What type of earthquake wave can travel through both liquids and solids?
a.
p waves
b.
s waves
c.
focus waves
d.
surface waves

select the best answer from the choices provided

a

d

a.P waves

Explanation:

P waves are the waves produced by Earthquakes that can travel through liquid and solid matter, this is because of their characteristics, and they are often the ones that are more detected in the seismographs because of that ability to travel across liquids and solids, the P waves are the responsibles for the back and forth movement of the surface of the earth when earthquakes happen.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
