Answer 1

Answer:

a)

Core is the densest part of the Earth. It is divided into the inner and the outer core. The core of the Earth has a diameter of approximately 7000km. It is made up of Nickel (Ni) and iron (Fe) and thus it is also known as NI

b)

Tectonic activity is responsible for some of Earth's most dramatic geologic events: earthquakes, volcanoes, orogeny (mountain-building), and deep ocean trenches can all be formed by tectonic activity in the lithosphere.
