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.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

the answer you are looking for is d. there are no holes for blood to enter or leave the system. your welcome
