Answer:
Discovering that the physical fit of continents is one piece of evidence.
The lava cools so quickly in the cold water that it is called "pillow lava.” The evidence collected by advanced technology indicated that Earth's crust was moving.
Earthquakes and volcanic activity are also evidence.
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other

Answer:
natural period = 22.341 × 10³ s
not expecting development of tides
Explanation:
given data
average depth = 19.9 meters
length = 156 km = 156000 m
to find out
the natural period of oscillation of Long Island Sound
solution
we know that natural period formula that is
natural period = 
................1
here l is length and h is average depth
put here value in equation 1
natural period =
natural period = 
natural period = 22.341 × 10³ s
here i think of very long dam expected length 30 to 50 km be built from coasts straight out to sea or ocean without enclosing
tidal phase difference are introduce across the dam
that leads to significant water level differential in shallow coastal sea
but here not expecting development of tides
