FLAT EARTH Flashcards
(24 cards)
It is an old belief model that the earth is plane or discoidal in form.
FLAT EARTH MODEL
believed that the world is a disk in the ocean
Early Egyptian, Mesopotamian, and Homer (Greek philosopher)
thought that the earth is like a disc floating in water where an arched bowl separates the earth from the heavens.

History of the Spherical Earth Model
pythagoras
anaxagoras
aristotle
eratosthenes
s introduced the idea of the round model of the earth in the 6th century BC.
pythagoras
observed that during lunar eclipse, the earth’s circular shadow was reflected on the moon’s surface.
anaxagoras
listed several arguments for a spherical Earth:
* Earth was also spherical since the moon and the sun were both spherical
* The North Star is closer to the horizon for places nearer the equator
* When the ship sailed, the hull disappeared first, which implied that the surface of the earth was curved.
aristotle
arguments of aristotle
- earth is spherical since moon and sun is spherical
- The North Star is closer to the horizon for places nearer the equator
- When the ship sailed, the hull disappeared first, which implied that the surface of the earth was curved.
attempted to measure the
circumference of the earth.
eratosthenes
He determined the angle that the sun rays made with the vertical direction by measuring the shadow a vertical stick cast

Modern Evidence Supporting Spherical Earth Model
- spacecraft photos
- oblate spheroid earth
- lunar eclipse
- time zones
- riding a plane
- A nearly perfect sphere
oblate spheroid earth
Earth is slightly flattened at the poles and bulging a little at the equator
oblate spheroid earth
the shadow of the earth formed on the one side of the moon shows a dark circle.
LUNAR ECLIPSE
- The shape that casts in the moon at which direction is it pointed shows spherical shape.
lunar eclipse
The time difference in different places in the world is due to the presence of a time zone.
* It can only be explained if the world is round and continuously rotating on its axis.
time zones
Airplanes are capable of traveling in a straight line without falling off any edges even for a period of time and it can circle the earth without stopping
riding a plane
The curvature of Earth on the horizon is noticeable if you travel in
transatlantic flight
