once they had arrived home Adam had wondered what a tsunami was and how it occurred
hey dad what is a tusnami
well a tsunami also known as a seismic sea wave is actually a series of waves in a water body which can sometimes be cause by any of theses disasters such as earthquakes , landslides or even a submarine
what is the cause of this tsunami
in this case the cause of the tsunami was caused by an earth quake and most tsunamis are caused by earthquakes. earthquake occurs when a large area of the Earth's crust suddenly moves. When this happens underwater, big gaps may appear on the ocean floor which aren't visible to us until the waves appear . When water moves in to fill this gap, a tsunami is born.
where do tsunamis mostly occur
Tsunamis occur most often in the Pacific Ocean and Indonesian because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones. this is also around the ring of fire wear most earthquakes occur.
how does this affect our land
well this can affect our land very much depending on how big the tsunamis is in the earths systems we have 4 spheres , lithosphere, hydrosphere,atmosphere and biospheres but the tsunamis can mostly affect the hydrosphere and biosphere which is the sea and our land this can also effect us humans and anmals by loose of homes, deaths and food
so do plate tectonics cause this tsunami as well
yes indeed plate tectonics play a role in earthquakes being caused called a subduction zone . an area where an oceanic plate is being forced down into the mantle by plate tectonic forces causing a earthquake to occur with the tsunami . the friction between one plate to another can cause a huge wave
how do scientist know when a earthquake will happen .
well scientist use seismographs which is a instrument used to detect when a earthquake will occur sending off alarms to phones
