What is an undersea volcanic formation that rises at least 1000 m above the surrounding seafloor?
An undersea volcanic formation that rises at least 1,000 meters above the surrounding seafloor is called a seamount. Seamounts are typically formed by volcanic activity and can host diverse marine ecosystems. They often serve as important habitats for various marine species and may influence local ocean currents. Some seamounts can eventually emerge as islands if they grow tall enough above sea level.

What two ways can platuaes can be formeed?
Plateaus can be formed through geological processes such as volcanic activity, where lava flows create a flat, elevated landform, or through erosion, where surrounding land is worn away, leaving a raised area. Additionally, tectonic forces can uplift large sections of the Earth's crust, leading to the formation of plateaus. Both processes result in the characteristic flat tops and steep sides often associated with plateaus.
What are the steps in arc continent moutain formation?
Arc continent mountain formation typically involves several key steps: First, the subduction of an oceanic plate beneath a continental plate occurs, leading to the melting of the oceanic crust and the formation of magma. This magma rises to the surface, resulting in volcanic activity that forms an island arc. Over time, tectonic forces cause the colliding plates to fold and uplift the continental crust, creating mountain ranges. Erosion and sedimentation further shape these mountains, resulting in the complex topography we see today.
What are the minimum and maximum ages of the island of kauai?
Kauai, known as the "Garden Isle," is estimated to be around 5.1 million years old, making it one of the oldest of the main Hawaiian Islands. The island's geological formation began with volcanic activity, and its current landscape has been shaped over millions of years through erosion and sedimentation. There is no officially recognized "minimum age" for the island, but its oldest landforms and features date back to its initial volcanic eruptions.
What do you call the vertical and horizontal movement of the Earth's crust that produces mountains?
The vertical and horizontal movement of the Earth's crust that produces mountains is called tectonic activity, specifically associated with the processes of plate tectonics. This includes processes such as folding, faulting, and volcanic activity, which can result in the uplift and formation of mountain ranges over geological time scales.
How much percentage of water does Neptune have?
No: there's only volcanic activity
An undersea volcanic formation that does not rise 1000 meters above the surrounding sea floor is called what?
An undersea volcanic formation that doesn't rise 1000 meters above the surrounding sea floor is called a seamount.
What is an undersea volcanic formation that does not rise at least 1000 meters above the surrounding sea floor is called?
An undersea volcanic formation that does not rise at least 1000 meters above the surrounding sea floor is called a seamount. These underwater mountains are formed by volcanic activity and can vary in size and shape.
What is undersea volcanic formation that rises at least 1000 meters above the surrounding sea floor is called?
seamount
What undersea volcanic formation that rises at least 1000 meters above the surrounding sea floor is called a?
seamount
what- An undersea volcanic formation that does not rise at least 1,000 meters above the surrounding sea floor is called a _____.?
sea knoll
What is an undersea volcanic formation that does not rise at least 1000 meters above the surrounding sea floor?
A seamount is an undersea volcanic formation that does not rise at least 1000 meters above the surrounding sea floor. These features are common in ocean basins and can vary widely in size and shape, often forming as isolated peaks or smaller volcanic structures on the seabed.
Are the islands of southern Europe formed by undersea mountains or plains?
The islands of southern Europe, such as Sicily, Sardinia, and the Balearic Islands, are primarily formed by a combination of undersea mountains and volcanic activity. These landforms are geologically diverse, with some areas experiencing volcanic eruptions that have contributed to their formation over millions of years.
Can seafloor spreading cause a tsunami?
Seafloor spreading itself does not cause tsunamis. Tsunamis are typically triggered by seismic events, such as underwater earthquakes, volcanic eruptions, or landslides, which can displace large volumes of water and create powerful waves.
Which undersea volcanic has a flat peak?
Guyot
Process that forms new seafloor?
The process that forms new seafloor is called seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is created through volcanic activity. As magma rises and solidifies, it adds to the seafloor, pushing older crust away from the ridge and creating a continuous process of crust formation.
What is the cause of most tsunami's?
Undersea earthquakes or volcanic eruptions.
What is a undersea mountain chain were new ocean floor is produced?
A mid-ocean ridge is an undersea mountain chain where new ocean floor is produced through volcanic activity. Here, magma rises up from the Earth's mantle and solidifies as it cools, leading to the formation of new crust.
