FIRST OFF ID0414442662 THAT WAS A DUMB ANSWER
Knowledge of the Earth's interior is based on the reactions of seismic waves from earthquakes to the density and state of materials that they encounter. Seismic waves travel at differing speeds through different materials (and also, at different speeds through material of different states, i.e., liquid or solid). Because we know the size of the Earth, by measuring how long it takes to pick up on seismic activity on opposite sides of the Earth, we can gauge about how much of the Earth is solid, liquid, made of a certain material, etc.
Some of it, also, is based on our current understanding of how the Earth formed - mainly, that as our planet formed and cooled, the heavier materials such as metal sunk to the center.
Rock that is torn off and expelled by volcanism is studied as another indicator of what lies below the surface. Another clue lies in meteorites that have landed on Earth known as Chondrites. These can indicate the material from which planets are formed. The How_do_scientists_know_about_the_Earth's_interiorof Earth's magnetic field and gravitational properties also indicate or strongly infer what lies deep in Earth's interior.
Knowledge of the shallower (but otherwise difficult to access) oceanic crust and mantle has been gained due to a process known as obduction where oceanic crust is forced over continental crust. These rocks are known as Ophiolites and give Geologists direct access to the rocks in question
why do you think scientists study earths interior?if you were a scientists ,will you undertake a study of the earths interior?
rocks and seismic waves
that the earth is going to end in 2 days
Based on the materials that make up each layer

bananas are eatin by the earths interior
rocks and seismic waves
the mantle
scientists use seismic waves to map earths interior by seismographs that measure the times at witch seismic waves arrive at different distances from an earth quake.

that the earth is going to end in 2 days
Because of the study of seismic waves from earthquakes
Scientists learn about the Earth's interior through the use of seismographs. Since seismic waves travel at various speeds when passing through different types of material, scientists will be able to formulate the conditions of the Earth's interior.
The earths interior is cold
Based on the materials that make up each layer
Scientists use seismic waves to study Earth's interior. Seismic waves travel through the Earth and can be detected far from their source.
