What is it called when the earth's crust splits apart?
When the earth's crust splits apart, it is called a rift. This process occurs when tectonic plates move away from each other, creating a gap in the crust. Overtime, this rift can lead to the formation of new ocean basins or rift valleys.
What pushes the tectonic plates apart?
The process that pushes tectonic plates apart is called seafloor spreading. Magma rises from the mantle through divergent boundaries, creating new oceanic crust. As the new crust forms, it pushes the existing plates away from each other, causing them to move.
The stress force that pulls on the crust where two plates are moving apart is called .?
tension
What is the process by which lithospheric plates move apart creating spaces that are filled with hot magma is called?
The process by which lithospheric plates move apart, creating spaces that are filled with hot magma, is called seafloor spreading. This occurs at mid-ocean ridges where new oceanic crust is formed as magma rises from the mantle and solidifies at the surface.
What is it called when two ocean plates move apart and new crust is formed?
Seafloor spreading
What happens when the plates move apart towards and slide past?
When tectonic plates move apart, it creates a divergent boundary. As the plates separate, magma from beneath the Earth's surface can rise up, creating new crust. This process can lead to the formation of volcanic activity and mid-ocean ridges.
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.
Do trenches occur where plates are moving apart?
Trenches form where plates are moving towards each other in a convergent plate boundary, not where they are moving apart. At divergent boundaries, such as mid-ocean ridges, plates are moving apart, creating new crust.
Which layer are the plates in?
the plates are apart of the crust,the upper layer of the earth
How are new sections of the Earth's crust formed?
New sections of the Earth's crust are formed through a process called seafloor spreading. This occurs at mid-ocean ridges where tectonic plates move apart, allowing magma to rise up and solidify, creating new crust.
How does the process of seafloor spreading occur with two tectonic plates moving away from each other?
Seafloor spreading happens when two tectonic plates move apart. Magma rises up from the mantle through the gap, creating new oceanic crust. As the plates continue to move apart, the new crust pushes the older crust away, causing the seafloor to spread.
What is the force that stretches or pull apart the crust called?
When there is a divergent boundary, regardless if the plates are ocean-ocean or continental-continental, tensional stress pulls on the crust. Rocks have weaker tensional strength than compressive strength, so they are easier to pull apart.
