If you imagine the shadows a CD can cast you'll get the idea.
Aristotle believed that the Earth was spherical in shape because of the observed curvature of its shadow during a lunar eclipse, the way ships disappear over the horizon, and the circular shape of the Earth's shadow on the moon during a lunar eclipse.
In ancient times, many people believed that the Earth was flat. This belief persisted until the 6th century BC when Greek scholars, such as Pythagoras and later Aristotle, theorized that the Earth was a sphere based on observations of the stars and shadow patterns during lunar eclipses.
Because it is impossible to show both.
If Earth were flat, the distribution of thermal energy would likely differ due to the altered surface area and angle of incidence of solar radiation. The regions near the center of the flat Earth would receive more direct sunlight and experience higher temperatures, while the edges would receive less sunlight and be cooler. This could lead to more extreme temperature variations across the flat Earth compared to the current spherical Earth.
Historically, observations of lunar eclipses, the phenomenon of ships disappearing over the horizon, and the ability to see different constellations from different locations on Earth were used as evidence to demonstrate that the Earth is not flat but rather a sphere. These observations, along with mathematical calculations and later space exploration, have further confirmed the Earth's shape.
try to look and observe the lunar eclipse. it's when the earth's shadow covers the moon. when you see it, the shadow of the earth is curved
it seems flat however its at such a small angle that it shapes ito a sphere
circle,flat,round
If the Earth were flat, it would cast a straight and uniform shadow, similar to a rectangular shape, as it would obstruct the light from the Sun in a consistent manner. The size and orientation of the shadow would vary depending on the position of the Sun in the sky.
that the earth is round just like what Magellan said ... `The church says the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in a shadow than in the church"
All flat maps do, globes do not.
Polygons are flat shapes
The church says the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in a shadow than in the church.
Shapes have flat surfaces in plane geometry. They can also be described as two dimensional shapes.

A square shadow can be cast by any opaque object that has a flat surface with right angles, such as a square block, a rectangular prism positioned correctly, or a cube. Additionally, a circular object can create a square shadow if it is illuminated at a specific angle or if it is placed in front of a square frame that alters the shape of the light passing through it. However, the most straightforward sources for a square shadow are geometrically square objects.
