Convergent Boundaries
The process of the denser plate being forced below the less dense one
What is subduction?
These are formed as continents split apart and are later filled by oceans
What are rift valleys?
Type of geologic environment common near transform boundaries
What is shearing?
The thin, brittle, upper layer of the Earth composed of the crust and upper mantle
What is lithosphere?
Similar rocks and _______ can be found on different continents
What are fossils?
This fault type occurs when plates are pushed together
What is reverse?
Type of geologic environment common near divergent boundaries
What is tensional?
The scale that earthquakes are measured on
What is Richter?
Another name for the border of the Pacific Ocean due to its intense tectonic side effects
What is Ring of Fire?
The shape of these appear to fit together
What are continents?
These low-down geologic features form at the boundary of convergent oceanic and continental plates
What are deep-sea trenches?
This term describes how the oceans are growing wider along divergent boundaries
What is seafloor spreading?
This fault type occurs when plates slide past one another
What is strike-slip?
This type of tectonic plate tends to be denser, younger, and thinner than the continental type
What is oceanic?
Laser-measured motion studies using these space orbiters
What are satellites?
Type of geologic environment common near convergent boundaries
What is compressional?
This fault type occurs when plates are pulled apart
What is normal?
What is earthquake?
This form of heat transfer occurs in the asthenosphere and is thought to keep the plates in motion
What is convection
The age of these types of ocean-floor rocks decreases as you approach the divergent boundary
What is igneous?
The process of mountain building that occurs when plates collide
What is orogeny?
Underwater mountain ranges formed by magma at divergent boundaries
What are mid-ocean ridges?
Submarine earthquakes can sometimes lead to these devastating waves
What are tsunamis?
Who is Alfred Wegener?
The position and frequency of these and earthquakes
What are volcanoes?
