Geology and Earth's Features

The video introduces the history of Earth, focusing on key vocabulary such as equator, geologist, and geology. It explains the role of geologists in studying rocks and Earth's formation. The Earth's formation, movement, and surface features, including oceans and continents, are discussed. Key geological factors like heat, pressure, and time are highlighted, with examples like the Grand Canyon illustrating Earth's history.
