Definition of the word "erosion"
What is the process of rocks breaking down as they move from one location to another.
In colder locations, this type of wedging will occur.
What is ice wedging
Volcanoes form a pattern around this ocean
What is the Pacific Ocean
Definition of "landslide"
What is a large mass of rocks/earth sliding down a mountain.
Where is the Ashfall Fossil Bed located?
What is Nebraska, USA
In the process of erosion, rock edges become...
What is smoother
In warmer locations, this type of wedging will occur
What is root wedging
What type of volcano has thin lava? What type of volcano has thick lava?
What is shield volcano and cone volcano
Two main causes of landslides
What are rain and slope angle
What killed the prehistoric animals 11 million years ago?
What is a volcano with thick lava erupted over 1000 miles away. Over time, the ash traveled to Nebraska and slowly suffocated the animals that were living there.
In the process of erosion, rocks are this size
What is smaller
What are root/ice wedging?
What is when seeds/water go into cracks of rocks and grow/freeze.
The pattern volcanoes form around the ____ Ocean is in this shape. Bonus 100: What is this called?
What is the shape of a ring or horseshoe.
Bonus:The Ring of Fire.
Current engineering design to prevent/protect from landslides
What is:
- steps
- nets
- bridges
How did the bones end up underground?
What is a layer of ash settled over the animal's bodies. Over time, nearby mountain ranges weathered down and were broken into sand, clay, gravel, and small rocks. The sediment was carried by rivers through the fossil beds and was deposited on top of the land.
Given more distance to fall, rocks are more/less eroded?
What is more eroded
Root and ice wedging do this to rocks
What is break them down
What are two types of lava rock we learned about?
What is felsite and basalt.
Landslides are considered dangerous because______.
What is in this natural disaster, rocks and boulders can flow and crash into homes, destroying them.
What changes in the land uncovered the fossils?

Teacher prompt: Map Key (4)
What is yes, it is possible for a volcano to pop up in this location.
Teacher prompt: Select your design (6)
What is solution #2 (+more practical, less time, good amount of $)
How many fossils have been uncovered in the Ashfall Fossil Bed? (Whoever has the closest guess will get the points)
What is about 200
