What do transform fault occur?
Transform faults occur when two tectonic plates slide past each other horizontally. These faults are found in mid-ocean ridges where plates are moving apart. The movement along transform faults can result in earthquakes.
What happens at a trench?
At a trench, tectonic plates are actively moving apart, leading to the creation of new crust. This process, known as seafloor spreading, can also involve the subduction of one tectonic plate beneath another. Trenches are typically sites where deep oceanic trenches are formed and earthquakes and volcanic activity can occur.
What does it mean if a plate boundary is divergent?
When two tectonic plates are diverging, that means that they are coming apart. Depending whether or not they are oceanic plates or continental plates, the outcome will be different. If two oceanic plates diverge, a rift valley will occur in the ocean; if the same is with continental plates an rift vally will occur on the continent.
A mid-ocean ridge forms along what plates?
A mid-ocean ridge forms along divergent plate boundaries, where tectonic plates are moving apart. These boundaries occur where magma rises to the surface, creating new oceanic crust and extending the ocean floor.
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.
Do Ocean Trenches Occur where plates are moving apart or where They are moving apart?
Ocean trenches occur where plates are moving towards each other and one plate is being pushed beneath the other in a process called subduction. Trenches are formed at convergent plate boundaries where oceanic crust is being forced downward into the mantle.
At what boundary does sea-floor spreading occur?
Consider. In sea-floor spreading, the plates are spreading apart; in other words diverging. So sea-floor spreading occurs at a divergent boundary,
What happens when two continental plates?
If the plates are moving together from opposite directions, the colliding edges will uplift into mountain ranges. If the plates are moving apart, a rift valley will form. If the plates are moving together at oblique angles, a fault zone will occur.
What directions do plates move in relation to trenches?
Trenches occur in subduction zones, so one plate (usually oceanic because it is more dense) is subducted beneath the other plate, so the plates are moving towards each other
Why does an ocean trench occur?
oceanic trenches occur where tectonic plates collide and one is pushed underneath the other.
What type of volcanic eruptions occur most often when plates are moving apart?
Most common would be a fissure eruption of basaltic magma.

What conditions are needed for an earthquake to occur?
because of moving plates
Why does floor spreading occur?
Because of plate tectonics. Because it's 2 plates underwater that are moving apart. Magma rise up to where the 2 plates are separating to fill in the gap. Seafloor spreading occurs underwater.
Cite evidences to show that earthquakes occur at the boundaries between plates?
example of these is the plates are moving in different ways and when it move the earthquake will occur
