What plate boundary happens when two plates slowly crash into each other?
Convergent boundaries — where crust is destroyed as one plate dives under another.
What happens when two tectonic plates slide past each other?
When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
What happens when 2 plates catch?
At convergent boundaries, where plates push together, crust is either folded or destroyed. When two plates with continental crust collide, they will crumple and fold the rock between them. A plate with older, denser oceanic crust will sink beneath another plate. The crust melts in the asthenosphere and is destroyed.
What does a conservative plate boundary cause?
A conservative plate boundary, sometimes called a transform plate margin, occurs where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement. The shockwaves created produce an earthquake .
What are the 4 types of plate boundary?
Tectonic Plates and Plate Boundaries
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
What is it called when two plates move apart?
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other.
When two of Earth’s plates pull apart it is called?
Divergent or constructive plate boundaries. The plates diverge and this causes the construction of new rock. It happens when two tectonic plates pull apart and rock from the mantle rises up through the opening to form new surface rock when it cools.
What are the 4 plate boundary types?
Plate Boundaries: Convergent, Divergent, Transform.
Why are there no volcanoes at a conservative plate boundary?
At a conservative plate margin , the plates move past each other or are side by side moving at different speeds. As the plates move, friction occurs and plates become stuck. Pressure builds up because the plates are still trying to move. There are no volcanoes at a conservative plate margin.
What landforms are created at conservative plate boundaries?
A large scale landform found along a conservative plate boundary is a fault line. One of the most active fault lines in the world is the San Andreas fault line in California, USA.
What landforms are caused by plate tectonics?
Landforms Caused by Plate Tectonics
- Fold Mountains. The compressional forces stemming from a convergent plate boundary, where two plates collide with one another, can create fold mountains.
- Ocean Trenches.
- Island Arcs.
- Ocean Ridges.
