Mountain form is created when the
earth’s crust urges the tectonic plates to plunge against each other convergent
boundary which forces the land to grow upwards into a mountainous form.

A tsunami is a series of ocean waves generated by sudden displacements in the sea floor, landslides, or volcanic activity. In the deep ocean, the tsunami wave may only be a few inches high. The tsunami wave may come gently ashore or may increase in height to become a fast moving wall of turbulent water several meters high.

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little.

Earthquakes are formed through the shifting of tectonic plates, beneath the earth’s surface.
The level of movement can determine the severity and magnitude of the natural hazard, which can result in damage both socially,
environmentally and economically.

Earthquakes are caused by friction between two tectonic plates that either converge, diverge, transform which cause the earth’s crust to move. The centre of an earthquake is called an epicentre. The magnitude of an earthquake is measured by an amplitude.

Many mountains were formed as a result of Earth's tectonic plates smashing together.

Tsunamis, earthquakes, volcanoes and mountains are caused by the movement of tectonic plate, which makes up the Earth’s crust. When the plates move and push towards each other, they converge along the tectonic plate boundary and form an upwards crack (the convergent boundary); this forms mountains and volcanoes. When the plates scrape past each other, they cause earthquakes, which subsequently cause tsunamis. The epicentre of earthquakes happen where the tectonic plate boundaries are; and the amount of movement of the tectonic plates and the friction between them determines the magnitude of the earthquake, measured on the Richter scale. Earthquakes can then result in tsunamis. They are the rippling of water, and can be caused if the epicentre is in the ocean, or if the aftershock is strong enough.

When two tectonic plates
overlap underwater, it causes large, rushing waves. It is similar to
an earthquake, but underwater. Before a tsunami occurs, the water in the ocean
rushes backwards and returns as powerful, crashing waves. The waves
then move away from the source of the earthquake, and onto the land. The magnitude
of the tsunami is measured on a Richter scale, which is on a scale of 1 to 10,
10 being the worst.

Earthquakes are caused by vibrations in the earths crust which are caused by the movement of tectonic plates. Earthquakes in Australia are caused by movements along the faults as result of compression in the earths crust. The size or magnitude of earthquakes is determined by measuring the amplitude of the seismic waves recorded on a seismograph and the distance of the seismograph from the earthquake. Earthquake magnitude was traditionally measured on the Richter scale. It is often now calculated from seismic moment, which is proportional to the fault area multiplied by the average displacement on the fault. The amplitude of the shaking caused by an earthquake depends on many factors, such as the magnitude, distance from the epicentre, depth of focus, topography, and the local ground conditions.

Earthquakes are caused by two tectonic plates crashing and rubbing together, causing the earth’s crust to shake because of friction. Earthquakes can have a varying magnitude, with the more severe earthquakes causing more damage. The epicentre is a point on the earth’s surface directly above the point where an earthquake originates.

Tsunamis are caused by sudden movement in the ocean due to earthquakes, landslides on the sea floor, large volcanic eruptions or meteorite impact on the sea floor. The magnitude of tsunamis are measured on a Richter scale.
