Used around the world, magnets are important tools with a variety of uses. Transportation is one important use for magnets, like
on the maglev train shown in the picture. Unlike most trains equipped with wheels and axles, these trains use magnetic fields to
transport people at speeds of up to 600 miles per hour! While standard trains rest on the tracks beneath them, maglev trains
Levitate, or hover, above rails, without touching them. Based on properties of magnets, which best explains how a maglev train is
able to move so quickly while "floating above its tracks?
Magnets push air particles away, so magnets on the train and on the rails
push air against each other.
Maglev trains have extremely powerful magnets, greatly decreasing the
force of gravity and allowing them to float
The magnetic poles on both the bottom of the train and the top of the rails
are similar, so they repel one another
D)
Magnets at both ends of the track have opposite poles of magnets
attached to the front and back ends of the train.

the concept of nucleosome occupancy, which reflects the fraction of cells from the population in which a given region of dna is occupied by a histone octamer

answer: i cant find your answer. do u have another way i can answer it for you : )

explanation:

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.
