erosion
The sudden movement could result in an earthquake.
Those would be tectonic plates.
Erosion happens in the earths crust and it happens because of that layer is exposed to that weather
The earths crust is moved rather than pulled by things called convection currents. This is when heated rock from the earths core rises up and reaches the crust where it cools. It then sinks down again and carries on in a circle which moves the crust
you get hotter and hotter
Plate
it is the movement of the earths crust. it moves inwards towards other plates so the earths crust moves upwards therefore forming mountains, volcanoes etc
That's when we have a lunar eclipse.
In a subduction zone, an oceanic plate moves under another plate (whether continental or oceanic). Sometimes pressure builds up, and earthquakes occur.
A sudden movement of the Earth's crust is called an earthquake.
I found that folding happens
most times earthquakes occur
