According to plate tectonics, the plates are in constant motion with an average rate of ________ per year.
According to plate tectonics, the plates are in constant motion with an average rate of ________ per year.
The correct option is B 2.5 cm
The movement of the plates generates three
kinds of tectonic boundaries. First one
is convergent, where plates move into one another. The second one is,
divergent, where plates move apart. And the third one is transformed, where
plates move sideways in relation to each other. They move at a rate of three to
five centimetres per year. The rate of spreading along the mid-Atlantic Ridge
is about 2.5 centimetres per year on average. It is 25 km in a million years.
So, the above information shows that
according to plate tectonics, the plates are in constant motion with an average
rate of 2.5 cm per year. Thus correct option is B. Other options are not
suitable.
