The theory of plate tectonics
elastic rebound theory
The theory is known as quantum theory or quantum mechanics. According to this theory, particles such as electrons can only absorb or release energy in discrete amounts called quanta. This means that their energy levels are quantized rather than continuous, leading to the observation that energy absorption and release occur in discreet steps rather than smoothly.
The theory of continental drift.
Cohesion tension is the theory that explains how water is moved from roots to leaves.
the impact theory.
elastic rebound theory
Due to the disturbances in tectonic plates
elastic rebound theory
elastic rebound theory
the theory explains how Earth's plates form and move. it also explains how plates interact ,producing volcanoes,mountain range ,earthquakes,and featurs of the ocean floor
theory of plate tectonics
The theory of plate tectonics helps to explain how earthquakes and volcanic eruptions occur.
Plate tectonics explain earthquakes and volcanoes so does the theory of continental drift.
The Elastic-Rebound theory explains how earthquakes occur. Rocks on opposite sides of a fault are subjected to force, causing them to shift. They absorb strength which causes them to deform and exceed their internal strength. A sudden movement occurs along the fault and this causes the energy and rocks to go back to their pre-deformed state.
If by "why" you mean "what," a well tested framework that explains a wide range of observations in science is called a theory.
Romania hasn't a special theory on earthquakes.
it is a Theory! :)
