True or false:

oceanic crust is most like granite in composition overall.

pressure and temperature increase as you move deeper below earth’s surface.

to learn about earth’s interior, geologists study how seismic waves move through earth.

the core is earth’s outer skin of solid rock.

The answers would be:

False

True

True

False

If you'd like to know more about this, read on:

The oceanic crust is formed from the volcanic vents that erupt under water. The rocks that are formed from these eruptions are mafic, because they are compose magnesium and iron. Examples of mafic rocks are basalt and gabbro.

The Earth is made up of several layers. The deeper you go, the more heat and pressure. It gets really hot at the core because of different factors. One of them is the outer core and the inner core. The outer core flows around the solid core, which creates friction, thus creates heat. The outer core is also responsible for the electromagnetic property of the Earth.

Because seismic waves behave differently when they encounter different materials, geologists are able to use this to determine the different states of the layers beneath the Earth's surface. It helps them to determine whether the layer is molten, semi-molten or even solid.

The core is not the Earth's outer skin. The layer described is actually the CRUST. The core is the deepest layer of the Earth. It is solid and mostly made up of iron. The crust on the other hand is the outermost layer, and it is the layer that we live on.  

i think the answer is 95 hope this
