What causes volcanoes to form at a spreading plate boundary?
Volcanoes often form at spreading plate boundaries due to the upwelling of hot molten rock from the mantle, creating new oceanic crust. As the plates move apart, magma rises to the surface, leading to volcanic activity. This process is known as seafloor spreading.
What are the two main causes for Harry Hess' mid ocean ridge?
The two main causes for Harry Hess' mid-ocean ridge hypothesis are seafloor spreading and plate tectonics. Seafloor spreading is the process where new oceanic crust is formed at mid-ocean ridges, pushing older crust away. Plate tectonics is the theory that Earth's lithosphere is divided into large plates that move and interact with each other, resulting in geological phenomena like seafloor spreading.
What movement causes continents to grow outward?
The movement that causes continents to grow outward is called seafloor spreading. This occurs at mid-ocean ridges where tectonic plates diverge, allowing magma to come up and create new seafloor. As new seafloor forms, it pushes the continents on either side further apart, leading to the growth of the continents.
What layer causes seafloor spreading?
Seafloor spreading is primarily driven by processes occurring at the mid-ocean ridges, which are located at divergent plate boundaries. This occurs at the boundary between two tectonic plates, where magma rises to the surface, creating new oceanic crust and causing the seafloor to spread apart.
What causes volcanoes to form at spreading plate boundaries?
As two plates spread apart from each other at the boundary, magma that was trapped below wells up between them. This magma can be released in the form of volcanoes or ooze out from rift valleys.
What was the primary force that causes the seafloor to spread and continents to drift?
The primary force driving seafloor spreading and continental drift is mantle convection. Heat from Earth's core causes the mantle to circulate, creating convection currents that move tectonic plates, leading to the spreading of the seafloor and movement of continents.
How Does Seafloor Spreading Effect Continental Drift?

Plate tectonics is the theory that Earth's lithosphere is divided into large plates that move and interact with each other, resulting in geological phenomena like seafloor spreading.
What kind of activity causes seafloor spreading?
Seafloor spreading is caused by the movement of tectonic plates away from each other at mid-ocean ridges. As the plates separate, magma rises to the surface, solidifies, and creates new oceanic crust. This process is part of the theory of plate tectonics.
What role did seafloor spreading play in arranging the continents as they are today?
Seafloor spreading is the process by which new oceanic crust is created through volcanic activity at mid-ocean ridges. As this new crust forms, it pushes the existing crust apart, which in turn causes the continents to move. This movement of the tectonic plates, driven by seafloor spreading, plays a significant role in shaping the arrangement of continents as they are today through the theory of plate tectonics.

Which process causes the earth's crust to be continuously formes by volcanic activity?
Seafloor spreading
What causes volcanoes to form at spreading boundaries?
Please make the question clearer. There are converging and diverging boundaries but not spreading boundaries. Plates move but don't spread. Please make the question clearer

What is the primary force that cause the seafloor to spread and continental to drift?
The primary force that causes the seafloor to spread and continents to drift is plate tectonics. This process is driven by the movement of molten rock in the Earth's mantle, which generates forces that push apart tectonic plates, leading to seafloor spreading and continental drift.
Is the following sentence true or false when solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
True. When solid mantle rock rises during seafloor spreading, the decrease in pressure causes decompression melting, resulting in the production of magma. This magma can then rise to the surface and form new oceanic crust.
