with the ice cubes and aluminum foil. How do these striations show that a glacier once covered the land in this area?

• This is weathering because water got in the cracks and froze to make the striations and cracks bigger.

• Erosion moves broken pieces of rock over Earth's surface, so wind moved the glacier.

• Erosion moves broken pieces of rock over Earth's surface, so a glacier would have dragged the rocks over the surface to make the striations.

• This is weathering because the rock is splitting in half because of the weight of the glacier.

This photo shows an example of which Earth Process?

• Erosion

• Global Warming

• Plant Life Cycle

• Weathering

Which is the best explanation for why the cracks in the rock were smaller when the tree was smaller?

• It is showing weathering because the rock is not horizontal. Crustal movement occurred which caused the splits in the rock to get bigger.

• It is showing erosion. When the tree was smaller, it wasn't moving the rocks to other places, but since it is bigger they still haven't moved alot.

• It is showing erosion because the wind is blowing the rocks away as it blows the plants. Because the plant is moving in the wind, it is making the rock move as well.

• It is weathering because the rock is being split. When the tree was smaller the cracks were smaller and when the tree got bigger, the cracks in the rock also got bigger.
