Early mapmakers thought continents might have moved based on their observation of
a. magnetism
b. rock and fossil evidence
c. matching coastlines
d. earthquakes and flood

C. matching coastlines

Explanation:

The theory of continental drift was originally proposed in 1912 by German meteorologist and geophysicist Alfred Wegener (1880-1930), who formulated it based, among other things, on how they seemed to fit the shapes of the continents on each side of the Atlantic Ocean, such as Africa and South America. This had previously been speculated by some mapmakers.

this is poiselle's equation from fluid mechanic in physics. mech eng

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
