What is it called when the earth's plates spread apart?
When Earth's plates spread apart, it is known as seafloor spreading. This process occurs at mid-ocean ridges where new crust is formed as magma rises up from the mantle and solidifies. As the plates move apart, they create new oceanic crust.
What happens when 2 tectonic plates spread apart?
When two tectonic plates spread apart, it creates a divergent boundary where new crust is formed as magma rises and solidifies between the plates. This process leads to seafloor spreading and the formation of features like mid-ocean ridges.
Which theory of plate movement involves magma rising all the away from the lowrer mantle to spread apart plates?
The theory of plate movement that involves magma rising all the way from the lower mantle to spread apart plates is known as seafloor spreading. This process occurs at mid-ocean ridges where new oceanic crust is formed as magma ascends and solidifies, pushing the plates apart.
What process causes earths plates to move?
The movement of Earth's tectonic plates is caused by the motion of convection currents in the mantle. These currents are driven by the heat generated from the decay of radioactive isotopes and by the heat leftover from the formation of the Earth. As the mantle material moves, it drags the overlying tectonic plates along with it, causing them to spread apart, collide, or slide past each other.
What are three things that can happen as plates spread apart?
Mid-ocean ridges can form as new crust is created at divergent plate boundaries. Earthquakes can occur as the plates pull away from each other. New ocean basins can develop as the plates move apart.
Do Earths Tetonic plates move apart?
Yes they do.
What do you get when the plates spread apart?
When the plates move apart they will more than likley create a large creak, Depending on how far they move apart. It would be a small creek.
What earth plates spread apart slowly?
Divergent boundaries such as the Mid-Atlantic Ridge and East Pacific Rise are examples of earth plates spreading apart slowly. This process results in the continuous formation of new oceanic crust as magma rises to the surface and solidifies.
What is it called when the earth's plates spread apart?
When Earth's plates spread apart, it is known as seafloor spreading. This process occurs at mid-ocean ridges where new crust is formed as magma rises up from the mantle and solidifies. As the plates move apart, they create new oceanic crust.
What is the name of the boundary were to plates of the earths crust move apart?
Constructive because new land is 'constructed'
What is is a spreading boundary?
a spreading boundary is when 2 plates spread apart from each other.
What happens when 2 tectonic plates spread apart?
When two tectonic plates spread apart, it creates a divergent boundary where new crust is formed as magma rises and solidifies between the plates. This process leads to seafloor spreading and the formation of features like mid-ocean ridges.
Do transform plates move together or apart?
Transform plates move sideways past each other in opposite directions along a fault line. They are neither moving together nor apart, but rather horizontally in opposite directions.
What are volcanoes and what causes them?
a volcano is a rupture or opening in the earths crust. caused by convergent (coming together) or divergent (moving apart) plates
Why does the ocean floor spread apart at the ridge?
Because as tectonic plates move away from each other, the ocean floor spreads apart and fills the gap.
Which theory of plate movement involves magma rising all the away from the lowrer mantle to spread apart plates?
The theory of plate movement that involves magma rising all the way from the lower mantle to spread apart plates is known as seafloor spreading. This process occurs at mid-ocean ridges where new oceanic crust is formed as magma ascends and solidifies, pushing the plates apart.
Which theory of plate movement involves magma rising all the way from the lower mantle to spread the plates apart?
The theory of plate movement that involves magma rising from the lower mantle to spread the plates apart is known as seafloor spreading. This process occurs at mid-ocean ridges where new oceanic crust is formed as magma wells up and solidifies, pushing the plates apart in opposite directions.
