Boundaries
What are the three types of boundaries?
Convergent, Divergent, Transform Boundaries
Broken parts of lithosphere that carry continents and oceans
What are tectonics plates? What are lithospheric plates?
Name at least three natural disasters that are caused by plate tectonics?
Volcanic Eruptions, Earthquakes, Tsunamis,
What is the process called that breaks apart rocks and other objects into smaller sediments? (Hint: it is NOT erosion)
What is weathering?
Who came up with the theory of continental drift?
Alfred Wegner
What type of boundary is it when two plates slide past each other?
Transform Boundary
What type of boundary is it when crust destroyed due to subduction?
Convergent boundary
What happens when soil on a hill becomes oversaturated with water?
What is a mudslide?
What are the three main forces of erosion we discussed?
What is water, wind and glaciers? (Will also accept organisms)
The Earth is broken into plates under the earth's surface that move because of intense heat.
What is the theory of plate tectonics
When two plates move away from each other
What is a divergent boundary?
What type of boundary is it when new crust forms?
Divergent Boundary
Which country that we discussed had worse destruction than Chile even though they had a smaller magnitude Earthquake?
What is Haiti?
True or False: Erosion is always a slow process
False (mudslides are an example of fast erosion)
The theory that the continents were once connected but have since moved apart?
The theory of Continental Drift
The opposite to mid-ocean ridges, these form at convergent boundaries.
What are deep sea trenches?
When two plates slide with one on top of the other due to differences in density
What is subduction?
What are the names of the two main classes of volcanoes we discussed in class?
What are shield and composite (stratovolcanoes) volcanoes
What is it called when the particles and pieces of rock moved by erosion, settle back down on the surface?
What is sedimentation or deposition?
What is the name for the supercontinent before they drifted to our modern day locations?
Pangaea
The boundary where you would find a mid-ocean ridge?
What is divergent boundary?
What causes plates to move?
Convection Currents in the Asthenosphere
What do you call the point on Earth's surface directly above the origin of an earthquake?
What is the epicenter?
How are valleys formed by glaciers different to valleys formed by rivers?
They have a U shape rather than a V shape
What was unique about the fossils Alfred Wegner found in different continents?
They would not have been able to cross the ocean
