What is cause and what is effect - landslide - volcanic eruption - crustal plate movement - tsunami - mountain building process - earthquake?

Answer 1

Landslides are caused by water making the ground on a hill loose and wet, allowing it to slide down the hill and crush everything in its path. Volcanoes erupt when magma from deep underground pushes its way up towards the surface, which explodes through the vent(s) releasing toxic gases, ash, and lava, which can burn and bury everything in the vicinity. Crustal plate movement is when tectonic plates in the lithosphere move around. It doesn't do that much damage. Tsunamis are formed when 2 oceanic plates collide, forcing a giant wave to occur that can stretch for miles, destroying everything in its path except for taller and sturdier buildings. Mountains are formed when 2 tectonic plates converge at their boundaries and push against each other, thus forcing one of them to rise upward. This causes the crust to rise, which will grow very high to form mountains. Natural earthquakes occur mainly along faults, large cracks in the crust. They form at the focus deep underground which produces several seismic waves which are picked up by seismographs. Directly above the focus is the epicenter, which is on the surface directly above the focus. The seismic waves are the shaking that is felt during an earthquake, and they can do different amounts of damage depending on the magnitude of the quake(s). Man-made earthquakes are not destructive unless caused by explosives. Otherwise, they are just caused by lots of people in an area clapping or stomping or yelling, etc. and are not destructive in any way.
