Divergent Boundaries
Plates slowly move away from each other
Describe how plates move at Convergent Boundaries
Describe how plates move at Transform Boundaries
Name a unique Convergent Boundary landform
Trench
This natural disaster occurs when plates collide or slide past one another
Earthquake
What are the 3 steps of Plate Motion at Divergent Boundaries
Step 1: Plates slowly move toward each other
Step 2: Hot magma from the soft solid layer below spews through the opening
Step 3: The soft solid layer from below cools and hardens to the edges of the plates
What are the 3 steps of Plate Motion at Convergent Boundaries
Step 1: Plates slowly move toward each other
Step 2: One plate subducts underneath the other
Step 3: The plate that subducts is destroyed by the soft solid layer of rock below
What is the name of the famous California Transform Boundary
San Andreas Fault
Mid-Ocean Ridge
Earthquakes are natural disasters that occur at what geological speed
Rapidly
What is an example of a landform created at Continental / Continental Divergent Boundaries
Rift Valleys
What is an example of a landform created at Oceanic / Oceanie Convergent Boundaries
Volcanoes and in rare cases trenches
What is the only type of event produced at this boundary
Earthquakes
What is the name of the famous expedition that explored this deep trench
The challenger deep
What was the name of the Country severely affected by the 2004 Tsunami
Sri Lanka
This plate motion process is unique to Oceanic / Oceanic Divergent Boundaries and begins when plates slowly move away from each other
Seafloor Spreading
Mountains are created as a result of these two types of plates colliding?
Continental / Continental Convergent Plates
The Alpine Fault which is part of a famous Transform Boundary is located?
New Zealand
Oceanic Plates = young and dense / rich is rock basalt and metals
Continental Plates = much older and much lighter that oceanic plates / silicon-rich
This natural disaster occurs as a result of underwater earthquakes
Tsunamis
Explain using a CER how the Mesosaurus Fossils ended up so far apart
My claim is that South America and Africa were once connected.
My evidence is that a mid-ocean ridge is located between these two continents.
In science, we know that Mid Ocean ridges can only be created by divergent boundaries which means the continents must have slowly moved apart.
Explain using a CER how two completely different species of fossils could be found on the same continent
My claim is that the continents were once separated.
My evidence is that two unique species of the fossil were found on the same continents.
In science, we know that these animals did not live together and must have been united because of a Convergent boundary.
Explain using a CER why California could not break away from the United States
My claim is that California will not detach from the U.S.
My evidence is that California is located on a Transform Boundary.
In science, we know that at Transform Boundaries plates slide past one another. We also know that the boundary in California runs north to south so if a earthquake did occur California would only shift upwards.
What is the name of the famous deep trench located in the Pacific Ocean
Marianas Trench
What are the three criteria we must meet to build an effective Tsunami Warning System
1. Maximizing average warning time
2. Minimizing false alarms
3. Keeping costs low
