Two things geologists study is the process that creates Earth's features and search for clues about Earth's history
They drill holes into the earth and collect rock samples.
Convection of liquid metals in the outer core creates the Earth's magnetic field.
geology was born 200 years ago. by this time, geologists only knew about the things on the surface or things about the surface. They also knew that the earth was a sphere and that there were 7 land masses, and that the land masses were surrounded by water.
Not just millions. Earth has sustained life for several billion years.

Geologists
Before Darwin proposed his Theory of Evolution, it was widely believed that the Earth was only 6,000 years old. Geologists noticed that the Earth changed gradually over time (tectonic plates shifting to create volcanoes, mountains, etc) in order for such changes to create the Earth known at that time, it would have to be building up such changes over millions of years, thus creating the idea of Earth's immense age which allowed for evolution to create the diverse species known today. This theory of gradualism (as it was called) was adapted into Darwin's theory to apply to the species and their gradual changes.
Geologists study the Earth's structure and composition, which includes the different layers of the Earth and the types of minerals and rocks present. They also study Earth's history, including the processes that have shaped the planet over millions of years.

People who study the Earth are often called geologists. Geologists study the Earth's processes, materials, and history to better understand its composition and structure.
Geologists have divided Earth's history into manageable units called eons, eras, periods, and epochs. These divisions help scientists study and understand the Earth's geological and biological history over millions of years.

Yes, Geologists use the relative dating metod on earth.
In the most recent episode of a single supercontinent, it was called Pangea, or Pangaea.
Oceanographers study the ocean. Geologists study the earth.
