Two key pieces of evidence that led to the discovery of how an ice age can happen are the study of ice cores, which provide a record of past climate conditions, and the identification of Milankovitch cycles, which are variations in Earth's orbit and axial tilt that can influence climate over long periods of time. These pieces of evidence helped scientists better understand the mechanisms that can trigger ice ages.
Pieces of evidence for sea floor spreading include the presence of mid-ocean ridges where new crust is formed, symmetric magnetic striping on either side of mid-ocean ridges, age dating of oceanic crust that shows it gets older as it moves away from ridges, and the discovery of pillow basalts and other volcanic rocks on the ocean floor.
the age of the rocks in the sea floor is all the same
To summarize, there are three types of geological evidence of the age of the earth. These are:Gradual processes of rock formationThe fossil recordRadioactive dating
Most people will tell you that Columbus' voyages proved it, but the truth is, we already had a pretty good idea the earth was round by 1492. Actually, Aristotle, an ancient Greek thinker, proved it using geometry by digging holes at different latitudes on the same day of the year and measuring shadows. Going into the Age of Discovery, the whole "flat earth" notion was more of a misconception than a belief.
The discovery of radioactivity in 1896 by Henri Becquerel led to the development of radiometric dating techniques, such as radiocarbon dating, which revolutionized the method of assigning an age to the earth by providing more precise and accurate estimates based on the decay of radioactive isotopes.

His actions led to the Age of Discovery, also called the Age of Exploration (Columbus, Magellan, La Salle, Ponce de León, etc.
The discovery that started the neolithic age was farming
Europe.
The Age of Discovery was fueled by written travel accounts and popular maps that were printed and sold widely.
The Age of Discovery began in the 15th century, around the late 1400s. This era marked a period of exploration and discovery by European powers, leading to significant voyages to various parts of the world.
The Renaissance and Reformation influenced the Age of Discovery by promoting intellectual curiosity, scientific inquiry, and religious reforms. The spirit of humanism from the Renaissance encouraged exploration and discovery, while the Reformation challenged established authority, leading to voyages of discovery funded by new nations seeking wealth and power. This convergence of cultural, religious, and technological changes fueled the Age of Discovery.
