Complete: According to the Theory of Tectonic plates, the Crust layer ______ broken (divided) into so many pieces. So, these pieces are the so-called the Tectonic Plates.

• is

• is not

The plates move using three types of movements: convergent, divergent and transform.

• True

• False

An example of convergent (moving together) movement is The Himalayas.

• True

• False

The divergent movement happens when...

• ...plates move apart.

• ...plates move towards each other.

• ...2 plates move sideways with respect to each other.
