The height of a ridge rising from the seafloor can vary significantly depending on the specific ridge in question. For instance, mid-ocean ridges, which are underwater mountain ranges formed by tectonic activity, can rise several kilometers above the surrounding ocean floor. The average height of these ridges is typically around 2 to 3 kilometers, but some sections can be even taller. Overall, the exact height depends on geological processes and local topography.

What ridge has the slowest rate of seafloor spreading?

The Mid-Atlantic Ridge has one of the slowest rates of seafloor spreading, averaging about 2.5 cm per year. This ridge is located in the Atlantic Ocean and is less active compared to other spreading ridges like the East Pacific Rise.


What seafloor is the process by which new crust is created when the seafloor moves apart and magma rises up?

This process is called seafloor spreading. It occurs at mid-ocean ridges where tectonic plates are diverging, allowing magma to rise from the mantle and solidify to create new oceanic crust. As the new crust forms, it pushes the older crust away from the ridge, leading to the continuous expansion of the seafloor.


What is one phenomenon that is considered evidence of seafloor spreading?

The Mid Atlantic Ridge


What is the largest most obvious feature on the seafloor?

The largest and most obvious feature on the seafloor is the mid-ocean ridge system, which is a continuous underwater mountain range formed by tectonic plate movements. This system, stretching over 40,000 miles, includes the Mid-Atlantic Ridge and is characterized by volcanic activity and rift valleys. It plays a crucial role in seafloor spreading and is the site of significant geological processes. Additionally, the ridges are prominent features that can rise thousands of meters above the surrounding ocean floor.


Which plate boundary creates new land like the seafloor at the mid-Atlantic ridge?

A divergent plate boundary creates new land like the seafloor at the mid-Atlantic ridge. At these boundaries, tectonic plates move away from each other, allowing magma to rise up and solidify, forming new oceanic crust. As the crust cools and spreads outward, it creates new land in the form of the ocean floor.

The mid-Atlantic ridge is spreading faster than the East Pacific Rise?

The Mid-Atlantic Ridge is actually spreading slower than the East Pacific Rise. The rate of seafloor spreading along the Mid-Atlantic Ridge is estimated at about 2.5 centimeters per year, while the East Pacific Rise spreads at a rate of about 5 centimeters per year.


Where is active seafloor spreading occurring today?

At any divergent plate margin: The Mid-Atlantic Ridge The boundary between the African Plate and Arabian Plate (the Red Sea) Great Rift Valley West Antarctic Rift East Pacific Rise Pacific-Antarctic Ridge Galapagos Rise Gakkel Ridge


How does the age of seafloor bedrock vary with distance from a mid-ocean ridge?

The age of seafloor bedrock increases with distance from a mid-ocean ridge. At the ridge, the bedrock is young, as it is continuously being formed by volcanic activity. As it moves away from the ridge through the process of seafloor spreading, it cools and ages over time.


Is ocean crust formed at a mid ocean ridge?

Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.


Is it true that as the new seafloor moves away from the ridge and becomes hotter it moves upward and forms still higher ridges?

Yes, it is true. As the new seafloor forms at mid-ocean ridges and moves away, it cools and becomes denser. The denser seafloor sinks lower, creating space for more magma to rise at the ridge, forming still higher ridges.


Who first related the symmetrical magnetic patterns in seafloor basalt to seafloor spreading at a mid ocean ridge?

What structure on the seafloor would have magnetic striping?

A mid-ocean ridge would have magnetic striping on the seafloor. This striping is caused by the alternating polarities of Earth's magnetic field recorded in the basaltic rocks as they cool and solidify at the mid-ocean ridge, providing evidence for seafloor spreading.
