Cascadia's fault line is primarily associated with the Juan de Fuca Plate, which subducts beneath the North American Plate along the Cascadia Subduction Zone. This region features several fracture zones, including the Gorda Ridge and the Juan de Fuca Ridge, which are mid-ocean ridges where new oceanic crust is formed. The tectonic activity in this area is characterized by the interaction of these plates, leading to significant seismic activity, including the potential for large megathrust earthquakes.

What land features are associated with the process of orogenesis at divergent boundaries?
At divergent boundaries, land features associated with orogenesis include rift valleys and mid-ocean ridges. These features form as tectonic plates move apart, causing the crust to stretch and fracture, leading to the creation of new crust and landforms.
What are associated with mid-ocean ridges?
Mid-ocean ridges are associated with volcanic activity, earthquakes, and the creation of new oceanic crust through seafloor spreading. These features form where tectonic plates move apart and magma rises to the surface, creating underwater mountain ranges.
What mountains are associated with divergent plate boundaries?
Mid-ocean ridges, such as the Mid-Atlantic Ridge and East Pacific Rise, are associated with divergent plate boundaries. These underwater mountain ranges form as tectonic plates move apart, allowing magma to rise and create new oceanic crust.
Where are the Ocean ridges are generally located?
Ocean ridges are generally located along the boundaries of tectonic plates, primarily in the middle of oceans. They form where two plates are diverging, allowing magma to rise and create new oceanic crust. Notable examples include the Mid-Atlantic Ridge in the Atlantic Ocean and the East Pacific Rise in the Pacific Ocean. These ridges are characterized by volcanic activity and are often associated with seismic activity.
what type of boundary do mid ocean ridges occur?
Mid-ocean ridges occur at divergent boundaries, where tectonic plates are moving apart. As the plates separate, magma rises from the mantle to fill the gap, creating new oceanic crust. This process leads to the formation of underwater mountain ranges and is often associated with volcanic activity. Additionally, mid-ocean ridges play a crucial role in seafloor spreading.

What are Mendocino Molokai and Galapagos are names of fracture zones in the floor?
Mendocino, Molokai, and Galapagos are names of fracture zones in the ocean floor, where tectonic plates are moving away from each other. These fracture zones are characterized by a series of faults and ridges that form due to the movement of the Earth's tectonic plates. They play a significant role in shaping the geology and topography of the ocean floor.
What are hackle marks?
Definition: Fine ridges on a fracture surface, parallel to the direction of propagation of the fracture. source: About.com
Which is associated with mid-ocean ridges?
Mid-ocean ridges are associated with seafloor spreading, where new oceanic crust is created as tectonic plates pull apart. This process allows magma to rise from beneath the Earth's surface and solidify, forming new crust along the mid-ocean ridge. The presence of hydrothermal vents, volcanic activity, and earthquakes are also characteristics of mid-ocean ridges.
True or False Mid-ocean ridges are actually underwater mountain ranges?
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are long, seismically active submarine ridges associated with seafloor spreading.

Which type of boundary do mid-ocean ridges occur?
divergent
What type of boundry is mid ocean ridge?
The main boundary associated with mid-ocean ridges are divergent boundaries, because the plates move away from eachother, or "diverge".
Segments of mid-ocean ridges are offset relative to each other by?
fracture zones
What mountains are associated with divergent plate boundaries?
