What is the trigger for a turbidity current

What can cause a turbidity current to occur?

Turbidity currents are caused by earthquakes and collapsing slopes. Once the current is set, the turbidity water can rush downward and alter the seafloor’s physical structure.

What is an example of a passive margin?

Well-known passive margins are the conjugate margins of Greenland, India and Australia.

What is the difference between an active and a passive continental margin?

An activate continental margin can be found at the continent’s leading edge, where it is crashing into the oceanic plate. The remaining coastlines have passive continental margins.

What are the two types of continental margins?

There are two types of continental borders: passive and active. The lithospheric plate boundaries are often associated with active margins. These margins are often referred to as transform or convergent margins. They can also be places of high tectonic activity such as earthquakes and volcanoes.

When two plates slide past each other what is it called?

A transform plate boundary is when two plates slide horizontally past each other. The San Andreas Fault is a well-known transform plate border, and is responsible for many California earthquakes. Multiple types of plate boundaries can be found around a single tectonic plate.

What will happen if two plates move towards each other?

When two plates move towards one another, they converge or merge. A convergent boundary is the collision of two plates moving towards one another. Large, destructive earthquakes can result from the collision. The result of two continental plates colliding is large-sized folded mountains.

What do two stuck tectonic plates need in order to break loose from each other?

What do two tectonic plates that are stuck together need to be free? They require energy to separate from one another.

What happens when you slide the two crackers against each other?

Transform Boundaries – Place the crackers side-by-side and slide one forward (away) and one backwards (towards you). Plates can often catch on each other when they slide between one another. An earthquake occurs when they are freed. San Francisco lies on a transform fault.

What plate boundary happens when two plates slowly crash into each other?

Plates that collide or crunch together are known as “Convergent Boundaries”. The plates only move by a few centimeters each year. This means that collisions last many millions of years. The images below show how an oceanic plate collided with a continental one.
