GEOLOGY

Detailed explanation-1: -A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them.

Detailed explanation-2: -Geologists study the earth, its subsurface and all the processes acting on the earth.

Detailed explanation-3: -Geologists are scientists who study a planet’s solid features, like soil, rocks, and minerals.

Detailed explanation-4: -Geologists record the seismic waves and study how they travel through Earth. Different types of seismic waves behave differently. The speed of the waves and the paths they take reveal the structure of the planet. Using data from seismic waves geologists have learned that Earth’s interior is made up of layers.
