- Rocks wear away one another through abrasion: ______
- Limestone is dissolved underground by water and carbonic acid to form a cave: ______
- Iron ores within rocks are oxidized forming rust: ______
- A plants roots wedge into the cracks of a stone, breaking it in two: ______
- Water freezes and cracks open large cracks within a boulder: ______

- Alfred Wegener used which of the following to help justify his theory of continental drift: Circle three that apply:
- Continents appeared to be moving very fast
- Fossils of warm weather species found in cold regions of the earth
- Continents such as Africa and South America which appeared to fit like puzzle pieces
- Continents float on the ocean like boats; and must move with the ocean currents
- Fossils of the same species found on both sides of the Atlantic Ocean.
- Human fossils were found along with dinosaur fossils in many places
- Which type of plate boundary could be modeled by two arrows pointing at one another
- Transform
- Divergent
- Convergent
New ocean floor / Mid-ocean ridge / Mountains / Subduction zone
Trench / Sea floor spreading / Rift valley / Plates sliding past one another
Use the words or phrases above for the next three questions
- Which of the above would be associated with a divergent boundary:
- ______
- ______
- ______
- ______
- Which of the above would be associated with a transform boundary:
- ______
- Which of the above would be associated with a convergent boundary:
- ______
- ______
- ______
- A subduction zone is an area where:
- Old ocean floor creates mountains
- Old ocean floor of one tectonic plate dives beneath another tectonic plate
- Old ocean floor contains many hot spots which create long island chains in a region
- Old ocean floor creates a mid-ocean ridge
- Which type of boundary would be modelled with the following image:
______
- Which type of boundary would be modelled with the following image:
← →______
- The Ring-of-Fire is an area
- Around the Pacific where there are many subduction zones
- Around the Atlantic where there is an mid-ocean ridge
- Around Africa where a rift valley is slowly pulling the continent apart
- Surrounding the arctic ocean causing winter ice to melt
- The mechanism for tectonic plates to move around on earth’s surface is:
- Still unknown
- Floating continents move on ocean currents
- Convection currents in the earth’s mantle
- Magnetic currents from the earth’s core
- The formation of a mountain is most likely the result of:
- Weathering
- Erosion
- Plate tectonics
- Deposition
- Deposition is most likely to occur at:
- The top of a mountain
- Halfway up a hill
- A river delta
- The beginning of a river
- Through the processes of weathering and erosion, a river valley over time should become:
- Deeper
- A mountain
- A hillside
- Weathering and erosion do not change river valleys
