which layers of the earth have scientists been able to explore
because they haven't quite gotten that far in technology to create a machine to go to the flaming hot center of the earth
Scientists have been able to determine the composition of earth's layers using various ways. In most cases, samples have been taken and studied so as to determine the layers of the earth.
Only the crust. The temperature and pressure increases as you go further down into the earth.
making inferences based on data from seismic waves.
Severals methods are all combined to give the scientist info on the layers of the Earth. For example they study the influence of the earth on orbits of the moon and other planets (mass distribution of the earth, mass density). They study the way seismic waves go through the earth which gives knowledge of layers. They use wave to sound. They examine sample of earth.
True, scientists have not been able to eliminate the threat of future pandemics.
making inferences based on data from seismic waves.
Scientists can study natural environmental elements (such as trees, layers of silt and clay at the bottom of bodies of water, etc.) in order to glean data about climates dating back to thousands or even millions of years before.
Since glass was invented, the scientists were able to create the microscope. If this was never invented, the scientists would never have been able to discover cells.

they just do it cause they are scientists
The crust. We have not been able to access the other layers.
