Do most earthquakes occur on fault lines?
Yes, most earthquakes occur on fault lines because these are locations where tectonic plates experience stress and movement, causing them to release energy in the form of an earthquake. Fault lines are areas where the Earth's crust is weak and more prone to seismic activity.
What is a sentence for strike-slip fault?
The San Andreas Fault in California is a famous example of a strike-slip fault, where the movement of the two adjacent blocks is horizontal and parallel to the fault line.
When rocks break they move along the surface called?
When rocks break, they move along the surface in a process known as faulting. This movement can occur due to tectonic forces, causing the rocks to break and move along fractures known as faults.
Does an earthquake always occur where there is a build up of friction along a fault?
Not necessarily. While earthquakes are often caused by the release of built-up friction along a fault line, they can also occur due to other factors such as volcanic activity or other types of tectonic plate movements that do not involve friction along a fault.
What is a tectonic fault?
A tectonic fault is a fracture in the Earth's crust where rocks on either side have moved relative to each other. This movement can occur horizontally (strike-slip fault), vertically (normal fault), or in a complex motion (thrust fault). Faults are a primary source of earthquakes.
